Abstract
Deuterium-Tritium (D-T) interactions produce almost monochromatic neutrons with about 14 MeV energy.
These neutrons are used in benchmark experiments as well as for neutron cross sections assessment in fusion reactors technology. 
The possibility to moderate 14 MeV neutrons for purposes beyond fusion is worth to be studied in relation to projects of intense D-T sources. 
In this preliminary study, carried out using the MCNP Monte Carlo code, the moderation of 14 MeV neutrons is approached foreseeing the use of combination of metallic materials as pre-moderator and reflectors coupled to standard water moderators.
