Response to a consultation on the management of the UK’s plutonium stocks

June, 2011

In the 1950s, following World War II, the United Kingdom and a handful of other nations developed a nuclear weapons arsenal. This required the production of plutonium metal (or highly enriched uranium) purpose-built facilities. ‘Civil’ plutonium was also produced, since the facilities for separation existed and it was thought that this fissile material would prove useful in further nuclear power development. Fifty years on, the question of what to do with the UK’s separated plutonium stocks is an important one.


Tom Blees, President, of The Science Council for Global Initiatives, explores answers to the question, ""Do you agree that it is not realistic for the Government to wait until fast breeder reactor technology is commercially available before taking a decision on how to manage plutonium stocks?" I strongly disagree, and I hope that you’ll take the time to read this and consider the fact that the fast reactor option is far more imminent than you might have heretofore believed. Not only that, but it is arguably the best option by far.

Current Fast Reactor Development

Worldwide there are well over 300 reactor-years of experience with fast reactors. Russia’s BN-600 fast reactor has been producing commercial electricity for over 30 years, and Russia is beginning to build BN-800 reactors both for their own use and for China. India’s first commercial-scale fast reactor is about to be finished within a year or two. South Korea has already built a sizeable pyroprocessing facility to convert their spent LWR fuel into metal fuel for fast reactors, and have only refrained from starting it up because of diplomatic agreements with the USA that are due to be renegotiated in the near future. China is building a copy of the Experimental Breeder Reactor II (EBR-II) that was the mainstay of the Integral Fast Reactor (IFR) development program at Argonne National Laboratory in the USA. Japan has reopened their Monju fast reactor to continue that research, though it should be noted that Toshiba and Hitachi contested the wisdom of that decision, favoring instead the metal-fueled fast reactor design as exemplified by the EBR-II.

The advantages of metal fuel in fast reactors is difficult to overstate. Rather than attempt to explicate the details here, I would refer the reader to the following URL: This is a chapter from a book that deals at length with the Integral Fast Reactor (IFR). The advantages of this system in safety, economics, fuel utilization, proliferation resistance and plutonium breeding or burning far outstrip any of the other options mentioned in the consultation document.
