Nuclear Issues

Ukraine-based journalist Maxim Tucker has just published two articles to claim that pro-Russian rebels in Eastern Ukraine are plotting to manufacture a dirty bomb with the help of Russian scientists, using radioactive waste from a storage facility at the Donetsk Chemical Factory.

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.

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.

As the Crimea crisis continues, the Bulletin of the Atomic Scientists asked a number of experts about what an appropriate short-term U.S. response to the crisis would entail, as well as how the crisis will affect U.S. policy towards Russia. Belfer Center Director Graham Allison was among those that participated.
