This paper compares the NITAWL and CENTRM resonance processors in the SCALE code system. The cases examined consist of the International Organization for Economic Development/Nuclear Energy Agency (OECD/NEA) criticality Working Group Benchmark 20 problem. These cases represent fuel pellets partially dissolved in a borated solution. The assumptions inherent to the Nordheim Integral Treatment, used in NITAWL, are not valid for these problems. CENTRM resolves this limitation by explicitly calculating a problem-dependent point flux from point cross sections, which is then used to create group cross sections.
