Keywords:LORL Accident, CMMC Method, fission product, SFR, severe accident

A loss of reactor level accident (LORL) of a sodium cooled fast reactor (SFR) results in core degradation and causes fission products release from the reactor system to the environment. The authors couple Continuous Markov Chain and Monte Carlo(CMMC) method with AZORES code to investigate the fission product behavior during the LORL accident of the SFR.
