摘要
核反应堆专设安全设施的失效率估计是反应堆可靠性数据处理的一项重要工作。通用的需求失效模型在某些反应堆的应用中受到限制。在一般贝叶斯方法的基础上,考虑了备用期内的失效问题,建立了失效率估计的备用失效模型。该模型定义的备用时间可代替后验数据需求次数,在反应堆可靠性数据处理中有一定的实用价值。
Estimations of failure rates engineered safeguards features of nuclear reactors are important jobs for reactor reliability data processing. Yet the application of usual 'failure-on-demand model' in some reactors is restricted. Thus, based on general Bayesian method, standby-failure model for failure rate estimation was deduced in the paper. The model, which was practicable for reliability data processing in some nuclear reactors, considers failures occurring during standby time and only needs to input 'standby time' instead of 'the number of demands'.
