Abstract

Nuclear safety related analyses were performed for the Quasi-Optical (QO) design of the Electron Cyclotron Heating (ECH) launcher installed in the ITER upper port. The critical nuclear responses, effecting nuclear safety of the launcher and nearby components, were calculated using the MCNP5 3D radiation transport code. The CAD interface programme 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 (CVD) diamond windows, vacuum vessel, and Toroidal Field Coils (TFC). It was revealed that the nuclear safety requirements were satisfied.
