Cancel the plutonium fuel factory

July 19, 2016

Matthew Bunn and Gary Samore just published an op-ed arguing that the program to build a factory that converts excess plutonium from dismantled nuclear weapons into plutonium-uranium mixed oxide fuel for nuclear reactors has become too expensive. Although the two helped to launch the program in the mid-90s, they argue "It is time to stop throwing good money after bad and pursue cheaper alternatives that will serve our national security better" and "whatever we do with this plutonium in the long term, we should move to put it under international monitoring, and commit never again to use it in weapons..." You can read their complete argument here.

Fresh Thinking on Highly Enriched Uranium Research Reactor Conversions

| Feb. 03, 2016

Last week, a National Academies of Sciences, Engineering, and Medicine panel affirmed the goal of eliminating highly enriched uranium (HEU) from civilian use, while recommending step-wise conversion of high performance research reactors using weapon-grade uranium fuel and that the White House coordinate a 50-year national roadmap for neutron-based research. (Full disclosure:  I sat on that committee, and oversaw the NNSA reactor conversion program from 2006-9; this post, however, represents my views, not necessarily those of the committee or NNSA.)

All HEU Removed from Georgia, Again

| Jan. 12, 2016

In 1998, in Operation Auburn Endeavor, the U.S. government helped fly 4.3 kilograms of highly enriched uranium (HEU) and low-enriched uranium (LEU) from vulnerable facilities in war-torn Georgia to the Dounreay reprocessing plant in the United Kingdom. At the time, those in the U.S. government involved in the project, myself included, thought that was all the HEU there was in Georgia. So it was a surprise when the IAEA announced the removal of another 1.83 kilograms of HEU from Georgia – apparently now really the last of the HEU there.

Summary of Nonproliferation funding in Obama Administration’s fiscal year 2016 Budget Request

| Feb. 24, 2015

The Obama administration is proposing to boost Department of Energy nonproliferation funding to $1.94 billion—more than a $300 million increase from what Congress appropriated last year—in fiscal year 2016. But this is an increase over the very low fiscal year 2015 budget proposed by the administration and then further cut by Congress. Both Congress and the Russian government have cut back on further U.S.-funded nuclear security work in Russia, and the Obama administration has yet to develop major new initiatives that could absorb those resources.

Don't Let Nuclear-Security Cooperation with Russia Lapse

July 03, 2014

Republicans and Democrats alike have traditionally understood that investing in nuclear security is a small price to pay compared with the devastating economic, political and social costs of nuclear terrorism. That’s why U.S. cooperation with Russia and other countries to secure vulnerable nuclear material has enjoyed bipartisan support.

Tenth Anniversary of Global Threat Reduction Initiative

| May 29, 2014

September 11, 2001 convinced decision-makers in Washington that terrorists were capable of carrying out catastrophic attacks on the United States. The idea that an individual or group could make a bomb from nuclear or radiological material was no longer just an outlandish scenario, but a realistic threat that needed to be addressed. Ten years ago this week, the Bush administration responded to that threat by establishing the Global Threat Reduction Initiative (GTRI).

Conflicting Views on Nuclear Security in House Armed Services Committee

| May 21, 2014

Funding U.S. programs that enhance nuclear security has been a controversial issue this year in Congress. The House Armed Services Committee (HASC) recently released its version of the National Defense Authorization Act (NDAA) for Fiscal Year 2015. The results are a mixed bag on the nuclear security front. The committee proposes picking up some of the slack the Obama administration left for nonproliferation programs — increasing the administration’s request by $10 million overall — but it also slashed a key nuclear security effort and called for putting all nuclear security cooperation with Russia on hold.

Select Quotes on Nuclear Security Funding from Congressional Hearings

May 12, 2014

The Obama administration has proposed significant cuts to nuclear security programs.   The House Armed Services Committee bill would reduce the scale of the cuts for one nuclear security program (the Global Threat Reduction Initiative) while aggressively slashing another (International Material Protection and Cooperation); the debate over nuclear security spending will likely continue throughout the year. I’ve pulled some select quotes from Congressional hearings on nuclear security, which I plan to update as needed.

Eliminating Potential Bomb Material from Japan’s Fast Critical Assembly

| Mar. 24, 2014

Today, the United States and Japan announced that Japan would eliminate all the plutonium and highly-enriched uranium at its Fast Critical Assembly (FCA) at Tokai-mura.  This is a tremendous step forward for nuclear security; for terrorists, this would be some of the best material that exists in any non-nuclear-weapon state.  The material includes 331 kilograms of plutonium, most of it weapons-grade, and 214.5 kilograms of weapons-grade HEU.  (The FCA also includes over a ton of material just at the 20 percent U-235 mark that defines HEU.)   The weapons-grade HEU is enough for four simple terrorist “gun-type” bombs or a larger number of trickier-to-build implosion bombs.  The plutonium amounts to more than 40 bombs worth of material.
