Benchmark Validation of the Fendl-1 Nuclear Data Library - A Co-Ordinated International Effort

A co-ordinated international benchmark validation 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 of this task was to qualify the FENDL-1 working libraries for fusion applications and to elaborate recommendations for further data improvements. A large variety of existing integral 14 MeV benchmark experiments has been analysed with the FENDL-1 working libraries for continuous energy Monte Carlo and multigroup discrete ordinates calculations. This paper reviews the FENDL-1 benchmark analyses and gives an overview on the major findings, conclusions and recommendations for further data improvements to be included in the forthcoming FENDL-2 data library.
