The TBR Error Bar - Which Cross-Sections Actually Matter
Abstract
The credible nuclear-data uncertainty on the TBR is set by the light breeding channels — ⁶Li(n,t), ⁷Li(n,n't), ⁹Be(n,2n) show a 55–66% TALYS-vs-ENDF model spread at 14 MeV, against ~15% for heavy structural channels. The load-bearing light channels must come from evaluated covariances, not model defaults.
