ARMP-02 documentation: Part 2, Chapter 2: Description of the CELL-2 fast and thermal cross-section libraries: Computer code manual

Technical Report ·
OSTI ID:5836867

This chapter describes the multigroup fast (GAM) and thermal (THERMOS) cross section libraries generated for use with the ARMP-02 codes CELL-2 and EPRI-PRESS. Two sets of libraries are described. The first set referred to as ''Production libraries'' is basically the same as the GAM/THERMOS libraries distributed as part of the original ARMP release for use with the EPRI-CELL code, thus the appropriate documentation from the ARMP computer code manual (EPRI-CCM 3) is reproduced here. The second set of libraries is derived from the national standard data file: ENDF/B-V. The differences between this data and earlier versions of ENDF/B are summarized. This chapter also provides information on the energy group structures used by both sets of libraries, the prompt fission neutron spectra for uranium-235 and plutonium-239, the delayed neutron fractions (yields and decay constants) and the composition of mixed materials. 10 refs., 8 tabs.
