The present paper describes the new, original implementation of a point-wise neutron treatment that is made available with FLUKA v4.3-0 (https://fluka.cern). The development is based on the pre-processed neutron data libraries for Geant4 code (https://cern.ch/geant4). The implementation was written from scratch in C++ and is able to load information from all available databases (ENDF, JEFF, JENDL, CENDL, BROND), including the materials with S(α,β,T) nuclear binding effects. It can perform online Doppler broadening at any temperature defined by the user. It carries out all interactions in a fully correlated way, conserving quantities like energy and momentum with the exception of S(α,β,T). Special attention has been given to minimize the CPU penalty, which is typically associated with neutron point-wise interactions.
