ABSTRACT CALCULATION ANALYSIS OF WIMS/D4-BATAN-2DIFF NEUTRON SPECTRUM ON RSGGAS WITH CADMIUM RATIO. The calculation analysis of WIMS/D4- Batan-2DIFF neutron spectrum was perfonned by comparison the calculation result of cadmium ratio with the experiment result on CIP, 1P2, IP3 and IP4 irradiation positions of RSG GAS tenth core. The foils of Au, Mn and Co \\"ere used for detennination of the measured and calculated cadmium ratios. Spectrum calculation was done in 69 energy group \\ith 541 energy group (till 10 MeV) cross section of foil absolption reaction. The difference values benveen cadmium ratio calculation and ex-periment result for all cases were in intef\'al of 11,0% -26,3% \\"hich are out of measurement deviation range. From these results, it concluded that the use of WIM/D4 in generating group constant is not sufficient to obtain the neutron spectrum, especially for non-fuel region.
