RADIOLOGICAL CONSEQUENCE ANALYSIS UNDER SEVERE ACCIDENT CONDITIONS FOR THE ADVANCED NEUTRON SOURCE REACTOR AT THE OAK-RIDGE-NATIONAL-LABORATORY

This article discusses salient aspects of methodology, assumptions, an d modeling of various features related to radiation exposure and the h ealth consequences from source terms resulting from two conservatively scoped severe accident scenarios. Radiological consequences for a sit e-suitability scenario based on 10 CFR 100 guidelines also are present ed. Consequences arising from severe accidents involving steaming pool s and core-concrete interaction (CCI) events combined with several dif ferent containment configurations are presented Results are presented in the form of mean cumulative values for prompt and latent cancer fat ality estimates and related cumulative, complementary distribution fun ctions as a function of distance from the reactor site. It is shown th at the reactor-site-suitability risk goals are met by a large margin a nd that overall risk is dominated by early containment failure combine d with CCI events.
