Severe Accident (SA) integral codes, such as MELCOR, are widely employed to analyze accidental scenarios and evaluate source term. To ensure consistency and reliability, physical models within codes must be validated against experimental data. Therefore, this paper describes the MELCOR 2.2 modelling of two small-scale Fission Product Release (FPR) experiments. A generic approach has been developed to simulate the VEGA [1] and HEVA [2] programs. Two MELCOR’s release models, namely Revised CORSOR-Booth (RCB), the default in MELCOR, and ORNL-Booth (OB), the latest version proposed by developers [3], are employed. The focus is put on Cesium (Cs) releases, as MELCOR evaluates the release of any radionuclides relative to Cs.

Abstract
Severe Accident (SA) integral codes, such as MELCOR, are widely employed to analyze accidental scenarios and evaluate source term. To ensure consistency and reliability, physical models within codes must be validated against experimental data. Therefore, this paper describes the MELCOR 2.2 modelling of two small-scale Fission Product Release (FPR) experiments. A generic approach has been developed to simulate the VEGA [1] and HEVA [2] programs. Two MELCOR’s release models, namely Revised CORSOR-Booth (RCB), the default in MELCOR, and ORNL-Booth (OB), the latest version proposed by developers [3], are employed. The focus is put on Cesium (Cs) releases, as MELCOR evaluates the release of any radionuclides relative to Cs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
