Unmaking the Bomb: A Fissile Material Approach to Nuclear Disarmament and Nonproliferation

“The development of nuclear power is fraught with infinitely greater dangers than were all the inventions of the past.” This warning was voiced to the US government by a group of Manhattan Project scientists led by James Franck in June 1945, one month before the first ever nuclear weapon was detonated at the Trinity test site in New Mexico’s Alamogordo desert. Two months later the world saw firsthand the unprecedented destruction that could be wrought by the military application of such weapons as two first generation nuclear devices were dropped on the Japanese cities of Hiroshima and Nagasaki. The key fissile materials, namely plutonium and highly enriched uranium (HEU), used in the assembly of these bombs are the same as those used in more modern designs of nuclear weapons today and are not necessary ingredients of fuel that is used to generate peaceful nuclear energy. This distinction between weapon-usable fissile materials that are the products of extensive enrichment or costly reprocessing of spent nuclear reactor fuel on the one hand and material that can be used as a fuel for the generation of peaceful nuclear energy without being immediately ready for incorporation into a nuclear weapon on the other, constitutes the foundational truth behind Unmaking the Bomb: A Fissile Material Approach to Nuclear Disarmament and Nonproliferation. The authors, all physicists, begin the book by providing a history of the discovery, application, and spread of fissile materials and the technology required for their production. They later go on to introduce a variety of ways in which the imbedded link between nuclear energy and nuclear weapons can be broken
