Validation of the CSAS25 module of SCALE: Part 2, Highly enriched uranium metal systems
This is Part 2 of a series of validation studies dealing with highly enriched uranium systems. For this study six sets of critical experiments involving uranium metal have been modeled and an effective multiplication factor, k{sub eff}, calculated for each experiment. 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 Va. 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 Va 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 END/B-IV, and the 123 group Gam-Thermos. Provided 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.
