Abstract

A study of six alternatives for the definition of large radiological releases used to estimate the frequency of large release following postulated severe accidents has been performed. Some of these alternatives are solely based on the release thresholds, and can be readily calculated using the results of the level-2 Probabilistic Safety Assessments (PSAs). On the other hand, calculation of other alternative definitions (e.g., those involving estimation of ex-plant consequences) requires appropriate estimation of release radiological activities and/or other consequence measures (e.g., early fatalities, ground contamination, dose, etc.).
