Generalized bilinear weighting for multigroup cross-section collapsing

Journal Article · · Nucl. Sci. Eng., v. 57, no. 4, pp. 340-344
OSTI ID:4100870
A new multigroup cross-section collapsing procedure is described in the framework of the generalized perturbation theory. Numerical examples suggest its use, in addition to the standard linear flux and bilinear real-flux/adjoint-flux weighting procedures, when reactivity coefficients, such as the sodium void coefficient, are to be preserved in a few-group model.
