ENDF/B-VIII.1 · SCALE 56 groups · NJOY and AMPX routes · release v1.2
Every covariance matrix of the two processed libraries (release v1.2) for 467 nuclides: the NJOY route (4894 matrices; its files are the ones that load in JANIS) and SCALE's own AMPX route (5260). 266 nuclides are processed from ENDF/B-VIII.1, 9 from older ENDF/B releases and 192 from the BLO low-fidelity covariances (2008, not CSEWG-approved) on ENDF/B-VIII.1 cross sections, the last two groups made the way SCALE made its own entries; the source of every nuclide is listed separately. Choose a nuclide and a pair of reactions, and switch between the libraries or compare them.
Most of this work, including this page, was generated with AI (Claude, Anthropic) under the direction of Ian H; it has not been independently reviewed. The method and the comparison with the AMPX route are in the paper; to open the files in JANIS itself, see the JANIS guide.
