ETOE-2/MC/sup 2/-2/SDX multigroup cross-section processing

The ETOE-2/MC/sup 2/-2/SDX multigroup cross-section processing codes were designed to provide a comprehensive neutron cross-section processing capability for a wide range of applications including critical experiment analysis and core design calculations. Fundamental nuclear data from ENDF/B provide the primary input to the code system, and the output consists of a user-specified CCCC ISOTXS multigroup cross-section data file. Great flexibility is provided to the user in specifying the rigor of the calculation, so that a unified cross-section processing system with a single data base which may be used for both preliminary survey scoping studies and rigorous design calculations is available. The principal program blocks of the code system include a library processor and format converter between ENDF/B data and the MC/sup 2/-2/SDX library; an ultra-fine-group fundamental-mode calculation (MC/sup 2/-2) which provides a composition-dependent spectrum calculation and broad-group collapsing capability; a rigorous hyper-fine-group, spatially hetegeneous resolved resonance calculation (RABANL) to supplement the more approximate NR approximation used in the ultra-fine-group treatment; and an intermediate group space-dependent capability (SDX). 5 figures, 4 tables.
