[en] The present research concerns about developing a computational algorithm for the analysis of post boiling fuel temperature, based on the sodium boiling model proposed by USNRC. The model selection comes from the fact that the analysis of LMR sodium boiling had already been done using this model being coupled with SSC-L, and therefore its theory is believed to be a quite adequate option for compatibility to SSC-K. Physical phenomena characterizing UTO, ULOF, and ULOHS for KALIMER are analyzed for evaluation of the developed algorithm. The results obtained from the calculation are also compared with those of a previous model to confirm physical consistencies
