> Engineering work halted 30+ years ago. There has been no recent work on structural materials that could withstand the neutron bombardment

We've made massive strides compacting designs, thereby transforming their unit-economic envelope, using low-temperature superconducting magnets. Those magnets continue to improve, driving potential gains in designs faster than experiments can be funded and built. Optimizing for structural materials, or even blanket versus replaceable structure, seems premature when we don't know the parameters or even type of bombardment we'd be working with.

Bombardment is with hot neutrons.

Period.
