A theoretical model of the variational nodal method was established by using Galerkin variational method and Ritz discretization to solve neutron diffusion equations. Based on this model,a computational code named VIOLET was developed for computation of three-dimensional Cartesian geometry reactor cores.The code was used to calculate a PWR core problem without discontinuity factors and a BWR core problem with discontinuity fac-tors.The results indicate that the code is feasible and reliable.
