Due to the sodium leak accident or troubles such as the furnace relay device falling, the operation of "Monju" has been suspended for approx. 20 years, and the system performance test has not also been executed at the rated power. However, the decay heat removal system (DHRS) has been operated at low flow rates in the primary and secondary sodium circuits, and its operating data are obtained. The performance of system or components can be evaluated using these data. The presentation addresses the overview of the study under the DHRS operation condition, and the following presentations report some of the results.
