Three-dimensional numerical model of neutron flux in Hex-Z geometry
Original language description
We present a method for solving the equations of neutron transport with discretized energetic dependence and angular dependence approximated by diffusion theory. Stationary solution is of interest that characterizes neutron fluxes within a nuclear reactor core in an equilibrium (critical) state. The VVER-1000 type core with hexagonal fuel assembly lattice is considered and a nodal method is used for numerical solution. The method effectively combines a whole-core coarse mesh calculation with a more detailed computation of fluxes based on the transverse integrated diffusion equations. By this approach, it achieves a good balance between accuracy and speed.
