【 摘 要 】

We describe recent evaluations of neutron and proton interaction cross sections up to 150 MeV in the LA150 Data Library, for use in MCNPX computer code simulations of accelerator-driven systems (ADS). An overview is provided of the nuclear theory used. A number of benchmark comparisons against experiments are described, for thin and thick-target neutron production, neutron transmission through macroscopic slabs, and neutron heating and damage. Future data needs for waste transmutation are also briefly described.
