摘　　要：通过研究工业领域常用的可靠性指标分配方法,结合新堆的设计特点,确定了适合的可靠性指标分配方法。利用比例组合法和专家打分法将新堆的堆芯损坏频率(CDF)分配到停堆保护系统。通过分配测算,停堆保护系统的可靠性指标达到8.83×10^(-5)即满足安全目标要求。The appropriate reliability index distribution method is determined by researching the existing reliability index methods and combining the design characteristics of the new NPP.The CDF of the new reactor is distributed to the reactor trip protection system by the ratio-composed method and expert evaluation method,and finally we find that the reactor trip protection system meets the safety target requirement when the reliability index reaches 8.83×10^-5.
