Abstract

Research on the analysis of recycling, plutonium, and minor actinides in the Gas Cooled Fast Reactor (GFCR) using SRAC COREBN has been done. This research uses a fuel mixture of uranium, plutonium, and minor actinides. The analysis was conducted with computational simulation using the COREBN code, an additional code to SRAC. The purpose of this research is to find out the influence of the addition of plutonium and actinide on the composition of nuclear fuel at the end of reactor operation and the limitation of the value of the multiplication factor (keff at the end of the reactor burn up period). Found in this research is the final value, the multiplication factor (keff) of 1.19964, and the conversion ratio value of 0.766813 in the burn-up period of 1515 days as well as the maximum power density value of 125.85 watts/cm³, the relative power density value at the radius y of 1,230263 and radius x equal to 1.19737 the atomic density value experienced a change in the number of nuclides in the types of nuclides U235, U238, Pu239, Pu241, Np237, and Am243 at the end of the burn-up period.

Abstract

It has been done a variation of CaCO 3, which is 0.95; 1.00; 1.05; and 1,10, through phase formation of BSCCO-2212 superconductor using a wet-mixing method. Samples were dissolved with HNO 3 and distilled by water slowly until the color was clean blue, then gradually dried out at temperatures of 300, 400, and 600 °C. The samples were calcined for 10 hours at 800°C and sintered at 820°C for 20 hours. The XRD's characterization results show that the highest volume fraction was 76.65% in the Ca 1.05 sample. The lowest volume fraction was 49.85% in the Ca 1.10 sample. Meanwhile, the highest degree of orientation was 44.27% in the Ca 1.00 sample, and the lowest degree of orientation was 8.58% in the Ca 1.10 sample. SEM's characterization shows that all samples have been oriented and relatively little space between slabs (voids).
