Replacement parts! That may sound flippant but yeah, replace the components/structural members subject to neutron flux before they get too compromised, basically. This is yet another reason that fusion research is expensive and time consuming, the cost involved in manufacturing these components and time lost in painstaking teardowns and overhauls between test runs.
