Analysis of Radiation Damages of First Wall Materials for Fusion Reactor Using Monte Carlo Method

The purpose of ITER (International Thermonuclear Experimental Reactor) project is to verify technical and engineering problems for commercialization of fusion energy. Korea participates in this project and developing TBM (Test Blanket Module) Materials which must endure the high radiation filed and it is one of the crucial problems for the fusion technology. Several member states of ITER project are developing TBM for Tritium breeding part, DEMO. This is the core technology of fusion reactor. The first wall is the interface between TBM and fusion plasma. Many researches regarding to radiation resistance of first wall is ongoing now internationally, because resistance to high radiation exposure of first wall determine the operation period of fusion reactor. In this research radiation damage of TBM materials by high energy neutron and proton is evaluated by MCNPX and TRIM codes
