EVALUATION OF THE FISSION CROSS SECTION FOR U-233 AND COMPARISON WITH THAT FOR U-235Sumitomo Atomic Energy Industries, Ltd. 2-6-1 Kaji-cho, Chiyoda-ku, Tokyo 101 The fission cross section for U-233 was reevaluated in the energy range from 10 keV to 20 MeV, as a part of works for JENDL-3. This revise was performed on the basis of the recent experimental data published after 1982 in which JENDL-2 was released, and using the fission cross section of U-235 which was obtained by simultaneous evaluation for JENDL-3. Especially, the data of fission cross section ratio of U-233 to U-235 which were measured in Tohoku University in 1985 and 1987, were taken into account in the energy range from 200 keV to 7 MeV.
