摘　　要：NHR200-Ⅱ型供热堆是具有固有安全性的一体化模块式核反应堆,其设计上的安全特性保证了不会发生堆芯放射性物质的大规模泄漏,在技术上具备简化场外应急的可行性。本文在调研国内外先进反应堆在应急准备方面的研究成果基础上,参照国内对于小型核反应堆最新的监管要求,针对某厂址条件选取保守的超设计基准事故进行了剂量测算,论证了应急计划区设置在场区边界的可行性,同时提出了实施场外应急简化的建议。NHR200-Ⅱheating reactor is an integrated modular nuclear reactor with inherent safety,its design safety characteristics ensure that no large-scale leakage of core radioactive materials,making it technologically feasible to simplify the off-site emergency plan.Based on the research results of advanced reactors at home and abroad in emergency preparedness and the latest domestic regulatory requirements for small nuclear reactors,this paper calculates the dose consequences of a conservative BDBA for a certain plant site condition,demonstrates the feasibility of setting the emergency planning zone on the boundary of the plant,and puts forward some suggestions for the simplification of the off-site emergency plan.

关 键 词：核供热堆 应急计划区 应急预案简化
