Benchmark problems for two group hexagonal geometry nodal diffusion codes
- Westinghouse Electric Corp., Pittsburgh, PA (United States)
Hexagonal nodal methods have gone through much progress now that computer codes based on these methods have substantially improved in performance and reached the same level of accuracy and computational efficiency as the square nodal codes. This development necessitated the use of good and reliable reference solutions to a variety of benchmark problems in order to adequately assess the performance of the newly developed family of codes. This paper is a step on providing documented benchmark problem reference solutions which are generated by the widely accepted and well established finite difference code DEF3D-FD. Two and three dimensional problems for a variety of hexagonal cores, including pressurized light water VVER-1000 and VVER-440 reactor cores as well as a heavy water reactor core were analyzed using very fine mesh spacings. Proper extrapolation was performed to determine reference eigenvalues and power distributions for the benchmark problems. These benchmark problems have been used to qualify the accuracy of Westinghouse advanced nodal code for hexagonal cores, ANC-H.
