目的探讨核事故场外应急计划区的分类和设置。方法根据国际原子能机构相关标准和技术报告中的建议以及国内相关标准和预案,对我国核事故场外应急计划区的设置进行分析。结果国际原子能机构的最新技术手册增加和细化了对核事故场外应急计划区设置的要求,这些调整是基于新的防护行动剂量通用准则、更加完善的模拟计算结果以及以往核事故应急中的实际经验,国内相关标准还需要进一步完善。结论建议根据国际原子能机构的相关标准和报告并结合我国的具体情况,对国内标准进行修订。
Objective To explore the classification and setting of emergency planning area for off-site nuclear accidents. Methods According to the recommendations of International Atomic Energy Agency standards and technical reports, as well as relevant national standards and plans, the settings of off-site emergency planning areas for nuclear accidents in our country were analyzed. Results The latest IAEA technical manuals added and refined the requirements for the setting up of off-site emergency planning zones for nuclear accidents based on the new generic guidelines for dose protection, improved simulation results and previous nuclear accident responses Practical experience, domestic standards also need to be further improved. Conclusion It is suggested that the national standards should be revised in accordance with the relevant IAEA standards and reports and with the specific conditions in our country.
