秦山核电站是我国首座自行设计、建造的30万kW压水堆核电站。它由核岛(一回路系统)、常规岛(二回路系统)和辅助厂房组成。 根据核电建设规定,核岛中核安全级部件必须按在役检查大纲的要求,在核电站停堆换料检修期间进行在役检查,而在役检查大纲中并无常规岛非核安全级部件的检查内容和要求,但根据火电站与核电站常规岛相似的汽轮发电机金属监督检查的经验,核电站常规岛中的非核级部件也应在制定常规岛金属监督检查大纲的基础上与核级部件一样,定期作金属监督检查。
Qinshan Nuclear Power Station is China’s first self-designed, built 300000 kW PWR nuclear power station. It consists of a nuclear island (primary loop system), a conventional island (secondary loop system), and an auxiliary plant. According to the nuclear power construction regulations, the nuclear island nuclear safety level components must be in line with the requirements of the inspection outline in the nuclear power plant during the inspection heap refueling overhaul, and in-service inspection program there is no conventional island non-nuclear-safety components inspection content However, based on the experience of metal supervisory inspection of turbogenerators similar to conventional power stations in nuclear power plants, the non-nuclear components in conventional islands of nuclear power plants should be the same as those of nuclear components based on the routine island metal supervision and inspection program. Regular metal supervision and inspection.
