Main Control Room Renewal Technology Research & Planning of Qinshan Nuclear Power Plant
-
摘要: 基于运行许可延续(OLE)的需求,为确保主控制室与应急控制室(简称主控室和应控室)的设计及设备符合国家核安全相关法规及标准要求,通过对秦山核电厂主控室及应控室的盘台现状、人机接口进行调查和分析,对盘台结构、设备改进及人机接口再设计进行了研究,提出了主控室和应控室整体更新的解决思路并开展了可行性论证,策划了总体设计更新方案、验证流程和实施管控方法。工程实践及运行业绩表明本研究方法是有效的,可为核电机组OLE研究提供指导。Abstract: Based on the requirements of Operation License Extension (OLE) and ensuring that the design and equipment of the main control room and emergency control room (referred to as the main control room and the emergency control room) comply with the relevant national nuclear safety regulations and standards, based on the investigation and analysis of the status quo of panels and consoles and man-machine interfaces of the main control room and the emergency control room in Qinshan Nuclear Power Plant, the structures of the panels and consoles, the improvement of equipment and the redesign of the man-machine interface are studied. The solution of the overall renewal of the main control room and the emergency control room is put forward and the feasibility demonstration is carried out. Methods for updating the overall design scheme, validating the process and implementing the controls are planned. The engineering practice and operation performance show that this research method is effective and can provide guidance for OLE research of nuclear power units.

表 1 秦山核电厂主控室更新应对策略比较
Table 1. Strategy Comparison of Main Control Room Update of Qinshan Nuclear Power Plant
策略 盘台加固及部分设备换型 全数字化盘台 盘台及设备整体更新 特点 旧盘台加固,局部改造设备 重新设计,实现全数字化的主控室和应控室 全面更新盘台、盘台基础和设备,控制系统数字化并重新架构 优点 无需制造新盘台;
尽可能利用旧设备符合最新设计及设备理念;
简化人机接口;
系统化考虑核电厂设备选型保留传统的人机接口风格;
全面实现控制系统数字化升级;
主控室主体框架和控制逻辑不变;
根据功能块考虑设备选型;
增加核电厂人机接口设备冗余度风险 资料不全,设计依据不足;
盘台基础弱项处理困难;
新方案反复修改及论证;
工程量和工期难以预估构筑物面临重大结构改变;
主控室和应控室控制方式彻
底改变;
工程量和工期超预期盘台进主控室的运输通道受限;
变更范围超出预期;
施工工期超出预期应对措施 设计修改或再设计;
增加预算;
延长施工期并推迟施工设计修改或再设计;
增加预算;
延长施工期并推迟施工;
操纵员重新取证培训构筑物局部结构修改;
分阶段实施仪表整改;
协调项目管控,工期合理范围波动结论 存在安全和经济双重风险、工期不可控,盘台设备面临再改造的需求 存在安全和经济双重风险,操纵员需要重新取证,收益与预期不符 解决盘台及设备弱项,具备运行许可延续条件,费用预算合理,改造总体可控 -
