Gas Cooled Fast Reactor-GFR is one of the Generation IV reactors, a high temperature helium-cooled with a closed fuel cycle. Due to target operation on 2022-2030, this reactor type still need for further research and development technologies. In this paper, we investigated neutronics performances of GFR balance type core with modified CANDLE burn up scheme in radial direction. The power range of 300-700 MWTh. Modified CANDLE burn up scheme was chosen so that the reactor could operate with natural uranium input only. The neutronics calculation were performed using SRAC 2002 with JENDL 4.0 nuclear data library. The results show reactor could operate critically for 10 years without refueling with burn up level 20% HM
