The Hansen-Roach 16-group cross-section library has been validated for use in pure uranium metal systems by modeling the Godiva critical assembly using the neutronics transport theory code ONEDANT to perform effective multiplication factor (k_eff) calculations. The cross-section library used contains data for 118 isotopes (34 unique elements), including the revised cross sections for 235U and ²³⁸U. The Godiva critical assembly is a 17.4-cm sphere composed of 93.7 wt% ²³⁵U, 1.0 wt% ²³⁴U, and 5.3 wt% ²³⁸U with an effective homogeneous density of 18.7 g/cm³.
