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 ...
我国建成世界 规模最大辐射环境监测网

原标题:我国建成世界 规模最大辐射环境监测网 科技日报讯 (记者李禾)记者5月12日获悉,生态环境部核设施安全监管司司长李治国在日前举行的新 闻发布会上说,经过多年建设,我国建成世界上规模最大的辐射环境监测网。 辐射环境监测是核安全工作的基础性工作,发挥着"耳目"和"哨兵"的作用。 辐射环境监测网包括全国辐射环境质量监测、重点核设施周围辐射环境监督性监测和核与辐射应急监 测"三张网"。 李治国说,国家级辐射环境质量监测网设立了1835个监测点,覆盖了全国所有地级及以上城市、重要边 境口岸、核设施周边以及其他重要边境地区。各省区市还建设了点位更多的省控网。核电厂等重要核设 施及附近建有监督性监测系统,即以核设施为中心,在核设施周围5公里、10公里、15公里以及15公里 之外的范围内,布设100多个监测点位。这些点位有的是自动监测站,有的是空气、水、土壤等环境采 样点。 "这些监测点位的实时数据获取率稳定在97%以上。"李治国说,从监测数据看,多年来我国辐射环境质 量保持良好。与上世纪80年代天然环境辐射本底调查相比,我国核设施周围辐射环境没有明显变化。 良好、安全的环境离不开有效监管和先进技术。李治国说,我国努 ...
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 ...

同时,中国已形成较为成熟的核安全监管制度,独立有效地开展许可审评、监督执法、监测应急、经验 反馈等监管活动,其中对核电厂实行选址、建造、运行、退役分阶段的核安全许可制度和严格的核安全 技术审查,对反应堆操纵员、核级焊工、无损检验等特殊工作人员实施严控的资质管理。 "核安全容不得一粒沙子",侯英东强调,将核电厂核安全重要活动纳入监管范围,实施严格的全天候驻 厂监督。对弄虚作假和违规操作"零容忍",动真碰硬惩处违法行为。(完) 侯英东说,目前,中国新建机组均采用三代及以上核电技术,AP1000、EPR、"华龙一号""国和一号"、 高温气冷堆等新型核电机组设计安全水平进一步提高。根据世界核电运营者协会(WANO)最新统计,中 国大陆地区核电机组指标82.18%达到优秀值(前1/10),84.79%达到先进值(前1/4),92.07%达到中值(前 1/2),继续保持全球领先水平。 "良好的安全业绩离不开有效的监管,"侯英东说,坚持从高从严的原则,注重接轨国际,参照国际原子 能机构的安全标准,结合中国实际,建立了完善的核动力厂核安全法规标准体系,坚持成熟设计,纵深 防御,考虑各种风险,设置多种安全屏障,强化有效开展核安 ...
