Summary:

The EQUIPOISE program for two-dimensional two-group calculations in R-Z geometry can now be used to compute adjoint fluxes and integrals associated with them. In addition, certain improvements were made to increase convergence rates in one-dimensional problems, to prevent excessive running times and input errors, and to eliminate redundant tape movements. The WHIRLAWAY code for two-group three-dimensional calculations is described. The program was constructed as a prototyne for a future code for the IBM-7096. Cartesian co-ordinates are the only geometry, and the maximum number of mesh points are 6 x 8 x 8. The boundary conditions may be either zero flux or zero derivative, and material distributions are arbitrary. The rate of convergence is found to be significantly greater than that found for the analogous problem using a two-dimensional program. (auth)
