核电厂水工构筑物的老化评估

Aging Review of Hydraulic Structures in Nuclear Power Plant

核电厂水工构筑物是为核安全相关的系统、设备和部件提供防水淹屏障以及冷却水的重要构筑物,在秦山核电厂运行许可证延续(OLE)期间纳入了评估审查的范围。针对核电厂水工构筑物,本次OLE项目确定了核电厂水工构筑物的管理范围、老化效应,开展了老化管理审查(AMR)和水下检查活动,掌握了水工构筑物的实际服役状态,证明了水工构筑物可继续在核电厂延续运行期间执行其预期功能。

Hydraulic structures of the nuclear power plant are important structures that provide water-flooding barrier and cooling water for nuclear safety related systems,equipment and components,and have been included in the scope of assessment and review during the Operation License Extension(OLE)of Qinshan Nuclear Power Plant.Aiming at the hydraulic structures of nuclear power plants,this OLE project determines the management scope and aging effect of hydraulic structures of nuclear power plants,carries out aging management review(AMR)and underwater inspection activities,and grasps the actual service status of hydraulic structures,which proves that hydraulic structures can continue to perform their expected functions during the extended operation of nuclear power plants.
