MELCOR validation study on sodium pool fire model with comparison to SPHINCS

Louie, D. L. Y.*; Aoyagi, Mitsuhiro

This paper describes progress of an international collaborative research in SFR sodium fire modeling between the United States and Japan under the framework of the Civil Nuclear Energy Research and Development Working Group (CNWG). In this collaboration between Sandia National Laboratories (SNL) and Japan Atomic Energy Agency (JAEA), the validation basis for and modeling capabilities of sodium pool fires in MELCOR of SNL and SPHINCS of JAEA are being assessed. Additional model improvements for the sodium pool fire in MELCOR are discussed. The MELCOR results for the sodium pool fire model enhancement in MELCOR agreed well with the JAEA's F7 pool fire experiments and compared closely with SPHINCS.
