Aging and Life Management Methods of Pressurizer based on PDCA Cycle in nuclear power station

The Pressurizer is important equipment in PWR nuclear power station. There is only one Pressurizer, which adjust and keep pressure stable, overall the One Loop System. It is very important for safe operation of nuclear power station to keep integrity of Pressurizer. To carry out the work of aging and life management of Pressurizer more effectively and ensure the Pressurizer run safe and stably, this paper does research on Aging and Life Management Methods of Pressurizer. On the basis of PDCA Cycle, this paper realize the management of leading principles to aging management, operation control, checking, monitoring, evaluation and program of lifetime maintenance.
