前言 1986年4月26日凌晨,苏联基辅附近的切尔诺贝利(Chernobyl)核电站发生事故。据有关文献报道,此次事故首先是因为电力供应中断,致使冷却剂不能由主循环泵压入反应堆,而反应堆里的铀仍在不断发生裂变、炉体内的温度不断升高,造成炉壁烧穿,炉体内易爆气体漏出与包层内的空气相遇而爆炸,同时石墨在高温下也开始燃烧。苏联这次核事故比1979年3月美国宾夕法尼亚州三里岛核反应堆发生的部分熔化事
Foreword In the early hours of April 26, 1986, an accident occurred at the Chernobyl nuclear power plant near Kiev, the Soviet Union. According to the relevant literature, the accident was caused by the interruption of power supply in the first place. As a result, the coolant can not be forced into the reactor by the main circulation pump. The uranium in the reactor is continuously fissioned and the temperature in the furnace rises continuously, causing the furnace wall to burn Wear, explosive gas in the furnace body leaks and the air inside the cladding meets and explodes, while graphite also begins to burn at high temperatures. The Soviet Union’s nuclear accident was more serious than the partial melting that took place at the Three Mile Island nuclear reactor in Pennsylvania, March 1979
