摘要
按照现有的设计和遵循的相关规程,秦山核电厂事故工况下主给水系统隔离后不能恢复运行,对核电厂总的堆芯损伤频率的贡献较大。本文应用PSA的模型及结果,阐明主给水系统恢复运行的必要性。探讨恢复主给水系统运行的可能性,给出了相关可行性方案,以便抛砖引玉,展开对秦山核电厂事故后恢复主给水系统运行的专题研究。
According to the current design and relative procedures in QNPP, the main feed-water system can not be restored after its isolating under accident conditions, and thus there will be a larger contribution to the total core damage frequency of QNPP. In this paper, the necessity of the main feed-water recovery is illustrated with the help of a Probability Safety Assessment （PSA） model and its quantitative results. In order to initiate a widely discussion on topical studies of main feed-water recovery after accident of QNPP, the possibility of recovery is investigate and some suggestions are put forward.
