当前,世界主要产铀国家和地区有美国、加拿大、纳米比亚、南非、澳大利亚和尼日尔等。它们年产氧化铀约4万5千吨,而世界核电反应堆燃料年需铀量为4万吨,供求大致相当。但是,1979年美国三里岛核电站事故发生后,影响波及世界,好多新建电站推迟了投入运行的日期,从而造成世界范围铀供过于求。1980年年初起,铀价 At present, the world’s major uranium-producing countries and regions include the United States, Canada, Namibia, South Africa, Australia, and Niger. They produce about 45,000 tons of uranium oxide per year, while the world’s nuclear power reactor fuel uses 40,000 tons of uranium per year, and supply and demand are roughly the same. However, after the U.S. Sanli Island nuclear power plant accident in 1979, the impact of the U.S. nuclear power plant spilled over into the world, and many newly built power plants delayed the date of operation, resulting in an oversupply of uranium worldwide. From the beginning of 1980, uranium prices
