The ALEGRA radiation transport package implements diffusion, flux-limited diffusion, and SPn radiation transport for both gray and multigroup photon spectra. Comparisons of ALEGRA calculations with known solutions for a selection of benchmark problems for these transport theories are presented. ALEGRA returns accurate solutions in each case. This verifies that each transport theory has been implemented correctly, though it does not prove that the transport theories are valid for problems of interest at Sandia. A validation study will be presented in a future report.
