Design of tokamak reactors for maintainability

With the advent of deuterium-tritium burning capability, the design of future tokamak reactors will be impacted by the requirement for remote maintenance. The maintenance philosophy must be defined early in the engineering phase of a new program, and suitable management techniques adopted to insure consistent implementation of the maintenance criteria in the detail design. General categories of maintenance tasks should be determined for each major system in the reactor. Detailed maintenance procedures should be developed for each system, and special tooling requirements should be identified. The various maintenance tasks and tooling should be proof-tested prior to their first operational use
