EPR首堆机组调试监督及经验浅谈

Commissioning Supervision and Experience Feedback of First EPR Reactor Unit

根据三代堆型EPR机组的特点,调试监督人员采用不同的监督检查方式,对EPR首堆机组——台山核电厂1号机组的调试全过程进行了审评监督和现场见证,保质保量地完成调试监督任务。在日常核安全检查的基础上,调试监督人员对EPR首堆开展了6次调试相关的控制点检查,并选取78项调试试验进行专项监督,其中首堆试验17项,确保了重要调试试验得到过程监督和结果见证。本文从调试监督项目选取、审评监督一体化机制、严格先决条件审查和高风险试验严格管控等9个方面对EPR首堆的调试监督经验进行了总结,形成了可借鉴的监督经验和模式,同时对EPR首堆机组后续运行提出了监督意见和建议。

According to the characteristics of EPR units,commissioning inspectors adopt various supervision and inspection methods to review,supervise and witness the whole process of commissioning of Taishan nuclear power plant unit 1,which is the EPR first reactor unit.The task of commissioning supervision was completed with high quality and quantity.On the basis of daily nuclear safety inspection,commissioning inspectors carried out six hold point inspections of commissioning of EPR first reactor,and selected 78 commissioning tests for special supervision,including 17 first reactor tests,to ensure that important commissioning tests are supervised in process and witnessed in results.This paper summarizes the commissioning supervision experience of EPR first reactor from nine aspects,such as the selection of commissioning supervision items,the integration mechanism of review and supervision,the strict review of preconditions,and the strict control of high-risk tests,forming the supervision experience and mode that can be refer for another new type rector.Finally,the supervision opinions and suggestions for the subsequent operation of EPR first reactor unit were proposed.
