Blanket replacement in toroidal fusion reactors

A conceptual design for a tokamak fusion reactor is described, in which the maintenance of the blanket structure is achieved by sub-assembly replacement, thus minimizing reactor shut-down time. All major components are moved linearly so that dismantling and re-assembly can be more easily effected by remotely controlled machines. Illustrated descriptions embodying these concepts are given of tokamak reactors with and without a divertor and a Reversed Field Pinch Reactor. Consideration of some advantages and problems in realizing these designs amply justifies their further development
