CERES is plant system analysis code for LMRs developed by CRIEPI. CERES has a function of calculating multidimensional flow in the plena of a coolant in addition to that in one-dimensional plant network calculation. To verify the CERES code, analyses were performed by using the result of the plant trip test from the partial power operation of the prototype FBR "MONJU" that had been executed in December, 1995. The verification work was performed as a joint research of CRIEPI and JAEA. The analysis intended for primary/secondary/auxiliary cooling system and the analysis that was focused on three dimension plenum thermal-hydraulic characteristics were executed. Analytical results by the CERES code showed good agreement with the results of the test of the "MONJU". Fundamental abilities of the CERES as a plant dynamics calculation code had been verified through these analyses.
