Intermediate Energy Nuclear Reaction Code Intercomparison: Applications to Transmutation of Long-Lived Reactor Wastes

Results are summarized of an international code comparison designed to test codes that may provide the necessary nuclear data to evaluate schemes for the accelerator-driven transmutation of long-lived reactor wastes. This comparison of intermediate energy nuclear reaction codes was organized by the Organization for Economic Cooperation and Development Nuclear Energy Agency (NEA) Nuclear Science Committee and presents results for thin-target double-differential (p,xn) and (p,xp) cross sections of ⁹⁰Zr and ²⁰⁸Pb targets at incident energies of 25 to 1600 MeV. Here, results are presented primarily for ⁹⁰Zr targets, and indications are given of the degree of dependability of these codes for thin-target measurements by use of a few comparisons of calculated and experimental yields. Broader comparisons are presented in the final NEA report.
