Abstract:
The International Atomic Energy Agency (IAEA) was formed in 1957 to promote the peaceful use of nuclear energy and to inspect civilian nuclear materials and activities to deter military diversions. To decide the frequency of inspections and inspection criteria, the IAEA set its safeguard standards with the objective of assuring “timely detection of diversion of significant quantities of nuclear material from peaceful nuclear activities to the manufacture of nuclear weapons.” The two nuclear weapon designs developed and detonated during World War II were the “gun-type” and “implosion” designs. Because implosion device technology requires much less fissile material than guntype technology, the IAEA significant quantity6 (SQ) values were determined based on the fissile material requirements of nuclear implosion devices like the plutonium-based “Fat Man” detonated over Nagasaki in 1945. Utilizing implosion designs perfected in the late 1940s, however, the explosive yields achieved in 1945 can be produced with much less fissile material. Table 1 lists the fissile material requirements of contemporary nuclear weapon technology. “Low Technical Capability” in Table 1 refers to the Mark III implosion device set off at Nagasaki. “Medium Technical Capability” refers to implosion designs perfected in the late 1940s and “High Technical Capability” in Table 1 refers to the implosion technologies the United States perfected in the 1950s.

Abstract:
Although much has been said about the fusion of China’s civilian and military sectors, no detailed, unclassified analysis has been done of how Beijing’s “peaceful” nuclear efforts might be exploited to make more nuclear warheads. Even the U.S. Department of Energy’s own explanations of the export restrictions it imposed on “advanced” nuclear exports to China failed to discuss this. This volume is dedicated to clarifying just what the connection could be. Much of it focuses on China’s advanced fast breeder reactor program and its related plutonium recycling efforts. As explained in this volume’s first chapter, “How Many Nuclear Warheads China Might Acquire by 2030,” the least burdensome way for China to achieve nuclear weapons parity with the United States is simply to use the weaponsgrade plutonium that its planned “peaceful” fast breeder reactor and reprocessing programs will produce to make primaries for the two-stage thermonuclear weapons designs they already have perfected. By exploiting this weapons plutonium and the highly enriched uranium and tritium that China can easily access or make, Beijing by 2030 could conservatively assemble an arsenal of 1,270 warheads (nearly as many as the US currently has deployed on its intercontinental missiles).
