Description

In the ENDF/B-VIII.1 beta3 La139, it was noted that the cross reaction covariances were mathematically impossible. FUDGE did not check these values. FUDGE should implement these checks too.

Research direction

No files or tests are named. Start by locating FUDGE's existing validation for reaction and material cross covariances, then use the ENDF/B-VIII.1 beta3 La139 case as the reference example. Done means mathematically impossible cross-covariance values are detected by checks rather than accepted silently.
