摘要：

The technical concept and guidance of preventive maintenance (PM) program optimization dominated by equipment classification are put forward, and the optimization technical route and cases of PM program of C/S/E/R equipment at all levels are given. It has been applied to the lean program of PM program of several CPR1000 nuclear power units in China from 2018 to 2020, which improved and strengthened the PM program of key important equipment and reduced excessive maintenance, so that the maintenance resources can be allocated reasonably. By the end of 2020, the total value of the PM program equivalent of 16 CPR1000 units has been reduced by more than 20%. It is conservatively estimated that the maintenance cost savings of PM is more than 50 million yuan. Practice has proved that the application of equipment classification based PM program optimization technology can not only ensure the reliability maintenance level of key and important equipment, but also effectively reduce the operation and maintenance costs of nuclear power units, which can be used as a reference for other nuclear power plants to optimize PM program. © 2022 Yuan Zi Neng Chuban She.
