摘要
本文根据秦山核电厂第一次 (没有实施氧化运行 )和实施氧化运行的第二、三、四次换料大修期间主冷却剂放射性水平、现场辐射水平的测量结果的分析 ,就停堆过程中实施氧化运行对降低大修现场辐射水平的效果进行分析研究。分析表明 ,在停堆过程中实施氧化运行能有效地降低辐射源项 ,降低大修现场的辐射水平 ,是降低大修集体剂量、实现辐射防护最优化的有效手段之一。
The effects of reducing radiation level with primary circuit oxygenation operation during cold shutdown were described in this paper. Based on the results of radiological analysis of primary coolant, radiation measurement on workplace during the 1 st outage (without oxygenation operation) and the 2 nd , 3 rd , and 4 th (with oxygenation operation) in Qinshan NPP. The effects of oxygention operation on reduction of radiation level in working area were analyzed. It shows that oxygenation operation during cold shutdown process can reduce radioactive source term, radiation level in working area and collective dose effectively. It is one of the ways to carry out the ALARA. (
