A temporary file of JENDL-3 named as JENDL-3T was examined through the analysis of fusion blanket benchmark experiments at FNS of JAERI. The experiments were carried out on the cylindrical assemblies of lithium-oxide, graphite, lithium-oxide following a graphite reflector and beryllium-sandwich lithium-oxide. Measured quantities were tritium production rates, fission rates, reaction rates of foils and so on. The transport code DOT3.5 was used for the analysis. It becomes clear from this integral test that the most of calculated reaction rates agree well with the measured ones within 10 %. In the case of Be-sandwiched assembly, however, large deviations are observed between measured and calculated results near the Be-region. Reevaluation is recommended for the nuclear data of Be in JENDL-3T.
