The internationally circulated Pool Critical Assembly (PCA) Pressure Vessel Benchmark was analyzed using the PENTRAN Parallel Sn code system for the geometry, material, and source specifications as described in the PCA Benchmark documentation. This research focused on utilizing the BUGLE-96 cross section library and accompanying reaction rates, while examining both adaptive differencing on a coarse mesh basis as well as Directional Theta Weighted Sn differencing in order to compare the calculated PENTRAN results to measured data. The results show good comparison with the measured data as well as to the calculated results provided from TORT for the BUGLE-96 cross sections and reaction rates, which suggests PENTRAN is a viable and reliable code system for calculation of light water reactor neutron shielding and dosimetry calculations.
Christopher Edgar became a graduate student in the Nuclear and Radiological Engineering Program at Georgia Tech in January of 2011 after transferring from the department of Nuclear and Radiological Engineering at the University of Florida. His research focuses on computational transport and encompasses projects in reactor physics benchmarking, fuel burnup and depletion, and detection. Mr. Edgar received his B.S. degree in Nuclear Engineering (2010) from the University of Florida, Gainesville, FL.
