压水堆核电站大修蒸汽发生器气密性堵板装拆工作的辐射风险控制

摘要

As an important task for PWR NPP overhauls, the assembly and disassembly of plug plate of the steam generator primary-side water chamber involves a large risk of both radiation and leakage. The pre-job training, organization and implementation of operation therein, of Fuqing Nuclear Power Co., are presented. Risk control measures taken are then described.%压水堆核电站蒸汽发生器一次侧水室堵板装拆是电站大修中的一项重要工作,具有较大的辐射控制风险及堵板泄漏风险.本文介绍福清核电在堵板使用前的装拆培训及堵板使用期间的组织与实施过程,并介绍防止堵板使用期间发生人员误碰风险所采取的措施及堵板泄漏风险的应对方案.
