研究堆运行许可证有效期延续申请审查策略

生态环境部第8号令《核动力厂、研究堆和核燃料循环设施安全许可程序规定》对核动力厂、研究堆和核燃料循环设施运行许可证件延续事项作出了新的规定。为推动我国研究堆老化管理标准体系建立，分析了我国研究堆延寿审查策略发展历程，结合高通量工程试验堆等研究堆运行许可证有效期延续申请审查工作中的几个关键问题，提出了以定期安全审查为主、重点依据老化管理并兼顾技术规格书审查及差异性审查的审查策略，研究成果为我国研究堆老化管理法规标准的建立提供了实践经验及理论指导依据。 

Review Strategy of Application for Extension of Validity Period of Operation License for Research Reactor

The Ministry of Ecology and Environment Order No. 8 "Regulations on Safety Permit Procedures for Nuclear Power Plants, Research Reactors and Nuclear Fuel Cycle Facilities" (hereinafter referred to as the "Regulations") has made new clear provisions on the extension of operation licenses for nuclear power plants, research reactors and nuclear fuel cycle facilities. In order to promote the establishment of the aging management standard system of research reactors in China, the development history of life extension review strategy of research reactors in China is analyzed in this paper. Combined with several key issues in the review of the application for extension of the validity period of the operation license of research reactors such as high-flux engineering test reactor, the review strategy is proposed, which gives priority to periodic safety review, focuses on aging management and takes into account the review of technical specifications and differences. The research results provide practical experience and theoretical guidance for the establishment of regulations and standards for research reactor aging management in China.
