西安脉冲堆对环境的影响

Impacts of Xi'an Pulse Reactor on Environmental

应用厂址周围的人口与食谱调查资料以及反应堆参数 ,计算了该堆及其同位素生产线在正常运行及事故工况下厂址控制区边界的最大个人有效剂量当量和80km范围内的集体有效剂量当量。计算结果表明 :在正常运行时 ,厂址控制区边界最大个人有效剂量当量为6 0×10 -3mSv/a ,80km范围内的集体有效剂量当量为0 35人·mSv/a。反应堆最大假想事故事故下 ,所致厂址限制区外(500m)公众最大全身有效剂量当量为2 1×10-2mSv ,甲状腺剂量为3 8mSv ;事故持续30天后 ,80km范围内的集体有效剂量当量为0 14人·Sv(全身)和97人·Sv(甲状腺) ;

Based on the population and diet information around the site along with the parameters of reactor,the individual and collectiveeffective dose equivalent are estimated from radioactive materials released The maximum individualeffective dose equivalent around site for 500m is 6 0×10-3mSv/a,the collectiveeffective dose equivalent around site for 80km is 0 35 men·Sv/a Collected data explain that the environmental impacts under normal and assumed accidental condition for Xi'an Pulse Reactor are all acceptable
