The study on spatial homogenization parameters based upon equivalence theory

Homogeneous parameters of a mathematical nuclear core full power steady state were built based on the equivalence theory upon the Canada Pickering a CANDU reactor. The reactor core neutronics is based on a two energy group formulation and a typical spatial discretization employs one node per fuel assembly, each of the assemblies is further subdivided into 12 to 30 axial slices which is sufficiently detailed to account for the non-uniform aspect of reactor core composition. This provides us a good reference solution from which all the nodal nuclear parameters can be calculated. The detailed homogeneous parameters are got which can be a reference as the nodal diffusion methods to resolve the homogeneous parameters problem.
