The examination of the FNSF maintenance approach

This paper addresses an approach to maintain and sustain the high-intensity Fusion Nuclear Science Facility (FNSF) experimental fusion facility that would enable it to have extended operations exceeding several exchanges of the primary power core components. The maintenance approach must be safe, quick, reliable, repeatable and precise. Moreover, this approach and equipment should be able to be extrapolated to the future fusion demonstration power plant (DEMO). A preliminary evaluation is presented for the underlying maintenance and safety requirements and the key design approaches that will define the FNSF and shape future high-power fusion facilities.
