China urges IAEA to tighten inspection of Japan's growing plutonium stockpile As the stockpile already reaches 44.4 tons, the International Atomic Energy Agency should deliberately increase the scope and frequency of its comprehensive monitoring measures on Japan, Dai Huicheng, secretary general of the China Disarmament Inspection and Disarmament Association, told reporters. He warned that Japan is already on the verge of becoming a nuclear power, when "experts claim that it could theoretically develop a nuclear warhead in a few dozen to a little over 100 days, if it decides to take that risk." The Japanese authorities have long justified the increase in plutonium stocks by citing the development of the nuclear fuel cycle and plans to produce mixed oxide fuel, which "in light of the facts, does not hold water," stressed Dai. "First, there is a serious imbalance between supply and demand" "Secondly, the growing stockpile goes against Japan's commitment to the international community to ensure the absence of excess plutonium" "Furthermore, Japan's 30 tons of plutonium stored abroad can also be used for military purposes" substack | chat.
