“…The customized checks included a detailed photon production assessment ,6 the infinite medium comparisons described in this report, and experimental benchmarks including criticality: iron benchmark^,^ and Livermore Pulsed Spheres. 8 We report here a series of infinite media calculations that were undertaken for each nuclide in the ENDFGO library. Each nuclide was compared to the corresponding ENDF/B-V nuclide and/or the MCNP Recommended Data Set, and the differences were fully explored.…”
