反应堆压力容器退役包装屏蔽方案初探北大核心CSCD

为保证核电反应堆压力容器安全退役,本文以国内最早运行的秦山一期反应堆压力容器源项为参考,模拟设计保持压力容器完整和切割压力容器两种包装屏蔽方案,通过估算两种方案下废物体积、包装成本、运输及处置成本,对比分析发现切割压力容器方案更佳。研究成果可为核电站退役工作提供支持。

A preliminary study on packaging and shielding schemes for reactor pressure vessel decommissioning

In order to ensure the safe decommissioning of reactor pressure vessel (RPV), this paper takes Qinshan Phase I RPV as the reference object, stimulates and designs packaging and radiation shielding schemes under the decommissioning plans of keeping RPV intact and dismattling RPV. This paper further compares and analyzes two schemes by estimating the operability, convenience and economy. The results show that the plan of dismantling RPV is more optimal, which could better support decommissioning of nuclear power plant.
