5MW低功率堆运行的环境影响

Environmental Impacts of Operation for 5MW Low Power Reactor

本文评价了5MW 低功率堆(5MW LPR)放射性流出物对环境的影响。应用厂址周围的人口与食谱调查资料,以及计算模式和参数,估算了该堆在正常运行时,厂址边界1km 处的最大个人有效剂量当量为8.89×10^(-8)Sv·a^(-1),80km 范围内的集体有效剂量当量为7.17×10^(-4)人·Sv·a^(-1)。调查数据说明,该堆正常运行和假想事故期间对本地区的环境影响都是可以接受的。

Based on the population and diet information around the sitealong with the calculating models and parameters,the individualand collective effective dose equivalent are estimated from radio-active materials released.The maximum individual effective doseequivalent around site for 1km is 8.89×10^(-8)Sv·a^(-1),the collectiveeffective dose equivalent around site for 80km is 7.17×10^(-4) men·Sv·a^(-1).Collected data explain that the environmental impacts un-der normal and assumed accidental condition for 5MW LPR areall acceptable.
