Integral data tests of the FENDL-1 nuclear data library for fusion applications Summary report of the Internationl Working Group on ''Experimental and calculational benchmarks on fusion neutronics for FENDL validation''

A co-ordinated international benchmark task has been conducted to validate the fusion evaluated nuclear data library FENDL-1 through data tests against integral 14-MeV neutron experiments. The main objective was to qualify the FENDL-1 working libraries for fusion applications and to elaborate recommendations for further data improvements. Several laboratories and institutions from the European Union, Japan, the Russian Federation and the United States have contributed to the benchmark task. A large variety of existing integral 14 MeV benchmark experiments was analysed with the FENDL-1 working libraries covering the majority of fusion-relevant materials. The contributed benchmark experiments and analyses are presented and discussed in the report. A comprehensive documentation of the numerical data tests results is included in graphical and tabulated form. With regard to the data quality, it is summarised that fusion nuclear data have reached a high confidence level with the available FENDL-1 data library. With few exceptions this holds for the materials of highest importance for fusion reactor applications. Some still existing deficiencies and discrepancies have been identified and are recommended to be removed in the forthcoming FENDL-2 data file.
