35. Results of some analyses using JENDL/HE were also introduced as those of benchmark calculations. The calculations using JENDL/HE show good performance. Reviewed were status of method and tools of the evaluation for JENDL High Energy File (JENDL/HE-2007). Especially, improvements of cluster-particle emission spectra and production cross sections. Summary JAPAN ATOMIC ENERGY AGENCY The first version of JENDL/HE (JENDL/HE-2004 ) has been released in March, 2004 with neutron and proton nuclear data of 66 nuclides up to 3 GeV. Soon, the second version of JENDL/HE (JENDL/HE-2007) will be released with those of totally over 100 nuclides including actinide ones. 35
