摘要
本研究的目的是利用大气扩散模型,对正在建设中的鲁普尔核电站(NPP)因假想事故而向大气释放放射性核素的剂量进行估计。遵循nuregg -1228,还使用MATLAB开发了通用源术语代码。灵敏度分析的基础是接收的总有效剂量当量(TEDE)对应于不确定输入参数的变化。在稳定条件下,随着风速的变化,灵敏度更高。不同大气稳定性等级下,鲁普尔核电站不同顺风距离下Xe-133的TEDE剂量估计结果。稳定性A级最大距离为0.7 km时的最大TEDE值为6.400 e -06 Sv,不稳定B级最大TEDE值为5.70E-05 Sv。
Radiological safety analysis of Rooppur Nuclear Power Plant site using atmospheric dispersion model
The purpose of this work is to estimate dose received in case of release of radionuclide into the atmosphere from the under-construction Rooppur Nuclear power plant (NPP) due to a hypothetical accident with the help of an atmospheric dispersion model. A generic source term code has also been developed using MATLAB by following NUREG-1228. The sensitivity analysis is based on variation of the received total effective dose equivalent (TEDE) corresponding to the variation of the uncertain input parameters. The sensitivity was seen to be higher at stable conditions with the change of high wind speed. Estimated TEDE dose results for Xe-133 at different downwind distances from Rooppur NPP site in different atmospheric stability classes. The maximum TEDE of 6.40E-06 Sv was estimated at maximum distance of 0.7 km from the site for stability class A, whereas, in case of unstable stability class B, it was 5.70E-05.
