Interfacing the output of severe accident analysis with the input of radiological consequence analysis isan important and mandatory procedure at the beginning of Level 3 PSA. Such interfacing between thesevere accident analysis code MELCOR and MACCS, one of the most commonly used consequenceanalysis codes, is relatively tractable since they share the same chemical groups, and the related interfacing software, MelMACCS, has already been developed. However, the linking between MAAP, anotherfrequently used code for severe accident analyses, and MACCS has difficulties because MAAP employs adifferent chemical grouping method than MACCS historically did. More specifically, MAAP groups bychemical compound, while MACCS groups by chemical element. An appropriate interfacing methodbetween MAAP and MACCS has therefore long been requested by users. This study suggests a way ofextracting relevant information from MAAP results and providing proper source term information toMACCS by an appropriate treatment. Various parameters are covered in terms of magnitude and mannerof release in this study, and special treatment is made for a bypass scenario. It is expected that thesuggested approach will provide an important contribution as a guide to interface MAAP and MACCSwhen performing radiological consequence analyses.
