Particles Transportation and Nuclear Heating in a Tokamak by MCNPX and GEANT4

摘要

In this work as a first goal, GEANT4 Monte Carlo tool has been evaluated by means of comparison with MCNPX as alternate Monte Carlo tool in the field of tokamaks nuclear analysis. For this respect, the ITER-like geometry was studied as a candidate tokamak. The average neutron wall loading over the inner surface of the ITER first wall and neutron and gamma spectra in blanket have been calculated and compare to standards data. The results shows, GEANT4 under the HP model presents more agreement with MCNPX results. As the second achievement, the GEANT4 evaluation leads to make a confirmation to recent development in ITER nuclear heating enhancement.
