CORN PONE: A MULTIGROUP, MULTIREGION REACTOR CODE
Corn Pone is an Oracle multigroup, multiregion, onedimensional P/sub 1/ reactor code for slab, cylindrical, or spherical geometry. The numbers of groups and space points are not limited for practical purposes. There may be 128 regions each having its own epithermal and thermal groups. The equations -reduce simply to Diffusion Theory equations and slowing down may be treated by Fermi, Wigner, or Goertzel-Greuling kernels. Disadvantage factors may be computed and applied. Regions and element events, sources, cross sections, flux spatial integrals, fluxes and currents may be edited, that is, individually extracted from the program and printed or displayed. Running time is 6 minutes per iteration for a 32-group, 2-region, and 56-space point case. Averaged cross sections may be put directly on the Corn Pone Group Constant Tape or cross section graphs may be stored on tape and then integrated over a specified group structure. Infinite, homogeneous medium, P/sub 1/ age and Fourier transform codes are available and require 5 minutes to punch values for 31 groups. The development of the theory from a set of differential equations to a set of difference equations suitable for machine computations is traced, complete instructions for use are given, and finally, methods and approximations used in the code are evaluated.
