Description
This paper reports on an experiment carried out to study the behavior of 14-MeV neutrons incident to a large cavity composed of mortar coated with stainless steel, which simulates a neutral beam injector (NBI) in a tokamak fusion reactor. Fast neutron spectra and reaction rate distributions were measured inside the cavity with a 5.06-cm-high x 5.06-cm-diam NE-213 spectrometer as well as 232Th and 235U fission counters. The experimental results were analyzed with a Monte Carlo MCNP-3 code, using nuclear data files from the JENDL series and from ENDF/B-IV. Calculations with two discrete ordinates codes, DOT3.5 and BERMUDA-2DN, using ENDF/B-IV and JENDL nuclear data files, were also compared with the measurements to study their applicability for NBI design
