Impact of uncertainties in /sup 238/U resonance parameters on performance parameters of thermal lattices

The calculated and measured values of integral parameters may be considered discrepant if their differences are significantly greater than the combined uncertainties assigned to the integral experiment, the calculational methods, and the evaluated differential data. This paper presents an assessment of the uncertainties in the calculated values of performance parameters of selected uranium metal and uranium oxide lattices due to uncertainties in ENDF/B-V data, particularly the /sup 238/U resolved resonance parameters
