对钠冷快堆安全壳设计的探讨

Discussion on the Design of LMFBR Containment

安全壳是在核电厂纵深防御原则中的最后一道屏障,是保证核电厂在严重事故条件下安全的重要设施。由于钠冷快堆的固有安全性,其安全壳与压水堆安全壳的功能和作用相同。通过对钠冷快堆安全壳的设计分析,阐述了其在设计基准、结构设计上区别于压水堆安全壳的特点,为确定钠冷快堆安全壳设计和审评原则做出了有益的探索。

The containment is the last barrier for the Principles of Nuclear Power Plant Safety Defense in Depth, and the significant facility to ensure NPP＇ s safety in case of serious accident. Since sodium cooled fast reactor （or called as LMFBR） has inherent safety feature, the function of LMFBR containment is the similar as PWR＇ s. LMFBR containment characteristics distinguished from PWR containment in design bases and structure are elaborated in this article. Beneficial attempts are made to establish some design and review principles for LMFBR containment.
