A huge opportunity to save the U.S. taxpayers money, generate up to $23 billion in revenue for the Treasury, and improve security is right under the government’s nose. The U.S. has nearly 400 metric tons (MT) of highly enriched uranium (HEU), a fissile material used in nuclear weapons, that is not necessary for U.S. defense needs and either has been or should be declared surplus and properly disposed of.
Although not necessary for defense purposes, this vast store of HEU could be used for nefarious purposes by terrorists. With just enough to fill a shoebox, terrorists could create what is known as an improvised nuclear device that has the potential for a blast on par with the weapon that devastated Hiroshima, Japan, in 1945. They could do this within minutes if they gained access to the material—a distinct possibility given the chronic and well-documented weaknesses in securing nuclear materials at numerous U.S. sites.
Despite this danger, one of the most practical ways of reducing the risk has fallen by the wayside. The pace of converting surplus, expensive-to-secure HEU into low enriched uranium (LEU), which is unusable in weapons, has slowed to a snail’s crawl.
Just years ago, this process—known as downblending—was occurring at a rate close to ten times that of the downblending rate planned for the next four decades. The reason for the slow-down is that the Department of Energy (DOE) has not made downblending a priority.
The U.S. government has the capacity to ramp up downblending of surplus HEU to previous levels, and even exceed them. Also, far more HEU can be declared surplus than has been. The results would be win-win: Jobs would be created during the economic downturn; billions in revenue could be generated for the U.S. Treasury while security costs could be radically reduced; and Americans would be less vulnerable to devastating terrorist attacks.
In an investigation into the government’s downblending efforts, POGO has found:
- As much as 300 MT of HEU is unnecessary for America’s defense needs and can be designated as surplus.
- Downblending more HEU into LEU would reduce a security risk, cut government spending, and raise up to $23 billion through sales of the LEU to nuclear power plants (minus the cost of downblending).
- The federal government has slowed efforts to downblend the HEU already declared surplus from a high of 20 MT downblended in fiscal year (FY) 2004 to 3 MT to be downblended in FY 2010.
- The government plans to downblend 90 MT of HEU from now until 2050, a rate of only 2-3 MT a year.
- The government has the capacity now to downblend at a much faster rate.
- A blueprint to “transform” the U.S. nuclear weapons complex does not include increasing the downblending rate.
- The DOE has slowed its rate of dismantling the backlog of retired nuclear weapons, creating a hurdle to increasing the downblending rate.
- The DOE’s lack of emphasis on downblending weakens efforts to encourage other nations, such as Russia, to reduce their stockpiles of weapons and fissile materials.
- Security of nuclear materials is still insufficient. For example, there are three varying security standards for the same kind of nuclear material, depending on which government agency is in charge. While security of the nuclear weapons complex has improved since 9/11, there have been some troubling steps backwards; the results of performance tests make it clear that security is uneven, posing significant risks.
When President Barack Obama took office, he acknowledged that securing nuclear materials is critical to global security. “We must ensure that terrorists never acquire a nuclear weapon. This is the most immediate and extreme threat to global security….Al Qaeda has said it seeks a bomb and that it would have no problem with using it. And we know that there is unsecured nuclear material across the globe. To protect our people, we must act with a sense of purpose without delay.”
The President did not overstate the threat. Fissile material—particularly highly enriched uranium (HEU)—is a prime target for rogue states and nuclear terrorists. With only approximately 110 pounds of HEU, enough to fit in a shoebox, it is possible to create within minutes an improvised nuclear device (IND) that has the potential for a blast on par with the weapon that devastated Hiroshima, Japan. As Nobel Prize-winning physicist Luis Alvarez explained:
With modern weapons-grade uranium…terrorists, if they had such material, would have a good chance of setting off a high-yield explosion simply by dropping one half of the material onto the other half. Most people seem unaware that if separated U-235 [highly enriched uranium] is at hand, it’s a trivial job to set off a nuclear explosion….Given a supply of U-235…even a high school kid could make a bomb in short order.
Yet, nations around the globe continue to keep stocks of HEU which pose unnecessary security risks, and the U.S. is no exception. The U.S. currently has an estimated HEU inventory of 500-600 metric tons (MT)—equivalent to 20,000-24,000 warheads.
To combat the risk posed by unsecured fissile material around the globe, in April 2010 President Obama called for and hosted a nuclear security summit in Washington, DC. The intent of the summit was to “prevent proliferation…by bringing together more than 40 nations…with the goal of securing the world’s vulnerable nuclear materials in four years.” While the President can be commended for his leadership on bringing this issue to the global stage, it is problematic that he has not taken meaningful action to reduce our own stock of HEU. If the U.S. wants other nations to secure their fissile materials and advance a world free of nuclear weapons, we have to lead by example and reduce our own HEU inventory.
Although the Obama Administration has stated that “modernizing our nuclear infrastructure” is a priority, its version of modernization is to invest in Cold War-weapons production policies rather than in genuine post-9/11 modernization efforts to secure HEU in the U.S. For instance, the Administration is increasing programs that extend the life of the warheads, known as Life Extension Programs (LEP), at the expense of programs that secure nuclear materials, such as dismantlement and downblending, a process that transforms surplus HEU into a safe form of uranium called low enriched uranium (LEU). LEU is not desired by terrorists, and is useable as fuel for nuclear power plants, yet the rate of downblending has slowed. The Administration is also pouring at least $3.5 billion into the construction of a “modern” Uranium Processing Facility (UPF) that does little to accelerate the downblending rate and could actually expand U.S. capability to produce new HEU components of nuclear weapons. Furthermore, despite Obama’s global leadership on nuclear materials, and unlike the last two administrations, the Obama Administration has not yet declared any HEU surplus to national security needs so that it can be downblended. This Cold-War style of “modernization” is being driven mostly by DOE’s and the privately run weapons labs’ campaign to create doubt in the reliability of our nuclear arsenal, even in the face of scientific research indicating otherwise.
This report is an attempt to recapture the term “modernization” and use it to describe how the U.S. can invest in programs that respond to the modern threat of nuclear terrorism. A modern complex only requires the amount of HEU necessary to ensure the reliability of the arsenal, and permanently removes surplus HEU so that it is not itself a security threat and a burden requiring costly systems to store and protect it. True modernization would accelerate the current glacial pace of downblending, declare more HEU surplus to national security needs, and decrease the backlog of warheads sitting in storage awaiting dismantlement. This approach to modernization makes the U.S. more secure, advances our global nuclear security agenda, and generates revenue for the U.S. Treasury from the sale of Cold War-era HEU that has been transformed to LEU for use in nuclear power reactors.
Between 1945 and 1992, the U.S. produced 1,045 MT of HEU for nuclear weapons secondaries (which are added to single-stage nuclear weapons to create a thermonuclear explosion); naval propulsion reactors; and research reactors. Although the U.S. stopped producing HEU in 1992, we still have the world’s next-to-largest stock, second only to Russia.
The exact amount of U.S.-owned HEU is classified. That classification designation is challenged by arms-control advocates. POGO also argues that the unnecessary secrecy is counter to national security as it undermines international nonproliferation efforts by inhibiting a public accounting of downblending efforts. Former Director General of the International Atomic Energy Agency and the winner of the 2005 Nobel Peace Prize Mohamed ElBaradei and the Norwegian Minister of Foreign Affairs Jonas Gahr Støre recognized this point in 2006, saying that “to build trust, countries with civilian and military HEU stockpiles should be encouraged to release clear inventories of those stockpiles, and to publish a schedule under which the remaining HEU will be verifiably downblended.”
According to the last inventory made public, the U.S. possessed 740 MT of HEU in 1996. Since then, approximately 127 MT have been truly secured through downblending, several dozen metric tons have presumably been consumed by the Navy to power its nuclear fleet, and a modest amount has been consumed by research reactors. That leaves approximately 500-600 MT of HEU that is being kept on hand in nuclear warheads, additional secondaries, and in various forms being stored at Y-12 National Security Complex in Oak Ridge, Tennessee.
Accelerate the Downblending Rate
The most important step to modernize the nuclear weapons complex is to accelerate the downblending rate of surplus HEU. Downblending involves diluting HEU with depleted, natural, or low enriched uranium (LEU) to produce a substantially larger quantity of LEU and render the HEU unusable in weapons. NNSA contracts with facilities to do the downblending: the Nuclear Operations Group of Babcock & Wilcox in Lynchburg, Virginia (B&W-Lynchburg); Nuclear Fuel Services in Erwin, Tennessee (NFS), which was recently bought by B&W; and to a lesser extent, the Savannah River Site near Aiken, South Carolina (SRS) and Y-12. Although it is NNSA that tasks these facilities with downblending activities, it is the NRC—with its significantly weaker security standards—that is responsible for overseeing safety and security at NFS and B&W-Lynchburg.
There are pragmatic reasons to downblend our surplus HEU. One reason is that doing so will make the U.S. more secure from terrorist attacks. Unlike HEU, LEU is not weapons-usable and therefore does not pose serious security risks or require expensive security systems to guard it. Terrorists have no interest in LEU because reactor-grade LEU contains less than 20 percent U-235, making it virtually impossible to sustain an explosive nuclear chain reaction.
Another reason is that downblending our surplus HEU would advance the U.S. goal for world leaders “to secure all vulnerable nuclear material around the world within four years.” For this goal to be realized, the U.S. must practice what it preaches. As Harvard University’s Matthew Bunn notes, “Convincing foreign countries to reduce and consolidate nuclear stockpiles, to put stringent nuclear security measures in place, or to convert their research reactors from HEU to LEU fuel will be far more difficult if the United States is not doing the same at home.”
A third reason to downblend our surplus HEU is that it would generate revenue for the U.S. Treasury. A lot of it. In fact, the U.S. is sitting on a veritable gold mine, one that could be worth billions of dollars. Russia, for instance, has been downblending 30 MT a year and shipping it to the U.S. since 1995, and projects to earn as much as $12 billion from having partnered with the U.S. on the “Megatons to Megawatts” program to downblend its surplus military HEU. And LEU is in demand as fuel for nuclear power reactors, both in the U.S. (nuclear power provides 19 percent of U.S. electricity) and around the world. In fact, demands for LEU are likely to increase from anywhere between 38 and 80 percent by 2030 as nuclear power technology improves. The amount of HEU that the U.S. could declare surplus and downblend could be worth as much as $23 billion, minus the cost of downblending.
Despite the benefits of downblending, U.S. policy-makers have placed little priority on accelerating the rate of transforming the HEU that has already been declared surplus. Congress has instead focused on multi-billion dollar facilities for the disposition of U.S. plutonium, such as the troubled Mixed Oxide Fuel Fabrication Facility, and on the disposition of HEU and plutonium abroad. And the Administration’s FY 2011 budget will actually slow the downblending process: the budget shrank from $39.2 million in 2009 to $34.7 million in 2010, and shrank again in the FY 2011 request to $26 million.
The DOE has also made it clear that downblending is not a priority. NNSA boasted in 2009 that “374 metric tons (MT), or roughly 15,000 nuclear weapons-worth, of highly enriched uranium (HEU) was removed from U.S. stocks”: 174 MT had been declared surplus in 1994, and 200 MT was declared surplus in 2005. But NNSA’s statements are misleading. First, the term “removed” refers to how much HEU has been declared surplus, and while it has technically been removed from the military stockpile, it appears that only 127 MT has actually been removed by downblending it into LEU. (Appendix A) Second, of the 200 MT declared surplus in 2005, 160 MT were reserved for naval fuel; only 40 MT is to be downblended. NNSA’s schedule for transforming the approximately 90 MT of remaining surplus HEU, most of which was declared surplus in 1994, has slowed to an almost glacial pace: downblending the 90 MT isn’t scheduled to be completed until 2050, averaging out to only 2 MT per year. (Appendix A) This rate is unnecessarily slow—NNSA downblended 20 MT in 2004 (Appendix B), 14 MT in FY 2008, and 10 MT in FY 2009 (Appendix A), clearly indicating that a rate far higher than 2 MT per year is possible.
In fact, NNSA has the capacity to downblend significantly more than even the 20 MT per year. One of the privately owned facilities NNSA contracts with for downblending, B&W-Lynchburg, performed almost no downblending in 2009. POGO sources say the facility is considering closing its downblending operation because it is not profitable, a move that would even further impede U.S. downblending goals. In addition, POGO has learned from sources that NFS, too, has a large unmet capacity for downblending, with a number of downblending lines sitting idle. Y-12 also has a downblending capacity, although it’s unclear how much of one. Y-12 could be given more capacity by utilizing mobile downblending units, which could cut down on transportation risks and costs, as the units could be located next to the Highly Enriched Uranium Manufacturing Facility (HEUMF).
In addition, more downblending prep work could be conducted at Building 9212, the facility at Y-12 where HEU is converted into the form that can be shipped for downblending. In a meeting with POGO, NNSA officials said a key reason the downblending rate has slowed so much is that Building 9212 is not a modern facility. As a result, the rate at which HEU is converted into the form necessary for downblending must be reduced so as not to “wear out” the building, NNSA told POGO at a meeting. But on closer examination, NNSA’s explanation doesn’t hold up.
As of 2004, $400 million had been invested in Building 9212 as part of a series of expensive upgrades to ensure 9212 is safe and operational until UPF is operational. POGO was unable to discover how much DOE spent between 2004 and the present on upgrading 9212, but Building 9212 performed the functions to support a downblending rate of 14 MT as recently as 2008. In addition, at least 50 percent of the processing time at Building 9212 is spent on extracting HEU from scrap material containing less than 1 percent HEU. This scrap should instead be declared waste and sent to the Waste Isolation Pilot Plant (WIPP), which would allow 9212 to focus on converting HEU into the form that can be downblended.
Given the excess capacity at B&W-Lynchburg, NFS, and possibly Y-12, as well as the capacity 9212 has for increased prep work, NNSA should be able to significantly increase its downblending rate to at least 20 MT per year.
The U.S. stock of HEU is being stored across the country with varying degrees of security. While security of the nuclear weapons complex has improved since 9/11, there have been some troubling steps backwards; the results of performance tests make it clear that security is uneven, posing significant risks.  There are several reasons for this uneven security: complex-wide, there are differing federal agency interpretations of the threat to nuclear materials; three different security criteria for the same material; different armament and equipment to secure the material; dissimilar training standards for security forces; significantly different approaches to force-on-force security testing, with results that cannot be compared; and significant conflicts of interest in the use of the same contractors for protection and testing.
Three agencies—the Department of Energy (DOE), Department of Defense (DoD), and Nuclear Regulatory Commission (NRC)—are responsible for setting security standards for the HEU under their protection, and all three agencies have different security requirements for the same material. The majority of the nation’s HEU is stored at facilities managed by DOE’s National Nuclear Security Administration (NNSA), with most of that at the Y-12. DOE has, over the years, had numerous security standards based on estimates of potential adversaries’ capabilities called Design Basis Threats (DBT), some of which were rigorous—but the agency has recently weakened its security by adopting the malleable standard of the Graded Security Protection (GSP) plan. The GSP is classified, but sources tell POGO that it varies the security requirements from site to site. Furthermore, the GSP requires sites to be able to defend against fewer attackers than was required in the DBT, and has downgraded the capabilities of those attackers that the site must be prepared to defend against. Whereas the DBT provided a consistent bar to measure security, the GSP is more of a floating bar, able to be increased or lowered based on the alleged weaknesses and strengths of a particular site. According to sources, the GSP emerged after it was clear that several DOE sites could not meet the DBT and did not want to spend the funds to meet it. Another weakness of DOE’s security apparatus is that it employs members of its own protective force, who are not specifically trained as adversary forces, to test the security performance of its sites. The second largest stock of HEU in the U.S. is deployed and stored at DoD facilities in existing warheads and some in naval reactors. DoD’s protection strategy is strong in several ways, such as how sites are tested. Its Defense Threat Reduction Agency oversees testing of the security of nuclear materials, and the testing itself is conducted by Mighty Guardian, a unit of the Special Operations Command designed to mirror as closely as possible the size, armament, and tactical operations expected to be used by terrorist organizations. Mighty Guardian uses rigorous performance testing at the sites, often with a trained mock terrorist force called the Grizzly Hitch.
Smaller amounts of HEU are found at private facilities for processing and at universities with research reactors, whose safety and security is overseen by NRC. The NRC has by far the weakest security standards of all, and the Commissioners have rejected their staff’s recommendations to bolster the NRC’s DBT. Security of NRC’s licensed nuclear power reactors and nuclear facilities in the U.S. is provided by a hodge-podge of security contractors. The government testing of security at these various sites is done by Wackenhut, under contract with the nuclear trade association Nuclear Energy Institute (NEI). The adversary force used by NEI and Wackenhut to conduct force-on-force tests is a composite of guards from other sites. At a number of sites, the security contractor is Wackenhut. It doesn’t take a nuclear scientist to see this system is riddled with conflicts of interest.
Any New or Modernized Uranium Facility Should Advance Downblending
DOE’s lack of attention to downblending is also evident in its long-term plan to “modernize” the nuclear weapons complex, called Complex Transformation. The plan calls for consolidating most of the HEU and the activities involving HEU into one location, at Y-12, yet fails to set any downblending goals. When POGO asked why downblending wasn’t included, a high-level NNSA source told us that downblending had nothing to do with Complex Transformation, demonstrating NNSA’s failure to recognize just how much its inventory of HEU costs the complex, both in dollars and security risk.
NNSA’s vision for Y-12 is that it become the “Center of Excellence for Uranium and Canned Subassemblies.” The agency has already built the HEUMF, which is designed to be a more secure HEU storage facility, and is planning to build the $3.5 billion UPF as a replacement for production facilities and to house other missions at Y-12. Yet, it does not appear that this new modern facility will modernize NNSA’s approach to downblending.
NNSA does not plan to increase the HEU downblending rate from 2 to 3 MT per year when UPF is scheduled to be brought online in 2022. This, despite the fact that one of NNSA’s reasons for the 2-3 MT per year rate was to avoid overtaxing Building 9212. In other words, NNSA does not plan to utilize the new expanded capacity of UPF to bring downblending back up to the previous rates of 10-20 MT per year, much less ramp up the rate to more than 20 MT per year. NNSA does, however, project very high targets of production of 80-200 secondaries per year at UPF. This high level of secondary production means the U.S. could manufacture secondaries to replenish the entire arsenal in as little as eight years; this seems excessive given that sources tell POGO there are already thousands of secondaries in storage, and given that a recent study for NNSA by the highly respected JASON group found that the life of the nation’s nuclear warheads, including the HEU secondaries, can be extended safely and certifiably for decades.
As a result, POGO is not convinced that UPF is necessary as it is currently planned. As the ground has not yet been broken on the project, nor a contractor selected, it is not too late to cancel or refocus the project. Y-12 already has the capacity to ensure the reliability of the stockpile as well as to manufacture new secondaries in case unforeseen problems arise with secondaries in deployed warheads. Y-12 itself admits that without UPF, it can support a “baseline throughput of approximately 125 secondaries and cases per year.” According to POGO sources, during the B61 (aircraft-launched warhead) Life Extension Program, Y-12’s Building 9212 was able to successfully remanufacture the HEU component of the secondary. This follows a pattern of successfully ccomplishing its mission: Y-1’s Building 9212 also had themanufacturing capacity to handle the LEP of the W87 (Minuteman III) and the current LEP of the W76 (submarine-launched warhead). Therefore, renovating Building 9212 may be a better alternative for modernizing the complex than waiting for UPF to be completed. NNSA has already invested at least $400 million in renovating Building 9212; and even though other “major investments” would be necessary “for continued operations in the existing facilities,” those investments are unlikely to even begin to approach the cost of building a new facility.
Additionally, history has shown that we can count on DOE’s estimates for the cost and timeline of constructing UPF to be wildly optimistic. For example, when DOE built the HEUMF, costs ballooned from $97 million to $549 million—a 465 percent increase. In another example, the National Ignition Facility (NIF) was sold to Congress in the early 1990s with a reported cost estimate of $1 billion and an original completion date of 2002. The most recent cost estimate to build and equip the NIF is $3.5 billion with a completion date after 2012—250 percent over budget and at least 10 years behind schedule. Current estimates for the UPF put the cost of construction at around $3.5 billion, plus the facility’s lifetime operations and security costs, and the completion timeline at ten to twelve years. If history holds true, and there is no reason to believe it won’t, both the cost and construction timeline of the UPF will increase dramatically.
If Congress decides that the UPF is necessary, it should be concerned that the facility appears to do little to address the several hundred metric tons of HEU that could be designated surplus (which we will discuss in a later section of this report). Without a strategy for using UPF to accelerate the downblending rate, Y-12 will fall far short of being a “Center of Excellence for Uranium and Canned Subassemblies.”
Market Impact of Increased Downblending is Overstated
One possible reason for the lack of priority on downblending may be the concern that the U.S. could negatively affect the international market price for LEU by flooding the market. This is a reasonable concern, but one that has clear solutions. Worldwide, there are 435 active commercial nuclear reactors. In 2006, about 60 percent of their fuel, or 66,500 MT of uranium, came from mining production. Even though enrichment of the natural form of uranium into usable LEU involves a “lengthy, complex and expensive process,” there are some interests which may not want to see more LEU come from downblended HEU. For example, the World Nuclear Association, which represents the “people and organisations of the global nuclear profession,” including uranium mining, conversion, and enrichment companies, states that “Highly-enriched uranium from weapons stockpiles is displacing some 10,600 tonnes of U3O8 [natural uranium] production from mines each year, and meets about 13% of world reactor requirements.”
One option to alleviate fears of flooding the market is to store LEU at a very low cost—much lower than the cost of storing HEU—until market conditions change. Some in the nuclear industry even recognize this store of LEU as “a friend” as it enables “us to skate over supply disruptions with no one running out of fuel.” The government could also reduce market anxiety by publishing a plan for when LEU would be released, in what form, and in what quantity, as suppliers say the market can adjust if it can see the LEU coming. In an effort to address such concerns, Congress has already directed the Secretary of Commerce to review projected demand for LEU and set import limitations on uranium so as not to cause a disruptive effect on the market. And in yet another step to avoid negatively affecting the market, the Government Accountability Office (GAO), in a March 2008 report about depleted uranium supplies in the U.S., recommended that DOE complete as soon as possible a comprehensive uranium management assessment so that DOE can “quickly react to rapidly changing market conditions to achieve the greatest possible value from its uranium inventories.”
DOE Has No Financial Incentive to Speed Up Downblending
Another possible reason for DOE’s low priority on downblending is that there is no mechanism for any of the revenue generated by the sale of LEU from downblended U.S. HEU to return to DOE. Instead, the revenue is returned to the Treasury. Currently, downblending has to compete for funding with a number of other projects at DOE, and has thus fallen to the bottom of the list of funding priorities. Without an incentive to downblend, NNSA will continue to store HEU and will continue to move at a snail’s pace toward downblending. Congress could fund downblending, and offset those funds with revenue generated by DOE’s sale of LEU from downblended U.S. HEU.
Declare More U.S. HEU Surplus to National Defense Needs
Another step the U.S. could take to genuinely modernize our nuclear weapons complex is to declare as surplus the HEU that is no longer needed for defense needs and to downblend it. This is an area where the President must take the lead: only the President has the authority to designate an amount of HEU surplus to defense needs, thus making it available for downblending.
As with downblending, however, there has not been enough progress—or even interest—in declaring additional HEU surplus. This lack of priority is evident in the language of the Administration’s FY 2011 budget request: “The funding profile for the U.S. Uranium Disposition program is declining in the future because the large quantities of surplus HEU have already been disposed of or are in the pipeline.” This statement suggests that the Administration doesn’t believe there is additional HEU that can be declared surplus. This belief is false, as there are hundreds of metric tons of HEU that could be declared surplus.
Misconceptions Surround Naval Reactor HEU Requirements
A reason decision-makers may think there isn’t HEU that could be declared surplus is that there is a common misconception that HEU not otherwise needed for the U.S. nuclear arsenal is all needed for naval reactor fuel to power submarines and aircraft carriers. The Navy currently has reserved 100-160 MT of HEU—as the Navy uses an average of 2-3.5 MT of weapons-grade HEU annually, this is enough fuel supply for the next 28-80 years.
That said, the Navy will one day probably require more fuel. Yet, reliance on HEU is not in line with the U.S. goal to secure loose fissile material around the globe. The International Panel of Fissile Materials (IPFM) warns that “it will be difficult to assure that some HEU withdrawn from safeguards for use in naval fuel has not been diverted to weapons.” There also exists proliferation risks associated with the continued reliance on HEU as naval fuel, as asserted in the 2008 IPFM Report:
The use of HEU fuel by naval nuclear propulsion programs may make future nuclear disarmament agreements more difficult. As reductions in the nuclear-weapon arsenals proceed, the relative size of naval stockpiles of HEU could increase, and concerns could develop about their potential conversion to nuclear weapons.
This concern would be exacerbated if the Navy goes forward with plans to use HEU-powered reactors to propel surface ships.
One possible solution would be to design new naval propulsion systems to run on LEU fuel. Although popular wisdom contends that HEU reactors are more efficient than LEU because of the longer periods between refueling, these efficiency claims are challenged by the fact that HEU refueling is an expensive and elaborate multi-year process. In both U.S. and Russian submarines, refueling “involves cutting through the submarine hull and removing the core,” which can take years. For example, it took more than two years to refuel the USS Alaska. As a result, other nations have switched to an LEU reactor, which reduces the refueling time to mere months. The time between LEU refueling is estimated to be 7.5-14 years. Both France and China use LEU, enriched at less than 10 percent, to fuel their submarines, and both India and Brazil are currently designing LEU-run naval propulsion reactors. It is also possible that naval nuclear ships can be powered with Thorium.
Either option will require an independent scientific analysis. (The Navy conducted a study in 1995 at the request of Congress and recommended against the use of LEU because it would be “uneconomic and impractical.” But there have been substantial technological advances on LEU reactors since 1995, as well as increased security concerns about HEU.) The study could be conducted by the GAO, which could also seek input from the National Academy of Sciences or JASON.
Hundreds of Metric Tons of HEU Being Stored at Y-12
The first place to look for HEU that can be declared surplus to U.S. security needs is Y-12. According to multiple sources, there is approximately 200-300 MT of HEU stored at Y-12 in various forms, including canned subassemblies and secondaries; POGO believes most of this could be declared surplus. An independent study by the GAO should be conducted to determine how much HEU Y-12 actually needs to keep on hand.
New Arms Control Agreements Provide Opportunity to Secure HEU
The U.S. currently has HEU in inventory set aside for military needs, but that amount has not yet been right-sized to fit the decreased arsenal. Although not yet ratified by the U.S. Senate, the new arms control deal with Russia (the New START Treaty) reduced the number of deployed operational warheads to 1,550 for each side. The U.S. could designate as surplus the HEU contained in its non-deployed warheads (also referred to as hedge or war reserve warheads), the HEU contained in retired warheads awaiting dismantlement, and most of the HEU being stored at Y-12. By POGO’s estimates, these amounts of HEU add up to more than 320 MT of U.S. HEU that can be declared surplus to military needs.
U.S. HEU Stockpile
Accelerate the Dismantlement Rate
A third step the U.S. could take toward genuine modernization of our nuclear weapons complex is to accelerate the dismantlement rate of retired nuclear weapons. Yet, this is another area where the U.S.’s stated goals and its actions aren’t in accordance. In recent years, there has been a dramatic drop in the number of warheads the U.S. has dismantled, thus slowing the amount of HEU becoming available for downblending. While the recent rates of dismantlement are classified, expert observers have estimated the average rate of warhead dismantlement dropped from 1,300 per year from 1990 to 1998, to the current rate of 350 weapons per year, which would not dismantle the backlog of 4,500 retired warheads until 2022.
Until the retired weapons are dismantled, they can still be used by the U.S. (or, theoretically, terrorists and rogue states), sending a mixed message to the nations of the world. Furthermore, the growing backlog of thousands of nuclear warheads in the dismantlement queue raises concerns about security because a number of the more secure military storage bunkers are filling fast. For example, the Air Force’s most secure facility, Kirtland Underground Munitions Storage Complex (KUMSC), is virtually filled, according to POGO sources. And now there may be thousands of additional nuclear warheads traveling down the pipeline as a result of the New START Treaty, and it is not clear that there are adequate secure facilities to store these additional surplus warheads.
NNSA defends its current sluggish dismantlement rate, claiming that the rate is hard to compare from year to year because of the complexities of different warheads. While this complexity may have something to do with the slow rate, it’s not the whole story. For instance, President Obama’s FY 2011 budget request for nuclear weapons-related investments increased by 14 percent and the request for dismantling retired weapons decreased by 39 percent.
If the President is serious about his stated goal to “ensure that terrorists never acquire a nuclear weapon” and to do so by acting “with a sense of purpose without delay,” he should increase the budget request for dismantlement. Even if he doesn’t, however, Congress now has a budget request and it could act quickly to remove the backlog in the dismantlement process by increasing the funds appropriated specifically for that purpose. NNSA would then be able to employ a second shift at the Pantex Plant in Texas. POGO believes this second shift would create the capacity to increase the dismantlement rate to 800-1,000 weapons per year, and if that capacity were put to use, the backlog of 4,500 warheads could be dismantled by 2015. That would make 112.5 MT of HEU available for downblending. The DOE could also assign dismantlement activities to the Device Assembly Facility at the Nevada National Security Site (formerly known as the Nevada Test Site), which has the same bays, cells, and gravel gerties that Pantex uses to dismantle weapons, according to POGO sources.
The U.S. has a fairly large footprint of HEU that is not needed for military purposes: more than 320 MT is contained in war reserve warheads, in retired warheads awaiting dismantlement, and being stored at Y-12.
Shrinking this footprint is a win-win situation. As stated in Securing the Bomb 2010, “incidents around the world make clear that urgent action is needed to improve security for nuclear stockpiles around the world and to keep nuclear weapons and the materials needed to make them out of terrorist hands.” Not only would shrinking our HEU footprint accomplish this by removing a prime terrorist target from our stocks, but it would also reduce security costs and generate significant revenue from the sale of LEU without in any way impeding our ability to maintain our nuclear deterrent. An additional benefit to declaring more HEU surplus, accelerating dismantlement, and accelerating downblending is that they provide a key diplomatic tool for advancing the U.S.’s global non-proliferation and nuclear security interests. For example, the U.S. has had a major effort underway for years to help Russia return HEU from the former Soviet states so that it could be downblended into LEU in Russia. As outlined under the HEU Purchase Agreement, Russia is well on its way to downblending 500 MT of HEU and has sold most of the resultant LEU to the U.S. The Purchase Agreement is coming to a close in 2013, and because Russia will still have hundreds of metric tons of HEU, many experts have pushed for a new agreement. However, without a commitment from the U.S. to reduce its inventory of HEU, the sentiment in Russia will persist that “Russia is one-sidedly reducing its nuclear weapons capability.” To facilitate a new agreement, the U.S. may need to commit to additional downblending in order to encourage Russia to do the same.
Yet, the U.S. has not made any substantial moves to shrink its dangerous and valuable stock of HEU. At best, this is due to a lack of focused leadership and prioritization of the issue. At worst, NNSA has hoarded its stock of HEU in a deliberate attempt to justify bloated budgets and to perpetuate its Cold-War paradigm. Whatever its cause, the slow pace of downblending HEU in the U.S. poses a security risk to the population, deprives taxpayers of a much-needed source of revenue, and sends the wrong message to the global community about the U.S. commitment to combating nuclear terrorism. It is particularly troubling that, as the U.S. has focused more attention on securing fissile materials globally, it has decreased its own rate of downblending and dismantlement. Developing and implementing a new downblending strategy should be an immediate priority. There are several hundred metric tons of U.S. HEU that can be better secured by being put on the path towards its safe and secure conversion to LEU.
A successful strategy will require stringent oversight of weapons dismantlement, analysis of how to maximize existing resources within the nuclear weapons complex to facilitate the downblending process, rethinking naval HEU needs, and transparency of the HEU and LEU stocks in order to prevent negatively impacting the uranium market. POGO has developed a number of recommendations to help accomplish this.
- The President should designate an additional amount of HEU, as much as 300 MT, surplus to defense needs and schedule that HEU for dismantling and downblending.
- The President should direct the DOE to accelerate the downblending rate of the approximately 90 MT of HEU that has already been designated surplus and scheduled for downblending so that the process is completed by 2015 rather than 2050. To accomplish this, the NNSA should increase the dismantlement rate at the Pantex Plant in Texas—up to 800-1,000 weapons per year—and open up the Device Assembly Facility at the Nevada National Security Site (formerly known as the Nevada Test Site) for additional dismantlement activities to allow the backlog of 4,500 warheads to be dismantled by 2015.
- Congress should appropriate additional funds to DOE for downblending and dismantlement.
- If Congress decides that the new Uranium Processing Facility is necessary, it should fence the appropriation for UPF to ensure that downblending, as well as activities to support downblending, is a core mission of the facility.
- NNSA should transfer the scrap material containing less than 1 percent HEU from Y-12’s Building 9212 to the Waste Isolation Pilot Plant (WIPP) in New Mexico to free up space for preparing HEU for downblending.
- Congress should task the GAO with conducting a study on the Navy’s HEU needs, the use of LEU fuel for any new naval submarines and nuclear surface ships, and on whether existing HEU reactor ships could be retrofitted with LEU reactors during the scheduled refueling process.
- Congress should task the GAO with studying the DoD’s, DOE’s, and NRC’s different standards for securing HEU in order to determine whether one or more standards is necessary, and what the security standard(s) should be.
- The DOE should make public an inventory of its HEU stocks.

Defense Threat Reduction Agency - The mission of the Department of Defense’s Defense Threat Reduction Agency is to safeguard America and its allies from weapons of mass destruction by reducing the present threat and preparing for the future threat.
Design Basis Threat - The Design Basis Threat describes the level of threats a protective force is required to defend against: the number of outside attackers and inside conspirators, as well as the kinds of weapons and size of truck bombs that would be available to terrorists. It is based on the Postulated Threat, which is the intelligence community’s best estimate of the threat faced by nuclear facilities.
Dismantlement - The National Nuclear Security Administration’s four-step nuclear warhead dismantlement process: retirement, return and storage, disassembly, and disposition.
Downblending - Downblending is the reduction of uranium enrichment levels from 80-90 percent to less than 20 percent, a low enriched uranium, which is of no interest to terrorists and is suitable for use as fuel in nuclear power plants and naval nuclear reactors.
Force-on-Force - Performance tests of the protective guard force that utilize mock terrorists to identify weaknesses in security of a site.
Graded Security Protection - The Department of Energy has replaced its Design Basis Threat Policy with the Graded Security Protection Policy, which is classified but is used as a standard by which the nuclear weapons facilities are to base their security requirements and by which DOE is to measure the effectiveness of the facilities’ security.
Highly Enriched Uranium - Highly enriched uranium is predominantly uranium-235 that has been enriched to a level of 80-90 percent, so that it is composed of atoms that can release enormous amounts of energy from a self-sustaining chain-reaction when split by neutrons.

 POGO raised awareness about the possibility that the U.S. nuclear weapons complex could be vulnerable to terrorists who are able to detonate an improvised nuclear device (IND) with the publication of its investigative report, U.S. Nuclear Weapons Complex: Security At Risk, October 1, 2001.

 Due to the sensitivity of information about INDs, POGO’s discussion of the issue is limited to public sources and is described in general terms. An IND explosion produces the same physical effects, catastrophic loss of life, and infrastructure destruction as a nuclear weapon explosion. It is qualitatively different from a “dirty bomb.” POGO used the conversion that 1 kilogram equals roughly 2.2 pounds. Matthew Bunn and John P. Holdren, “A Tutorial on Nuclear Weapons and Nuclear-Explosive Materials: Nuclear Weapons Design and Materials,” Securing the Bomb 2006, President and Fellows of Harvard College, September 6, 2006.

 The explosion from the nuclear bomb dropped on Hiroshima was created using the “gun type” method. The blast from the Hiroshima bomb was 13 kilotons; over 200,000 people died either in the blast or as a result in the five years following it.

 POGO arrived at this estimate, an admittedly wide range, based on the limited information that is publicly available about the U.S. HEU inventory: the U.S. had 740 MT in stock in 1996; 127 MT has since been downblended; and an additional, but much smaller amount has been used by research reactors. Department of Energy, Highly Enriched Uranium: Striking A Balance, January 2001, p. 2.

(Downloaded September 1, 2010) (hereinafter (DOE/CF-0047)) Also, since 1996, the Navy has consumed approximately 49 MT of HEU through its annual use 2 to 3.5 MT of weapons-grade HEU to power its nuclear fleet (14 years * 3.5 = 49 MT). The 3.5 MT per year figure comes from POGO inside sources. The 2 MT per year figure comes from Steven Aftergood and Frank N. von Hippel, “Report: The U.S. Highly Enriched Uranium Declaration: Transparency Deferred but not Denied,” NonProliferation Review, Vol. 14, No. 1, March 2007, p. 156. (Downloaded September 1, 2010) (hereinafter Report: The U.S. Highly Enriched Uranium Declaration: Transparency Deferred but not Denied) and Highly Enriched Uranium: Striking A Balance, p. 2.
 POGO arrived at this figure using the conversion that 1000 kg of HEU = 1 MT of HEU, and that an average modern nuclear warhead contains 25 kg of HEU in the secondary (600 MT x 1000 kg / 25 kg = 24,000 warheads).

 Through downblending HEU, “the weapon capability of HEU can be eliminated in a manner that is reversible only through isotope enrichment, and therefore, highly resistant to proliferation.” J. David Snider, “Candidate Processes for Diluting the 235U Isotope in Weapons-Capable Highly Enriched Uranium,” Prepared for Presentation at the American Institute of Chemical Engineers 1996 Spring National Meeting, February 1996, p. 2. (Downloaded September 1, 2010) Both enriching and downblending uranium involves altering the concentration of U-235, the type of uranium that fissions (the nucleus splits, releasing energy) easily. Natural uranium is just .711 percent U-235, the LEU that is employed as fuel usually falls between 3 and 5 percent, and the HEU used in nuclear weapons may surpass a 90 percent concentration. For every metric ton of HEU downblended, between 11 and 19 MT of LEU is produced. Nuclear Energy Institute, “How it Works: Nuclear Power Plant Fuel,” (Downloaded September 1, 2010); Sizes, “Separative Work Unit,” (Downloaded September 1, 2010) The ratio of LEU fuel produced from HEU is based on the enrichment level of HEU. POGO determined this range from a sampling of U.S. downblending milestones: the U.S. produced 250 MT of LEU from 20.8 MT of HEU; 220 MT of LEU from 12.1 MT of HEU; and 800 MT of LEU from 46.6 MT of HEU.

 In 2005, 160 MT had been set aside for naval reactors. Samuel Bodman, “Remarks by Energy Secretary Samuel Bodman to the Carnegie Endowment for International Peace,” Federal News Service, 2005, p. 6. (Downloaded September 1, 2010) (hereinafter “Remarks by Energy Secretary Samuel Bodman to the Carnegie Endowment for International Peace”) Some of that 160 MT has been used, and 31 MT was rejected by the Navy. This leaves somewhere between 100 and 160 MT on reserve for naval reactors. Presentation by Robert M. George at the International Nuclear Materials Management Annual Meeting, slide 3.
 POGO calculated this figure by subtracting the cumulative amount of surplus HEU NNSA has downblended to date (127 MT) from the cumulative amount it plans to have downblended by FY 2050 (217 MT): 217 MT – 127 MT = 90 MT. There is a discrepancy of 3 MT between what the NNSA says it wants to downblend by 2050 (217), and how much HEU has, according to public sources, been declared surplus and slated for downblending (174 MT in 1994 plus 40 MT in 2005 = 214). POGO cannot account for the discrepancy using the information that has been made public.
With its operations limited by a recent shutdown, NFS has long been under scrutiny for safety lapses, including some very dangerous incidents, and such issues have to be resolved before increasing its capacity.

 The $3.5 billion in costs were spent to design and construct the NIF facility and to install NIF’s 192 lasers and their associated components. However, to actually complete the goal of the project, NNSA created the National Ignition Campaign (NIC), the costs of which have also spiraled from $1.6 billion to over $2 billion. Furthermore, a recent GAO report found that “weak oversight by NNSA has allowed the lead NIC participant, Lawrence Livermore National Laboratory, to defer critical performance requirements, construction activities, and key equipment acquisitions needed for ignition experiments at NIF, which could delay ignition or other NIC goals beyond 2012.” Government Accountability Office, Actions Needed to Address Scientific and Technical Challenges and Management Weaknesses at the National Ignition Facility (GAO-10-488), April 2010, Executive Summary, pp. 1, 15.

 According to then-Energy Secretary Samuel Bodman, “160 metric tons, will be provided for use in propulsion systems for our nation’s nuclear Navy.” “Remarks by Energy Secretary Samuel Bodman to the Carnegie Endowment for International Peace,” p. 6. According to a POGO source, the Navy now has 100 MT of HEU reserved.
 The 3.5 MT per year figure comes from POGO inside sources. The 2 MT per year figure comes from Steven Aftergood and Frank N. von Hippel, Report: The U.S. Highly Enriched Uranium Declaration: Transparency Deferred but not Denied, p. 156.
 POGO determined this range by calculating that 100 MT / 3.5 MT per year = 28 years, and that 160 MT / 2 MT per year = 80 years.

 “The Budget requests $7.009 billion (B) for the [Nuclear] Weapons Activities of the NNSA. That is an increase of $624 million (M), or 9.8 percent, above the 2010 appropriation. The Budget requests an additional $273 M in the Nuclear Non-Proliferation (NNP) Account for programs that were funded within Weapons Activities in 2010. NNSA is requesting $80 M in construction funds and $113 M in operating expenses for a Pit Disassembly and Conversion Facility within NNP and another $80 M for preparation and transport of initial quantities of plutonium for disposition, including operation of the Advanced Recovery and Integrated Extraction System (ARIES) facility at Los Alamos. After correcting for those organizational shifts, the increase in weapons activities compared to comparable activities in 2010 is about $900 M or 14 percent.” Dr. Robert Civiak, “Enhancing Nuclear Weapons Research and Production to Support Disarmament?,” February 22, 2010.

 One of the recommendations in Expanded and Accelerated HEU Downblending: Designing Options to Serve the Interests of All Parties (p. 8) is, “The United States should be prepared to agree to expand and accelerate its own down-blending of excess HEU. The United States and Russia should agree to reduce their nuclear weapon stockpiles to low levels, and to reduce their HEU stockpiles to the minimum required to support those low levels of nuclear weapons plus a modest additional stock for naval fuel.”
