Uncertainties in nuclear data have led to the promotion of benchmark experiments by the European Technology programme. The aim of this experiment was to obtain accurate experimental data for improving the nuclear database and methods used in the shielding designs, through a rigorous analysis of the results. A large SS-316 block was irradiated by 14-MeV neutrons. The neutron fluxes and spectra at different depths, up to 65 cm inside the block, were measured by means of fission chambers and activation foils, characterised by different energy response ranges. Gamma-ray dose measurements were performed with ionisation chambers and thermoluminescent dosemeters. The first results are presented, as well as the comparison with calculations by the S(n) code BISTRO and the Monte Carlo code MCNP, using the European JEF/EFF libraries.
