Westinghouse has employed a nodal code, PALADON, for core design for many years. The code has been used in conjunction with a fine-mesh finite difference code to provide benchmarking of power distribution and, if necessary, a basis for albedo adjustments. An Advanced Nodal Code (ANC) has been developed employing the nodal expansion method for nodal coupling coefficients, the equivalence theory for cross-section homogenization, and a group theory method for pin power recovery. This methodology enables the use of a single three-dimensional core model for all design applications and eliminates the need for development of redundant core models for benchmarking and albedo adjustment. A key factor to the success of the ANC is its accurate and efficient prediction of the local pin power and thimble flux.
