title = "A hybrid diffusion/transport method",
abstract = "A hybrid diffusion/transport method is presented in this paper. The traditional diffusion theory is used for regions where the diffusion approximation is valid, while response functions precomputed by a local transport solver are used for non-multiplying regions or regions with strong heterogeneities, where diffusion theory breaks down. The two methods are coupled through the 0-th and 1st moments of the partial angular flux on the interface between the diffusion and transport nodes (coarse meshes). The hybrid method was implemented and tested on a one dimensional BWR benchmark problem. This test has shown that the hybrid method can achieve high accuracy while maintaining a computational efficiency comparable to the pure diffusion methods.",
