The Big Science of STOCKPILE STEWARDSHIP

At the height of the Cold War, the US possessed more than 30 000 nuclear warheads and exploded, on average, about one of them per week at a desert complex known as the Nevada Test Site. In 1992, after the Cold War ended, President George H. W. Bush halted production of all nuclear weapons and signed an authorization bill containing the Hatfield-Exon-Mitchell Amendment, which instituted a nine-month moratorium on nuclear explosive tests. His successor, Bill Clinton, extended the moratorium, and the US hasn't exploded a nuclear weapon since.
