摘要
中核运行三厂曾发生两次因为仪表管线泄漏导致的停堆事件。仪表管线在重水堆核电站中的作用是工艺参数的引压、取样,是属于压力边界的一部分。重水从仪表管线破损处向安全壳内泄漏,不但导致重水泄漏损失,还会导致安全壳内氚剂量上升,增加检修难度。所以,保证仪表管线的完整性,是重水堆电站需要关注的问题。
Early in 2013, the reactor for CNNP has been shutdown cause by sample line twice. In Candu reactor, the sample line was used for parameter measurement, it also belong to the pressure boundary. The leakage on sample line will lost heavy water, and tritium concentration in reactor building will be raised. The sample line need be radically concerned.
