Abstract
In the present study, the fast spectrum transmutation experimental facility (FASTEF) core that considered for the MYRRHA reactor is modelled using Monte Carlo MCNPX code. The effect of changing the type of material and radius of the cylindrical target source as well as the energy of the proton beam on the final production of neutrons and the subcritical multiplication of the system are evaluated. Subcritical models of the investigated reactor have been numerically investigated as well. six target materials; uranium (U), lead-bismuth eutectic (LBE), tungsten (W), lead (Pb), bismuth (Bi), and copper (Cu) are used with varying target radii from 3.5 to 20 cm. The beam energy is varied from 0.2 to 2.0GeV. The present study depends on numerical calculations of the subcritical multiplication factors and the efficiency of the external source using MCNPX code. The obtained results revealed that the favourable target material, radius, and beam energy can be precisely determined.
