BENCHMARK TESTINGS OF EVALUATED DATA FILES ON FISSION REACTORS AND SHIELDING PROBLEMSJapan Atomic Energy Research Institute Tokai-mura, Naka-gun, Ibaraki-ken, 319-11 Japan Description of the JENDL-3 project, which is now going on in Japan aiming at standard domestic library of microscopic cross sections, are given stressing on the benchmark tests. Historical review of JENDL development is given first, and next scope of JENDL-3 and high-light of JENDL-3 evaluation are described. JENDL-3T, an adhoc file, is compiled for the testing of JENDL-3. Applicability of JENDL-3T nuclear data file to fission reactors (thermal and fast reactors) and shielding applications is checked through the wide range of the benchmark test performed by JNDC. From the results, overall predictability of JENDL-3T found to be satisfactory, however, some problems were also pointed out. By the reflection of these feedback information forth coming official version of JENDL-3 is expected to be greatly improved.
