摘要

摘要: 为促进国际市场开发，中国广核集团有限公司开展了华龙一号核电技术方案英国通用设计审查（GDA）和欧洲用户要求认证（EUR）。核电厂构筑物、系统和设备的结构完整性是国际审查和认证的重点，为适应英国核安全监管和欧洲用户要求，项目团队采用分析法设计理念，以力学分析、试验和论证为关键手段，完成了英国版和欧洲版华龙一号的结构完整性分析评估和设计改进，全面满足了英国核安全监管和欧洲用户要求。通过华龙一号国际审查和认证，研究了结构完整性领域的相关技术要求，总结了审查过程中的实践和思考，可为华龙一号核电技术方案的持续改进和创新提供借鉴。

Abstract: In order to promote the international market development, China General Nuclear Power Group (CGN) has carried out the Generic Design Assessment (GDA) of UK and the European Utility Requirements (EUR) assessment. The structural integrity of the structures, systems and components in nuclear power plant is the focus of international review and certification. In order to meet the requirements of British nuclear safety supervision and EUR, the project team adopted the design concept of analytical method, and completed the structural integrity analysis, evaluation and design improvement of British and European versions of HPR1000 with mechanical analysis, test and demonstration as the key means, which fully met the requirements of British nuclear safety supervision and EUR. Through the HPR1000 international regulatory and certified review, the relevant technical requirements in the field of structural integrity are studied, and the practice and learning in the review process are summarized, which can support the continuous improvement and innovation of HPR1000 technology.
