For fusion reactor nuclear analyses we produce new nuclear group constant sets, we have produced new nuclear group constant sets similar with FUSION-J3 from JENDL-4.0 and FENDL-3.0. The materials in these sets are $$^{1}$$H, $$^{2}$$H, $$^{3}$$He, $$^{4}$$He, $$^{6}$$Li, $$^{7}$$Li, $$^{9}$$Be, $$^{10}$$B, $$^{11}$$B, $$^{12}$$C, $$^{14}$$N, $$^{16}$$O, $$^{19}$$F, $$^{23}$$Na, Mg, $$^{27}$$Al, Si, $$^{31}$$P, S, K, Ca, Ti, $$^{51}$$V, Cr, $$^{55}$$Mn, Fe, Co, Ni, Cu, Zr, $$^{93}$$Nb, Mo, Cd, W, Pb, $$^{209}$$Bi, Cl, $$^{181}$$Ta, Sn and Ga. The nuclear group constant sets of JENDL-4.0 and FENDL-3.0, FUSION-J40 and FUISON-F30 (neutron: 175 groups, $$gamma$$: 42 groups, P5 approximation), were produced from MATXS files of JENDL-4.0 and FENDL-3.0, which were newly processed with the NJOY99 code, with the TRANSX code. KERMA, DPA and gas production libraries were also prepared from the MATXS files with TRANSX. Several test calculations are carried out in order to validate these nuclear group constant sets. They suggest that these group constant sets have no problem.
