First-Wall Damage Lifetime - How Long the Wall Survives
Abstract
The survival question, computed on an independent code stack: displacement damage (~9.78 dpa/fpy behind armor), helium/hydrogen bubble swelling (accumulating but not life-limiting), plasma-material sputtering/erosion, and hydrogenic permeation. The governing life-limiter is displacement-driven embrittlement, and the wall is a scheduled-replacement component on a defined damage budget.
