摘　　要：针对CAP1400核电站堆外核测探测器组件在反应堆满功率运行条件下,基于热中子灵敏度材料燃耗方程推倒计算公式,分别计算了设计寿命内和满足累积剂量条件下的探测器的燃耗,计算了探测器灵敏度下降1%时对应的寿命。得到NIS探测器30年设计寿命的燃耗计算结果,满足设计要求。可为探测器的研制和核电站运维提供理论指导。The article calculated CAP1400 Reactor Nuclear Instrumentation System Detector Assemblies burn up in the full power,based on the thermal neutron sensitive materials burn up equation turn down the formula,calculated the burn up of the detectors in the design life time,calculated the burn up of the detectors to meet the integral dose requirement,calculated the life of the detectors to the sensibility decrease 1%. The calculation also could provide reference for other neutron detector development and the power plant operation and maintenance.
