Feasibility study of photo-neutron flux in various irradiation channels of Ghana MNSR using a Monte Carlo code

► The photo-neutron source was investigated within Ghana MNSR irradiation channels. ► Irradiation channels under study were inner, outer and the fission chamber. ► Thermal rated power at sub-critical state was estimated. ► Neutron flux variation was investigated within the channels. ► MCNP code has been used to investigate the flux variation.
