Fusion Neutronics Benchmark Experiment on Structural and Advanced Blanket Materials - Leakage Gamma-ray Spectrum Measurement -

Abstract

Benchmark experiments have been carried out to validate the nuclear data files of JENDL-3.2, JENDL fusion file, ENDF/B-VI, FENDLIE-l.0 and FENDLIE-2.0 for blanket materials of LiAl0 2 , Liz TI0 3 and LizZr03 and structural materials, i.e., C, V, Fe, SS-316, Cu, Pb and W. Some discrepancies between measured and calculated spectra were observed. However, the CIE values for the energy multiplied integral spectrum show that all of the nuclear data files were fairly reliable.
