  1. LANL Covariances in ENDF/B-VII.1b2 • Actinides • 233U: MF33,MT1,2,4,16,17,18,37,102 + MF31,MT455,456 • 235U: MF33,MT1,2,4,16,17,18,102 + MF31,MT452,456 • 238U: MF33,MT1,2,4,16,17,18,102 + MF31,MT452,456 • 238Pu: MF33,MT1,2,4,16,17,18,102 + MF31,MT452,456 + MF35,MT18 • 239Pu: MF33,MT1,2,4,16,18,37,102 + MF31,MT452,456 + MF35,MT18 • 240Pu: MF33,MT1,2,4,16,17,18,102 + MF31,MT456 + MF35,MT18 • 241Pu: MF33,MT18 • 241Am: MF33,MT1,2,4,16,17,18,37,102+MF31,MT452,455,456+MF32,MT151 • To be done before VII.1 release • 241Pu: slight revision of fission cross section covariance

  2. Light Nuclei • R-Matrix • 1H: covariances not in file! • 4He: MF33, MT1,2 • 6Li: MF33, MT105 • 10B: MF33, MT107,800,801 • 16O: MF33, MT2,800 + MF34,MT2 • Low-Fidelity (NOT IN ENDF/B-VII.1b2 !) • 2H: MF33, MT1,2,(16),102 • 3H: MF33, MT1,(2),16 • 3He: MF33, MT1,(2),102,103,104 • 4He: MF33, MT1,(2) • 7Li: MF33, MT1,2,4,16,24,25,51-82,102,104,851-859 (Young’s evaluation) • 7Be: MF33, MT(1),2,600,650,800

  3. Light Nuclei (cont’d) • Low-Fidelity (cont’d) (NOT IN ENDF/B-VII.1b2 !) • 9Be: MF33, MT1,(2),16,102,103,104,105,107,600,650,(700),701,800 • 11B: MF33, MT1,(2),4,16,22,28,102,103,105,107 • 0C: MF33, MT1,2,(4),5,28,102,103,104,107 (LA150) • 14N: MF33, MT1,2,(4),5,16,102,(103),(104),(105),107,108,600-606, 650-653, 700, 701, 800-810 (LA150) • 15N: MF33, MT1,(2),4,16,22,28,102,103,104,105,107 • 17O: MF33, MT(1),2,4,16,22,28,102,103,104,107 • 19F: MF33, MT1,(2),4,16,22,28 • To be done before VII.1 release • Include 1H covariances in file • Include low-fidelity?
