压水堆核电厂选址假想事故初步研究

Abstract

Abstract: In this paper, the development of accident for siting of pressurized-water nuclear power plants (NPPs) is briefly described firstly. Postulated conditions of source terms based-on RG 1.183 and RG 1.195 are compared and the accident source terms for AP1000 and CPR1000 NPPs are calculated respectively. Finally, offsite radiological consequences for some specified NPP are evaluated according to the calculated accident source terms. The results show that 1, based-on the RG 1.183 assumptions, the most serious offsite radiological consequences of 2 hours for the AP1000 and CPR1000 NPPs happen during 1.25—3.25 h and 0.7—2.7 h respectively after accident, and 2, in the same based-on the RG 1.183 or RG 1.195, radiological consequences of CPR1000 NPPs is less than that for AP1000 NPPs.

Key words: pressurized-water nuclear power plants, activity release, source term, RG 1.183, RG 1.195
