COUPLE - Functional Modules

COUPLE is used in the SCALE analytic sequences to update ORIGEN-S libraries with flux-weighted cross sections provided by XSDRNPM. COUPLE uses the multigroup fluxes from XSDRNPM to calculate THERM, RES, and FAST, the spectral parameters used in ORIGEN-S. This calculation is done in a manner that is consistent with the use of the data in the ORIGEN-S library for those nuclides that are not being updated with weighted cross sections from XSDRNPM.  COUPLE can also be used to create and/or update binary libraries for ORIGEN-S.
