Consistency in accident analyses in DOE safety, environmental, and emergency planning documents
A consistency review of accident analyses in US Department of Energy (DOE) safety, environmental, and emergency planning documents is presented. The range of and key differences in driving assumptions used in accident definition and frequency assessment, radiological source term generation, and atmospheric transport and fate modeling across recent environmental impact statements (EISs) and emergency planning documents and the effects of these differences on results are summarized. Considerable variation in both the assumptions and the underlying level of conservatism is shown to exist. Recommendations are made for source term generation and assumed meteorological conditions to reduce inconsistencies without being overly prescriptive. Recommendations also are made to improve consistency in assessing the frequencies of various generic accident sequences traditionally analyzed in EIS and emergency planning documents. All recommendations are shown to be consistent with currently applicable DOE guidance.
