Validation of the CSAS25 module of SCALE. Part 3: Highly enriched uranium oxide systems
This is Part 3 of a series of validation studies dealing with highly enriched uranium systems. For this study only one set of critical experiments involving uranium dioxide have been modeled. The calculations of k[sub eff] were performed using the CSAS25 module of SCALE 4. The CSAS25 module is made up of three distinct programs, BONAMI-II, NITAWL-II, and KENO V.a. BONAMI-II and NITAWL-II are cross section manipulation routines capable of adjusting cross sections to take into account effects due to temperature, geometry, and composition. KENO V.a is a monte carlo program that determines k[sub eff] using the adjusted cross sections. Three cross section libraries available in SCALE were used for this study, the 16 group Hansen-Roach, the 27 group ENDF/B-IV, and the 123 group Gam-Thermos. Part 1 includes descriptions of the cross sections and the cross section manipulation routines. What follows in Section 2 are general descriptions of the experiments performed. Section 3, Results, consists primarily of tables listing the calculated k[sub eff]'s. Lastly, Sections 4 and 5 give a general discussion of observed trends in the results and suggested biases.
