Maintenance Expense Optimization Method for High Temperature Reactor Equipment Group

The composition of the high-temperature reactor system is relatively complicated. The failure mechanism and degradation process of each component in the system are not the same, and the timing of failure is not the same, resulting it impossible to ensure all components being maintained by preventive planning maintenance. According to the fault correlation, time correlation, functional correlation and structural correlation between components in the multi-component system, the components that meet the maintenance conditions within a certain period of time can be integrated and repaired, which can not only share the fixed cost, but also reduce the downtime. It also increases the overall availability of the equipment.
