Abstract

ABSTRACT. FLEXBLUE reactor is France’s small modular power reactor type of pressurized water reactor with 160 MWe. This reactor is based on ocean site which is suitable to be built in archipelagoes like Indonesia. The purpose of the present work is to evaluate radioactivity inventory in FLEXBLUE reactor core. The analysis was carried out by calculations using the ORIGEN-2 program. Calculations were carried out based on pin cell calculations, where in the pin cell there were 4 regions namely UO2 fuel region with enrichment of 4.95%, region 2 vacuum area containing He, region 3 in the form of cladding Zr-4 and Region 4 are extra regions consisting of homogenization of Gd2O3 and H2O. The results obtained were radionuclide inventory in a reactor consisting of 8 radionuclide groups namely Tritium, Noble gas, Halogen, Alkali metal, Tellurium, Strontium and Barium, Nobel metal, Lanthanide and Cerium. The biggest radionuclide activity was in the Halogen group namely nuclei I-134 of 1.12E+18 Bq. In addition, it also obtained activity from large and dangerous gamma transmitter nuclides for the body, namely I-131 and Cs-137, each of which had activities of 4.92E+17 Bq and 2.72E+16 Bq.
