JENDL high energy file 2004 and its benchmark tests

Full text: JENDL High Energy File (JENDL/HE) stores nuclear data for neutron and proton induced reactions up to 3 GeV. The 2004 version of JENDL/HE (JENDL/HE-2004) has been released in March, 2004. The JENDL/HE-2004 has data for total, elastic and isotope production cross sections, and double-differential cross section for secondary emitted neutron, proton, deuteron, triton, He-3 and alpha particles and pion for 66 nuclides. The data can be downloaded from the URL of http://wwwndc.tokai-sc.jaea.go.jp/. In the presentation, reported are the status of JENDL/HE, methods and tools for evaluation, samples of evaluated results and benchmark calculations as well as comparison with experimental data and those using LA150 and NRG2003 libraries. We have still discrepant evaluated data between the libraries to be solved. MCNPX calculations for TIARA integral experiment of iron and concrete using library processed from JENDL/HE-2004 can reproduce the experimental data reasonably. The MCNP library (ACE format) processed from JENDL/HE-2004 by using Japanese version of NJOY based on NJOY 99.97 is available upon the request. The update and addition of nuclides (planned full number of nuclides stored in JENDL/HE is 132) will be continuously done. (author)
