智通财经5月16日电,国际原子能机构总干事格罗西15日表示,自5月7日以来,扎波罗热核电站仅依靠 一条输电线路供电。当前的俄乌冲突阻碍了恢复备用线路。根据国际原子能机构的数据,仅剩的330千 伏备用电线于5月7日被切断。 国际原子能机构总干事:扎波罗热核电站的核安全仍不稳定 ...
已安全运行600堆年!揭秘核电站抗震防灾“硬核”措施(视频)

中国经济网北京4月29日讯(记者 杨秀峰 李冬阳) 今年是国家安全法颁布施行10周年。核安全是国家安全 的重要组成部分,是核事业发展的生命线。截至目前,我国大陆地区核电机组已安全运行600多堆年, 一直保持良好安全业绩。 在设计阶段,根据法规标准的要求,核电厂与核安全有关的设备和构筑物不仅要能够抵御相应等级的地 震,还要具有一定的安全裕度。例如,我国福建福清核电厂5、6号机组采用华龙一号堆型,其抗震设计 设防水平是0.3个重力加速度,远高于其厂址区基本烈度0.1个重力加速度。此外,核电厂抵御各类自然 灾害的要求极高,必须对暴雨、河流洪水、风暴潮、海啸在内的各类水文灾害进行评价。一般情况下, 核电厂暴雨灾害防护设计基准是超过万年一遇的"可能最大降水",河流洪水灾害防护设计基准是超过万 年一遇"可能最大洪水"等,远远不是"千年等一回"。 侯英东介绍,为确保核电厂安全稳定运行,我国核电厂均配备了地震监测系统,可用于提供报警,并制 定了相应的规程,根据相关报警信号保守地采用反应堆降功率或停堆、核查机组状态、启动应急响应等 措施。 "目前我国核电厂厂址均远离发震构造,附近不存在能动断层,地震危害性较低,并充分考虑了暴雨 ...
