Abstract: Safety measures play an important role in ensuring any system, although nuclear systems always require more safeguards than necessary. From this principle comes the importance of this research, which aims to conduct a study of neutron simulations and modelling to ensure safe installation of PGAA devices in the NB1 channel from the TRIGA Research Reactor at the Maamoura Center for Nuclear Studies. During this study, we used the Monte Carlo method using the MCNP6/X code. This study aims to determine the neutron profile, neutron distribution, and secondary gamma rays produced during the passage of the neutron flux in the collimator channel, sapphire and the vacuum channel that is maintained for the immediate neutron activation analysis (PGAA).

Keywords: collimator; neutron flux; PGAA; Monte Carlo; MCNP.
