Investigation of neutronic effects in structural material of a hybrid reactor by using the MCNPX Monte Carlo transport code
Description
In this study, 98 - 90 % Li2BeF4-2 - 10 % ThF4, 98 - 90 % Li2BeF4-2 - 10 % UF4, 98 - 90 % Li2BeF4-2 - 10 % UO2 and 100% Li2BeF4 molten salt-heavy metal was used as fluid. The fluids were used in the liquid first wall, liquid second wall and shield zones of the designed hybrid reactor system. A steel wall of 4 cm thickness is used as structural material. Proton, deuterium, tritium, He-3 and He-4 gas production rates are the parameters of radiation damage. In the study, the effect of liquid second wall thicknesses (20 cm, 30 cm, 40 cm, 50 cm) on the neutron flux distribution and the parameters of radiation damage according to neutron energy spectrum in the structural material were investigated for the selected fluids. A three-dimensional analysis was done by using the most recent version of the MCNPX-2.7.0 Monte Carlo code and the nuclear data library ENDF/B-VII. (orig.)
