20 0 3年 1月 7日 ,我国首座高温气冷核反应堆在北京并网发电成功。高温气冷核反应堆是一种先进型核反应堆 ,也是国际核能界公认的安全性最高的反应堆。它能在发生事故时自动关闭 ,并将剩余热量排除冷却 ,从而不会发生燃料元件烧毁的现象。高温气冷核反应堆采用氦气作为冷却剂 On January 7, 2003, China’s first high-temperature gas-cooled nuclear reactor was successfully grid-connected in Beijing. High-temperature gas-cooled nuclear reactor is an advanced type of nuclear reactors, but also recognized by the international nuclear community’s most secure reactor. It automatically shuts off in the event of an accident and removes the remaining heat to cool, so that no burning of the fuel element occurs. High-temperature gas-cooled nuclear reactors use helium as a coolant
