Abstract
Previous work focused on the use of automated variance reduction parameters for use in a fixed source reactor shielding problem to solve for ex-core particle transport results. The current work assesses that strategy in light of a fully-coupled Monte Carlo problem run as a critical system with parallel processing and the use of moderate variance reduction parameters set manually. The results from the two strategies compare well. Also, results are compared between the MCNP, Virtual Environment for Reactor Applications (VERA) and Shift computer codes. Shift and VERA deliver similar results and compare well to MCNP. Scott Mosher of Oak Ridge National Laboratory assisted with questions on ADVANTG input, and Philip Tufts of Duke Energy spent long hours reviewing every input of the Harris Nuclear Plant base calculations. We appreciate the dedication and assistance.

The authors would also like to acknowledge the development and user support provided by the Exnihilo and MPACT code development teams.
