THE PN METHOD FOR CELL CALCULATIONS OF PLATE-TYPE FUEL ASSEMBLIES

An implementation of the PN method for determining the effective multiplication factor and the neutron scalar flux and current in plate-type fuel cells is reported. Computational aspects of the method are discussed and numerical results are given for a three-region problem with group constants defined in a 64-group structure. The PN results are found to agree quite well with results obtained using the ANISN code.
