摘　　要：朝鲜宁边地区有1座正在运行的5 MWe石墨反应堆。如果发生核事故,我国可能因放射性环境释放影响不得不采取应急响应行动,因此需要作出适当的应急准备。基于有限信息,从国际应急计划区和距离、切尔诺贝利核事故跨国应急实践两方面分析了宁边5 MWe石墨堆核事故跨国紧急情况。分析结果表明:我国领土不太可能在宁边5 MWe石墨堆应急计划区和应急距离以内;我国对其核事故跨国紧急情况的应急准备重点是当地食品和贸易限制。There is a 5 MWe graphite reactor in operation in Yongbyon,North Korea.In case of a nuclear accident,China could have to take emergency response actions as a result of possible radioactive materials released into environment due to the accident,which requires China to make appropriate emergency preparedness.Transboundary emergency of the 5 MWe graphite reactor in Yongbyon is analyzed from two aspects based on limited information:international planning zone and distance,and transboundary emergency practices of Chernobyl nuclear accident.The analysis result shows that it is unlikely that China’s territory is within emergency planning zones and distances of the 5 MWe graphite reactor in Yongbyon.China’s emergency preparedness for transnational emergency due to its nuclear accident should focuse on local food and trade restrictions.
