Abstract:
Analytical PN and AN moment criticality solutions are obtained for uniform infinite slabs and finite
spheres using Mark, Marshak and importance-weighted vacuum boundary conditions. Comparison with
'exact' criticality results leads to reevaluation of the literature-reported 'belief' in the relative accuracy
comparisons of Mark and Marshak boundary conditions. The ranking for these problems is Mark, Marshak,
importance-weighted in order of increasing accuracy.
