A program is underway at Los Alamos National Laboratory to develop nuclear data libraries for incident neutrons and protons to 150 MeV for accelerator-driven applications. These libraries will be used initially for design of an accelerator-based facility to produce tritium, including analysis of system performance, induced radiation doses, material activation, heating, damage, and shielding requirements. The libraries are based primarily on nuclear model calculations with the GNASH reaction theory code, including thorough benchmark of the model calculations against experimental data. All evaluations include specification of production cross sections for light particles, gamma rays, and heavy recoil particles, energy-angle correlated spectra for secondary light particles, and energy spectra for gamma rays and heavy recoil nuclei. The neutron evaluations are combined with ENDF/B-VI evaluations below 20 MeV. To date, neutron and proton evaluations have been completed or 2H, 12C, 16O, 27Al, 28,29,30Si, 40Ca, 54,56,57,58Fe, 182,183,184,186W, and 206,207,208Pb.
