WebAug 5, 2015 · Traditionally, safety regulation for NPPs design and operation has been based on Deterministic Safety Assessment (DSA) methods to verify criteria that assure plant safety in a number of postulated Design Basis Accident (DBA) scenarios. Referring to such criteria, it is also possible to identify those plant Structures, Systems, and … WebOct 1, 2024 · Notably, the safety analysis of DBA has been performed with Probabilistic Safety Assessment (PSA) and Deterministic Safety Assessment (DSA) independently focusing on a thermal–hydraulic phenomena analysis and safety verification. However, the assessment of DEC requires the organic integration of the two methods (KINS, 2012).
