MINER: Three-Dimensional Multi-Group Finite-Difference and Nodal Method for CANDU® Applications

Abstract

A new flux-solver code named MINER Solver has been developed in order to overcome some of the built-in limitations of the RFSP core-analysis code. The MINER code includes both a finite-difference solver and a nodal method solver. Both solvers have multi-group capabilities with ADFs (Assembly Discontinuity Factors). The MINER code can be used independently to solve benchmark problems, or can be used with RFSP to solve full-core problems. In this paper, the accuracy of the MINER code is demonstrated by using it to solve a set of standard benchmark problems with both the FDM (Finite-Difference Method) and the nodal method.
