Abstract EN
Fast quasi-monoenergetic neutrons can be produced by accelerating charged deuterons on tritium solid targets.
Benchmark experiments were performed in many laboratories with intense D-T neutron sources.
The aim is to validate the computational models and nuclear data for fusion applications.
The detailed information on the neutron source term is highly important for the benchmark analyses.
At present, the MCNP family of codes cannot explicitly model the D-T reaction for Deuterons in the KeV energy range.
The physics for the D-T neutron production was modelled at ENEA (Italy) in the SOURCE and SRCDX subroutines to compile with the MCNP source code.
Some improvements to the original subroutines were introduced.
The differential cross-sections for the D-T reaction from the ENDF/B-VII library were built into the code.
The relativistic approach was implemented for neutron kinematics.
The new D-T neutron source model was applied to the MCNP5 simulation of the tungsten integral experiment performed at the OKTAVIAN facility.
The uncertainty associated with the realistic D-T reactions was separated from the total uncertainty of the source term.
The outcome of the benchmark analysis was an improvement in the quality of the computational model of the experiment.
