Ewen, R L

The MULE program, which finds the overton modes associated with three diffusion theory eigenvalue problems is described. Overtone modes are calculated by application of the Wielandt transformation, which by use of an eigenvalue estimate allows any simple root to be isolated such that it and the corresponding eigenvector may be determined by power method iteration of the transformed matrix. In addition to finding the eigenvalues and direct fluxes for a series of modes, the MULE program calculates adjoint fluxes, adjoint weighted integrals, and various reactivity or synthesis parameters. Both slab and cylindrical geometry are included; the slab cores need not be symmetrical, and any radial-azimuthal overtone combination may be determined for cylindrical cores that are uniform azimuthally.
