压水堆核电机组不同时刻135I食入、吸入危害分析

Hazard Analysis of 135I inhalation and ingestion in PWR Nuclear Power Units at Different Time

核能作为一个经济、安全且无暖化气体排放的电力来源,受到世界各国的广泛重视。但是1986年的切尔诺贝利和2011年的福岛核泄漏事故,其放射性烟羽对周边环境造成了巨大的影响,针对核电机组源项分析对于核安全和核应急有着重要意义。本文应用美国橡树岭国家实验室开发出来的ORIGEN2软件计算大亚湾商用压水堆核电站的放射性核素的吸入、食入危害问题,通过ORIGEN2软件对M310机组可能产生的泄漏进行源项135I分析,并对其进行放射性吸入、食入危害计算。

Nuclear energy,as an economic,safe and non-heating gas emission power source,has received extensive attention from all over the world.However,theChernobyl accident in 1986 and Fukushima nuclear leak accident in 2011 caused a huge impact on the surrounding environment.The source term analysis of nuclear power units is of great significance for nuclear safety and emergency response.In this paper,ORIGEN2 software developed by Oak Ridge National Laboratory is used to calculate the hazards of radioactive nuclides inhalation and ingestion in Daya Bay Commercial Pressurized Water Reactor Nuclear Power Station.The source term 135 I of the leakage from M310 is analyzed by ORIGEN2 software,and the hazards of radioactive inhalation and ingestion are calculated.
