Abstract

The purpose of this research is to study of replacing the type of cylinder fuel in the TRIGA 2000 reactor into the type of plate.We modeled the core of the TRIGA 2000 reactor geometry equiped with a moderator,a graphite reflector, AgInCd as control rods, and a reactor tank without changing the dimension of the reactor core.The composition of the fuel was U 3 Si 2 Al with a 19.75% enrichment and 2.96 gU/π‘π‘š 3 density.Criticality study was carried out on a 5x5 core configuration, consist of 16 fuel assemblies and 4 control fuel assemblies.Simulation has been done using the MCNPX.It has been found that the π‘˜ 𝑒𝑓𝑓 value when all of the neutron absorbers withdrawn was 1.07100Β± 0.00017.
