An weighted diamond difference approximation for improving 3-D coarse mesh SN calculations
Description
An improved coarse-mesh three-dimensional (hexagonal-Z) discrete ordinates transport calculation method has been developed. This method employs an weighted diamond difference approximation, the weight in which is a function of neutron direction and scaler flux, and can be easily incorporated into conventional discrete ordinates transport codes. Results obtained from hexagonal fuel assembly calculations of high conversion reactors and fast reactor core calculations indicate that the errors of keff and power distribution are remarkably reduced by the present method
