俄罗斯研制成功一种既安全又环保的核废料掩埋新法。核废料是指使用过的核反应堆燃料,其主要成分是少量的放射性核物质和大量稳定而又安全的液体。过去,处理这些溶液的方法是首先将它们装在特殊的容器中(俄罗斯使用混凝土罐,美国则使用不锈钢箱),然后深深地掩埋到地下。但混凝土和不锈钢容器都不能很长时间保存这些危险的放射性废料,因为混凝土会被微生物“吃掉”,而不锈钢会受到腐蚀。至今,已经发生过掩埋掉的核废料出现泄漏的事故。
Russia successfully developed a new method of burying nuclear waste that is safe and environmentally friendly. Nuclear waste refers to used nuclear reactor fuel, the main component is a small amount of radioactive nuclear material and a large number of stable and safe liquid. In the past, these solutions were handled by first packing them in special containers (Russia uses concrete cans and in the United States stainless steel boxes) and then buried them underground. However, both concrete and stainless steel containers can not store these hazardous radioactive wastes for a long time because concrete is “eaten” by microorganisms while stainless steel is subject to corrosion. To date, there have been leaks of buried nuclear waste.
