Assessing the PRISM reactor as a disposition option for the British plutonium stockpile

The U.K. has more than 100 tons of plutonium which is not needed anymore. It is the world’s largest civilian stockpile. One of the solutions pursued by the British Nuclear Decommissioning Authority (NDA) is the use of this plutonium as fuel in the fast-spectrum PRISM reactor. Hereby, the plutonium is to be rendered proliferation resistant.

Together with her colleagues Christopher Fichtlscherer (Universität Hamburg) and Moritz Kütt (IFSH) Friederike Frieß analyzed this option using computer simulations. The results have now been published under the title “Assessing the PRISM reactor as a disposition option for the British plutonium stockpile” in Science and Global Security  (https://doi.org/10.1080/08929882.2019.1681736).
