铀,为一种银白色金属,是重要的天然放射性元素。人们熟知它,是因为它成为了目前最重要的核燃料。而平时我们常说的天然铀,指的是天然存在于自然界中的铀。目前,全球核电站所使用的核燃料基本来源于对陆地上天然铀矿的开采。随着世界核电事业的蓬勃发展,全球每年所需的铀资源量也在不断增加。虽然根据数据显示,全球铀资源量超过了1500万吨,但是,陆地已知常规天然铀储量,即开采成本低于每公斤130美元(通 Uranium, a silvery white metal, is an important natural radioactive element. It is well-known because it is now the most important nuclear fuel. And usually we usually say natural uranium, refers to the natural existence of uranium in nature. At present, the nuclear fuel used by nuclear power plants in the world is basically derived from the exploitation of natural uranium deposits on land. With the vigorous development of nuclear power in the world, the amount of uranium resources required annually by the world is also on the rise. Although the world’s uranium resource exceeds 15 million tons according to the data, conventional natural uranium reserves are known on land, ie, the cost of mining is less than 130 U.S. dollars per kilo
