Abstract

Results are presented from calculating the activities of fission products and actinides for the mean fuel burnup of the Belarusian Nuclear Power Plant (Belarusian NPP) (55.6 MW d t–1 U). Rates of the loss of total activity are obtained for the spent nuclear fuel (referred to below as SNF) depending on the period of storage. Calculation studies of the radiotoxicity characteristics of spent WWER-1200 nuclear fuel allows the listing of radionuclides that are potential radiation hazard at different stages of SNF management at the Belarusian NPP. The results are important when making decisions on the environmentally acceptable option for spent nuclear fuel management presented in the Belarusian NPP’s Strategy of SNF Management.

白俄罗斯核电厂长期处理废核燃料过程中辐照的WWER-1200燃料的辐射毒性及其活性损失的计算研究

摘要

通过计算裂变产物和act系元素的活动,得出了白俄罗斯核电厂(白俄罗斯NPP)(55.6 MW dt –1 U)的平均燃料消耗量的结果。取决于储存时间,可以获得乏核燃料(以下简称SNF)总活性损失的速率。通过对废WWER-1200核燃料的放射毒性特性进行计算研究,可以列出白俄罗斯核电厂在SNF管理的不同阶段可能产生辐射危害的放射性核素。在就白俄罗斯核电厂的SNF管理策略中提出的乏核燃料管理的环境可接受方案做出决策时,结果非常重要。
