Canada supplied India with the CIRUS nuclear research reactor, based on Canada’s NRX reactor, in 1954. It produced the plutonium for India’s first nuclear test in 1974. Canada sold 250 kilograms of plutonium from the NRX nuclear reactor to the Americans to produce nuclear weapons from 1955 to 1976. By 1965, the U.S. and Britain had amassed some 20,000 nuclear bombs made principally with Canadian uranium.
