压水堆机组调试启动停机停堆事件研究与探索

Research and Exploration of Pressurized Water Reactor Unit Commissioning,Start-up and Shutdown Events

根据24台压水堆(PWR)机组工程调试实践,系统试验的深度与充分性会直接影响机组首次启动试验的一次成功率及连续性。因此,有必要从系统维度对以往压水堆机组启动非预期停机停堆事件进行深入分析、探索、总结,为后续机组启动提供经验参考和精准的改进措施。通过重点梳理仪控系统相关启动事件的原因分析,借鉴世界核能运行者协会成熟的机组运行管理理念,创新性地以核电工程活动视角进行解构,准确识别出仪控调试专业领域短板与弱项;同时,结合工程实践与仪控调试技术能力现状,探索性、针对性地提出改进措施。该项研究与探索可为压水堆仪控调试领域的质量提升提供重要参考与借鉴,系统性地增强学习成长效应,持续助力调试质量与效率。

According to the engineering commissioning practice of 24 pressurized water reactor(PWR)units,the depth and adequacy of system test will directly affect the first success rate and continuity of the unit's first start-up test.Therefore,from the system dimension,it is necessary to conduct in-depth analysis,exploration and summary of the non-expected shutdown events of PWR units in the past,so as to provide experience reference and accurate improvement measures for subsequent unit start-up.By focusing on the analysis of the causes of the start-up events related to the instrument and control system and drawing on the mature unit operation management philosophy of the World Association of Nuclear Energy Operators,creatively deconstruct from the perspective of nuclear power engineering activities,and accurately identifies the weaknesses in the field of instrument and control debugging.At the same time,combined with the engineering practice and instrument control debugging technical ability status,exploratory and targeted improvement measures are put forward.The research and exploration can provide an important reference for the quality improvement in the field of PWR instrument control and commissioning,system atically enhance the learning and growth effect,and continuously help the quality and efficiency of commissioning.
