核能与核安全Nuclear energy and nuclear safety1、什么是核能核能是通过转化其质量从原子核释放的能量,是20世纪人类的一项伟大发现,并已取得了十分重要的成果。核能是人类最具希望的未来能源。人们开发核能的途径有两条:一是重元素的裂变,如铀的裂变;二是轻元素的聚变,如氘、氚、锂等。重元素的裂变技术,己得到实际性的应用;而轻元素聚变技术,也正在积极研制之中。可不论是铀,还是氘、氚,在海洋中都有相当巨大的储藏量。核反应可以通过各种各样粒子轰击来诱发。What is nuclear energy. Nuclear energy is released from the nucleus through the conversion of its quality, it is one of the greatest human discovered in 20th century, and has achieved important results. Nuclear energy is one of the most pro
