AP1000一回路泄漏率试验介绍与分析

AP1000 Reactor Coolant System Leak Rate Test Introduction and Analysis

AP1000技术规格书中对一回路泄漏率有严格限制并要求能监测一回路泄漏率，以保证一回路的运行泄漏不会危及反应堆安全。本文介绍了AP1000一回路运行泄漏的监测手段、测量方法以及安全壳内非一回路泄漏的识别，分析了一回路泄漏率试验存在的问题及应对措施，同时与秦山二期M310泄漏率试验进行对比，总结了AP1000泄漏率试验的优缺点。

There is a strict limit for RCS leak rate in Technical Specification of AP1000 and the T.S. also required monitoring the leak rate to ensure the leakage of RCS will not endanger reactor safety. This paper makes a particular introduction of methods for monitoring and measuring the RCS leakage, identifying the non-RCS leakage inside the containment, analysis of the existing issues of RCS leak rate test and solutions are also presented. In addition, this paper gives the comparison with M310 and summarization of the characteristics of AP1000 leak rate test.
