Source term atmospheric release and core inventory analysis for the PUSPATI TRIGA reactor under severe accident conditions

The estimation of core inventory and source term of nuclear reactor is a part of procedures for conducting a Level 2 Probabilistic Safety Assessment (PSA). Currently, there are not many studies in this area for nuclear research reactors, as it is yet to be made compulsory in the regulatory licensing...
