Abstract
Variational nodal methods are extended to treat multigroup and criticality problems and are implemented as a module for the production code DIF3D at Argonne National Laboratory. New within-group solution algorithms based on the partitioning of the response matrix equations result in computing times that are comparable to those obtained with a widely employed nodal transport method. Accuracy and timing comparisons are made for three few-group criticality problems in X-Y geometry.
