针对核电厂故障停机会造成较大经济损失、核岛外部分设备可并行维修的特点，对核岛外设备机会维修策略进行了研究，提出了基于设备自身最优维修间隔的机会维修控制策略，利用蒙特卡罗仿真方法给出了在给定时间间隔内求取最优维修间隔和机会维修系数的仿真算法，并通过算例验证了机会维修策略对提高系统运行可用性的有效性。
Considering the characteristics of that the failure downtime of nuclear power plant will lead great economic loss and that the partial equipment outside the nuclear island can be maintained parallelly,the opportunity maintenance strategy for equipment outside the nuclear island is studied.An opportunity maintenance control strategy is put forward based on the optimal maintenance interval of equipment itself.The simulation algorithm for solving optimal maintenance interval and opportunity maintenance coefficient is offered using Monte Carlo simulation method with maximal operational availability during given time interval.The validity of the opportunity maintenance strategy for advancing system operational availability is proved by an example.
