The Divertor Exhaust of a Compact Spherical-Tokamak Breeder: A Stacked-Detachment Portfolio, and a Requirement Not Yet a Closed Number

A portfolio assessment of divertor and heat-exhaust options for the compact breeder, spanning conventional, advanced-magnetic, and liquid-metal targets, ranked against the concentrated exhaust power of a compact machine. The flowing-lithium vapor-box option is developed in a dedicated companion. Screening bounds, honest gates carried; physics and engineering only.

Abstract

A portfolio assessment of divertor and heat-exhaust options for the compact breeder, spanning conventional, advanced-magnetic, and liquid-metal targets, ranked against the concentrated exhaust power of a compact machine. The flowing-lithium vapor-box option is developed in a dedicated companion. Screening bounds, honest gates carried; physics and engineering only.
