中国原子能科学研究院的游泳池反应堆SPR已运行了24年。分析的主要目的是估计堆在今后继续运行中的总体安全性。整个分析是按PSA导则要求进行的,特别关注的内容是:(1)熟识堆的安全有关系统和运行经验;(2)检查和检测堆运行设备的状态,包括那些平时很少运行但对缓解事故有重要作用的设备;(3)为事故序列分析建立成功准则;(4)利用简单的马尔科夫过程分析冗余备用系统;(5)详细考虑人因失误,因为人因在SPR安全运行中起重要作用;(6)发展EXSETS程序来加强一级PSA计算,包括不确定性、恢复、重要度和灵敏度计算;(7)考虑事故后的恢复操作,对支持系统和恢复操作特别重要。该分析能改进管理员 和操纵员的培训。由于SPR的数据收集工作仍在进行中,更加特定的计算待后进行。
The China Institute of Atomic Energy’s pool reactor SPR has been in operation for 24 years. The main purpose of the analysis is to estimate the overall safety of the heap for continued operation in the future. The entire analysis was conducted in accordance with the PSA Guidelines, with particular focus on: (1) Familiarity with the safety and safety related systems and operational experience with the heap; (2) Inspection and testing of the status of the heap and running equipment, including those that are rarely used (3) Establishing success criteria for accident sequence analysis; (4) Analyzing redundant backup systems using simple Markov processes; (5) Taking into account human error in detail, (6) development of the EXSETS program to enhance the level 1 PSA calculations, including uncertainty, recovery, importance and sensitivity calculations; (7) taking into account post-incident recovery operations is particularly important for support systems and recovery operations . This analysis can improve the training of administrators and operators. As SPR data collection is still in progress, more specific calculations are pending.
