Axial and radial distribution of thermal and epithermal neutron fluxes in irradiation channels of the Ghana research reactor-1 using foil activation analysis. Annals of Nuclear Energy, 37(8), 1027-1035http://197.255.68.203/handle/123456789/4157The experimental method (foil activation) was used to determine the neutron fluxes in two outer irradiation channels of the Ghana Research Reactor-1. In the experimental procedure, it was observed that the fluxes rise to a peak before falling and then finally leveling out, axially. Axially and radially, it was also observed that the fluxes in the center of the channels were lower than those on the sides. Radially, the fluxes dipped in the center while they increased monotonically towards the sides of the channels. The results have shown that there are flux variations within the irradiation channels at both axial and radial directions.enFoil activation, Cadmium FilterArticle
