Abstract

This study about burn up calculations on the HCLWR reactor with two dimensional hexagonal geometric models of uranium using SRAC COREBN has been carried. This study used uranium-235 and uranium-238 as the fuels, light water as coolant and moderator. The calculation was done with computational simulation of COREBN. The calculation aims to produce a conversion ratio more than 1 and a critical multiplication factor (keff). The research used fuels enrichment, burn up period, burn up step, linier power and volume fraction parameters. The percentage of enrichment from U1 and U3 were 3% and U2 was 2,5%. The volume fraction of each material was 52% fuels, 12% cladding, and 36% coolant, the reactor operating period for 548 days with 6 step of burn up then the reactorpower is 2400 MW and the linear poweris 1,792722 MW/cm. The calculation of conversion ratio was 1,01233 and keff was 0,901.
