Description
A study of passive safety test using JOYO has been carried out to demonstrate the inherent safety of sodium cooled fast reactors. In this study, emphasis was placed on the improvement of the accuracy of plant dynamics calculations. The Mimir-N2 analysis code, developed to analyze JOYO plant dynamics, was selected as the standard code for predicting plant behavior during transients. Mimir-N2 was upgraded to be modified based on the plant data of plant characteristics, natural circulation tests during JOYO MK-II and the manual scram tests and loss of power test, etc. during MK-III performance tests. This year, the analysis of the UTOP and the ULOF tests by the Mimir-N2, which are planned for the passive safety tests, and evaluations of the plant structure response were carried out. As a result, we could plan the future UTOP and the ULOF tests conditions. (author)
