Abstract
Several finite element formulations of nodal schemes for neutron diffusion problems are presented: they include nonconforming primal formulations as well as mixed and mixed-hybrid ones, with exact or approximate evaluation of the matrix coefficients. These different formulations are compared between them and related to well-known point-centered and mesh-centered finite difference schemes. Some numerical results are given in one and two dimensions with different schemes. Applications to two dimensional neutron transport problems are also proposed through the general approach of tranverse integration.
