研究干预水平和气象条件对核事故早期应急决策的影响。利用 L agrangian烟团模型 RIMPUFF预测 PWR6事故时相应于稳定和不稳定气象条件下的剂量分布 ;考虑了由国家核安全局和国家环保局联合发布的安全导则《核事故辐射应急时对公众防护的干预原则和水平》(HAF0 70 3/NEPA90 0 2 )中的干预水平和 IAEA新推荐的干预水平。PWR6事故条件下 ,采用各种实时气象条件的计算结果表明 ,隐蔽和服稳定碘的区域的半径为 10 km范围 ,撤离区的半径为 5 km。两种干预水平在应急行动范围方面的差异主要体现在隐蔽区域上 ,后者给出的隐蔽区域比前者给出的区域小很多。干预水平与气象条件对早期应急决策的影响是很大的
The impact of intervention level and meteorological conditions on early emergency decision-making in nuclear accidents was studied. The L agrangian model RIMPUFF was used to predict the dose distribution under steady and unstable meteorological conditions in the case of PWR6 accident. Consideration was given to the safety guidelines jointly issued by the NNSA and the State Environmental Protection Agency Interventions and Levels of Interventions "(HAF0 70 3 / NEPA90 0 2) and the newly recommended level of intervention by the IAEA. Under the PWR6 accident condition, the calculation results using various real-time meteorological conditions show that the radius of the concealed and stable iodine region is 10 km and the evacuation zone has a radius of 5 km. The difference between the two intervention levels in the scope of emergency action is mainly reflected in the hidden area, which gives the hidden area is much smaller than the area given by the former. The impact of intervention level and meteorological conditions on early emergency decision-making is significant
