摘要：

BUM-LIP calculation and comparison of the results were carried out to clarify the differences among the following latest evaluated nuclear data libraries: JENDL-3.2. ENDF/B-VI and JEF-2.2. The analyses showed that the differences seen among the current evaluated nuclear data libraries are small for evaluation of the amounts of many uranium and plutonium isotopes. However, several nuclides important for evaluation of nuclear fuel cycle as Pu-238, Cm-244, Sm-149 and Cs-134 showed large differences among used libraries. The chain analyses for the isotopes were conducted and the reasons for the differences were discussed. Based on the discussion. information of important cross section to obtain better agreement with the experimental results for Pu-238, Cm-244, Sm-149 and Cs-134 was shown.
