Abstract

Abstract:

The RELAP5 model was recreated according to the latest design of the CN HCCB TBS, and two design basis accidents, in-vessel loss of coolant accident (LOCA) and loss of flow accident (LOFA), were investigated. According to the results, the safety of CN HCCB TBS is guaranteed during the two accident situations, and the thermal-hydraulic transient analysis can give the information about the TBM safety relevant behavior in accidents, suggesting the necessary protection system and their responding time.

Key words: CN HCCB TBS, RELAP 5, LOFA, In-vessel LOCA

摘要：

基于CN HCCB TBS 的最新设计，用RELAP 5 软件对失流事故(LOFA)和真空室内失冷事故(In-vessel LOCA)这两种假设基本事故进行了分析。结果表明，CN HCCB TBS 在这两种事故工况下的安全性是有保证的，并且热工水力学瞬态分析能给出有关发生事故时TBM 安全性相关性能的信息，从而提出了所需要的各种安全保护系统及其动作的时间。
