秦山核电厂安全壳系统B、C类密封性试验

PRIMARY REACTOR CONTAINMENT LEAKAGE TESTS (B & C TYPES) FOR QINSHAN NUCLEAR POWER PLANT

叙述了秦山核电厂安全壳系统B、C类密封性能试验概况,主要包括试验范围、泄漏率分配、试验结果和总体评价等。

Primary reactor containment leakage testing (B & C types) for Qinshan Nuclear Power Plant is described in this paper. Type B tests include piping and electrical penetrations, air lock door seals and fuel transport canal seal Type C tests relate to the measurement of containment isolation valve leakage rate. The test methods, allowable leakage rates, test results and overall evaluations are discussed in detail to some extent.
