Gas cooled fast reactor-GFR is one of six types of generation IV reactors. The long terms goals of the Generation IV reactor is to develop a safe, proliferation-resistant nuclear system. Minimizing on enrichment of U-235 is one way to avoid the proliferation issue. Now, we even use directly natural uranium as the fuel in reactor core with applying Modified CANDLE burn up scheme. In this study variations of fuel region movement with modified CANDLE burn up scheme in radial direction of GFR was conducted. There are three variation of fuel region movement scheme that used in this study. The power range 300-550 MWTh. The neutronics calculation was performed by SRAC (PIJ-Citation) module. The result of calculation show that one of the movement scheme provides a critically value with 0,3% excess reactivity for begining of life (BOL) conditions.
