AP1000核电厂基于精细化理念的设备鉴定管控体系构建与实施

Establishment and Implementation of Equipment Qualification Management System Based on Refined Concept in AP1000 Nuclear Power Plant

针对AP1000核电厂运行期间设备鉴定有效维持工作的规范化与精细化问题,结合三门核电厂设备鉴定管控工作实践,分析了AP1000核电厂机组运行阶段设备鉴定维持管控现状,阐述了AP1000核电厂设备鉴定精细化管控体系构建及实施。通过系统构建了包括设备鉴定大纲管理、清单管控、业务程序管控、多专业协同保障等要素在内的“1+2+3”精细化管控体系,并实施鉴定设备分类管控策略、建立延寿评估流程、构建运行限制监督机制等措施,规范实施AP1000核电厂设备鉴定精细化管理。该体系的实践取得了显著的经济效益和社会效益,为核电企业开展设备鉴定有效维持精细化管控积累了经验。研究成果对于推动核电设备鉴定管控工作规范化具有重要意义,为核电事业的高质量发展提供了有力支撑。

Aiming at the standardization and refinement of the effective maintenance of equipment qualification during the operation of AP1000 nuclear power plant,this paper analyzes the status of equipment qualification control in the operation phase of AP1000 nuclear power plant,expounds the establishment and implementation of the refined equipment qualification management system in AP1000 nuclear power plant based on the practice of equipment qualification management of Sanmen nuclear power plant.The“1+2+3”refined management and control system,including equipment appraisal outline management,lists control,procedure control,multi-professional cooperation guarantee and other elements,has been systematically established,and measures such as the classified management and control strategy of appraisal equipment,the establishment of life extension assessment process,and the construction of operation restriction supervision mechanism have been implemented to standardize the implementation of the refined management of equipment qualification of AP1000 nuclear power plant.The practice of this system has obtained remarkable economic and social benefits,and accumulated experience for nuclear power enterprises to carry out equipment qualification and effectively maintain fine control.The research results are of great significance for promoting the normalized control of nuclear power equipment qualification,and provide strong support for the high-quality development of nuclear power industry.
