Abstract

Nuclear-safety-related and shielding analyses were performed for the quasi-optical design of the electron-cyclotron-heating launcher installed in the ITER upper port. The critical nuclear responses, affecting the nuclear safety and technical performance of the launcher and nearby components, were calculated using the MCNP5 3-D radiation transport code. The computer-aided design (CAD) interface program McCad was applied for the conversion of the CAD model into MCNP geometry description. The radiation effects of the launcher´s halved internal shield were estimated on the chemical-vapor-deposit diamond windows, vacuum vessel, and toroidal field coils. It was revealed that the nuclear-safety requirements were satisfied.
