The importance of performing Level 3 probabilistic safety assessments (PSA) along with a generalinterest in assessing multi-unit risk has been sharply increasing after the Fukushima Daiichi nuclearpower plant (NPP) accident. However, relatively few studies on multi-unit Level 3 PSA have beenperformed to date, reflecting limited scenarios of multi-unit accidents with higher priority. The majordifficulty to carry out a multi-unit Level 3 PSA lies in the exponentially increasing number of multiunitaccident combinations, as different source terms can be released from each NPP unit; indeed,building consequence models for the astronomical number of accident scenarios is simply impractical. In this study, a new approach has been developed that employs the look-up table method to coverevery multi-unit accident scenario. Consequence results for each scenario can be found on the table,established with a practical amount of effort, and can be matched to the frequency of the scenario. Preliminary application to a six-unit NPP site was carried out, where it was found that the differencebetween full-coverage and cut-off cases could be considerably high and therefore influence the totalrisk. Additional studies should be performed to fine tune the details and overcome the limitations ofthe approach.
