FENDL-3 benchmark test with neutronics experiments related to fusion in Japan

The Importance of Resonance Self-Shielding Part 2

“…Here using the TART Monte Carlo code we demonstrated the importance of neutron resonance selfshielding to calculate a neutron source problem, recently described as difficult to obtain consistent answers between Monte Carlo and deterministic codes [2]. First, we presented results for exactly the same system with and without self-shielding, in order to demonstrate the magnitude of the effect.…”

“…Here in Part 2 we describe resonance self-shielding in source problem calculations. We have selected a problem described at a recent meeting on data for fusion neutrons applications as a difficult case to obtain agreement between Monte Carlo and deterministic calculations [2]. Below 20 MeV the FENDL-3.1d library is similar to ENDF/B-VIII.0, so we focus on the latter for convenience.…”

Simultaneous measurements for fast neutron flux and tritium production rate using pulse shape discrimination and single crystal CVD diamond detector

“…Our model included the various components of the experiment, such as the neutron source, moderator, the SDD, and the irradiation room. We ensured that the angular distributions of neutron energy and flux at the target matched those previously validated at the Fusion Neutron Source (FNS) of the Japan Atomic Energy Agency [37][38][39][40], because the OKTAVIAN employed the same target system as that in FNS. Subsequently, we compared the neutron energy spectrum at the position of the SDD to the deduced neutron energy spectrum.…”
