核燃料循环设施抗震设防要求的探讨

Discussion on Seismic Fortification Requirements for Nuclear Fuel Cycle Facility

简述了国内外核燃料循环设施抗震设防相关标准规范要求,以设施存在的潜在风险作为确定抗震设防要求的出发点,在充分考虑核燃料循环设施特点的基础上,探讨了抗震设防的主要考虑因素。结合我国核设施抗震设防实践,提出了典型核燃料循环设施的抗震设防要求建议,并与国外相应抗震设防要求进行对比,旨在形成统一的、较为明确的抗震设防尺度,供核燃料循环设施设计和审评时参考。

The relevant seismic fortification standards and requirements on both domestic and international nuclear fuel cycle facilities were briefly described in this paper. Taking the facility potential risk as the starting point of seismic fortification and fully considering the specific characteristics of nuclear fuel cycle facilities extensively, this paper discussed the key factors of seismic fortification. In addition, taking the seismic fortification practice in domestic nuclear facilities into account, the requirements and suggestions on typical nuclear fuel cycle facility were made, and the international relevant seismic fortification requirements were compared for the purpose of reaching a clear unified agreement on seismic fortification criterion, to offer suggestions for nuclear fuel cycle facility design and evaluation to some extent. © 2016, Editorial Board of Journal of Nuclear Power Engineering.
