SPECTRA-IV, benchmark spectra based on LIB-IV

R.B. Kidman

Abstract

Flux and adjoint spectra for each of the Cross Section Evaluation Working Group fast reactor benchmarks are numerically and graphically presented in this handbook. The spectra were computed using a 50-group cross-section library (LIB-IV) that was generated with the MINX processing code using ENDF/B-IV data. The graphical figures compare smooth interpolated curves for the central flux, edge flux, central adjoint, transport reaction rate, and original cross-section averaging weighting function.
