5. Operation and maintenance in a nuclear environment

The injectors will be operating in a very hostile nuclear environment, and that will have an impact on many aspects of the NBI system, for example, the activation and transmutation of materials, the requirement to maintain confinement barriers under operational response and accidental scenarios, etc., and the necessity to meet all nuclear safety requirements. A particularly important aspect of operating in a nuclear environment is that all the components in the actual injectors and the injector vessel and the nuclear shielding around the injectors will become activated during operation; that no human intervention for maintenance operations will be

possible, so all maintenance must be carried out remotely; and that requirement must be considered at all stages of the design of the injection system.
