By adding actinide minor elements to the fuel, it can be seen how the performance of the fuel cell during its burn-up can be seen. Parameter studies in this study were obtained from the calculation of the level of uranium nitrite fuel cells at a ratio of 95% uranium nitrite and 5% the addition of minor actinides with Am241 and Np237 nuclides with a composition of 1% to 7% with S-CO2 coolant. The percentage of cell level volume fraction is 65% fuel, 10% cladding (stainless steel) and 25% coolant. Calculation results for the fuel cell level survey parameters are obtained from the K-inf value over the 120 year burn-up history, the burn-up level over the 120 year burn-up history, the atomic density associated with U235, U238 and Pu239, the conversion ratio over the 120 year burn-up history . The results of the calculation of the cell-level neutronic parameters show the impact of the minor addition of actinide to uranium nitrite fuel on the performance of the fuel cell during its burn-up. Keywords: fuel cell, uranium nitrite, actinide minor, S-CO2 ","PeriodicalId":210626,"journal":{"name":"Jurnal Penelitian Sains","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132003717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
