Description

We discuss in this paper the efficiency of approximate discrete ordinates (SN) albedo boundary conditions for one-speed eigenvalue problems in X,Y-geometry. The SN albedo matrix substitutes approximately the reflector around the multiplying medium, as we neglect the transverse leakage terms within the reflector region. By efficiency we mean analyzing the accuracy of the numerical results versus the CPU execution time of each run of a given model problem. Numerical results to a typical test problem are shown to illustrate this efficiency analysis. (author)
