Abstract

Since November 2016, the new Regulatory Guideline NP 306.2.208-2016 “Requirements for Seismic Resistance Design and for Evaluation of Seismic Safety of Ukrainian NPPs” [1] has been in force in Ukraine. This Guideline was developed to improve requirements for NPP site seismic hazard assessment, NPP seismic resistance design and assessment/review of Ukrainian NPP seismic safety. Energoatom developed the Organizational and Technical Measures for Implementation of NP 306.2.208-2016 [2] approved by State Nuclear Regulatory Inspectorate of Ukraine to perform NP 306.2.208-2016 [1] requirements. The paper considers the status of Energoatom in implementation of the main organizational and technical measures [2] on increasing seismic resistance of Ukrainian NPP units according to NP 306.2.208-2016 [1]. In particular, these measures are the following: specification of NPP site seismicity considering results of new studies; introduction of changes into classification (seismic categorization) of systems and components; analysis of necessity to consider additional load combinations with seismic loads, specification of assessing seismic resistance of structures, systems and components; seismic probabilistic safety assessment of NPP units.

乌克兰核电站抗震评估使用法规指南NP 306.2.208-2016的规定

自2016年11月以来，新的监管指南NP 306.2.208-2016“乌克兰核电站抗震设计和抗震安全评估要求”[1]已在乌克兰生效。制定本指南是为了改进对核电厂现场地震危害评估、核电厂抗震设计和乌克兰核电厂地震安全评估/审查的要求。Energoatom制定了经乌克兰国家核监管监察局批准的NP 306.2.208-2016[1]实施组织和技术措施，以执行NP 306.2.208-2016[1]要求。本文考虑了Energoatom在实施np306.2.208 -2016[1]的主要组织和技术措施[2]方面的状况，以提高乌克兰核电站机组的抗震能力。具体而言，这些措施包括:考虑新研究结果，规范核电站场址地震活动性;介绍系统和部件分类(地震分类)的变化;分析考虑附加荷载组合与地震荷载的必要性，评估结构、系统和构件抗震性能的规范;核电厂机组地震概率安全评价。
