In this paper, a new neutron kinetics solver for cylindrical R-Z geometry, CYNOD, is presented the simulation of coupled transient problems pebble bed reactors. The code utilizes Direct Coarse Mesh Finite Difference method, in which set one-dimensional equations each transverse direction solved by means analytic Green’s function method. A method that deals with control rod cusping also presented. heterogeneous fuel kernel model implemented order to accurately take into account Doppler...
In this paper, the development is presented of a splitting method that can efficiently solve coarse-mesh discretized low-order quasi-diffusion (LOQD) equations. The LOQD problem reproduce exactly transport scalar flux and current. To equations efficiently, proposed. splits into two parts: (a) D captures significant part solution in central parts assemblies be reduced to diffusion-type equation (b) Q accounts for complicated behavior near assembly boundaries. Independent discretizations are...
In this paper, we develop a homogenization methodology for the two-dimensional low-order quasi-diffusion equations full-core reactor calculations that is based on family of spatially consistent coarse-mesh discretization methods. The solution generated by these methods preserves number spatial moments fine-mesh transport over each assembly. proposed method reproduces accurately complicated large-scale behavior within assemblies. To demonstrate performance developed methodology, present...
