东电因流量偏低警报暂停福岛核处理水排放

东京电力公司控股公司周六暂停了福岛第一核电站处理后放射性水的排放,原因是流量偏低警报触发了自动停机。

该公司表示,海水稀释泵的紧急切断阀在两根厂内输电线因雷雨天气出现瞬间停电导致水流下降后关闭。当时该地区报告有雷暴天气。

辐射监测系统未检测到异常,水泵功能正常。东电表示,在确认系统安全后,将恢复处理水的排放。

周三也曾响起同样的警报,导致排放暂停。运营商当时更换了水箱出口的一个阀门,并于次日恢复了排放。

自2011年3月地震和海啸发生以来,随着熔化的核燃料持续冷却,福岛核电站积聚了大量放射性水。这些水在稀释并排入太平洋之前,已经过处理以去除除氚以外的大部分放射性核素。
