Abstract

A consumable, scheduled-replacement architecture for the inboard centrepost of a compact spherical-tokamak breeder. Four coupled analyses on the frozen design point: a 3-D OpenMC coverage-versus-protection neutronics scan, a coil structural finite-element check against the analytic Lame stress, a fused strain-rate-plus-magnetization quench detector, and a maintenance-cadence/availability (RAMI) model. The centrepost's finite life becomes a scheduled maintenance line item rather than a barrier. Physics and engineering only; honest gates carried.
