Perhitungan Burn Up Model Assembly Heksagonal pada Reaktor SCWR Menggunakan Bahan Bakarr Thorium

The research about the calculation of burn-up model hexagonal assembly in SCWR reactor using thorium as fuel materials has been done. This uses thorium-232 and uranium-233 materials. Calculations were performed ASMBURN code SRAC program, by determining enrichment, cell radius, analyzing atomic density after burn up, increasing up level, change linear heat. results obtained show value efficient enrichment at 4% with 0.3902 cm 0.4508 cladding, 0.5586 moderator. Th232 decreased for each period meanwhile, U233, U235, Pu239 increased. keff will decrease along addition greater
