Abstract: POW is a 'workhorse' module of the AUS system and is used mainly for the following applications: (1) 2 region resonance theory data preparation from presently available fast reactor 26- or 16-group libraries, (2) 0, 1 and 2D diffusion calculations - eigenvalue or criticality search, source or feedback-free kinetics calculations, and (3) perturbation calculations. Main features of the code include the following: (1) it will run under the site AUS system or stand alone (on an IBM360/50), (2) the code uses SLOR for inner iterations with region rebalance to enhance convergence, Gauss-Seidel for upscatter iterations with group rebalance to enhance convergence, Chebyshev source extrapolation for outer iterations and a delayed neutron integrated Crank-Nicholson method for kinetics problems, (3) free format style of input is used throughout, and (4) output options include 1 and 2D flux or reaction rate plots (on a CALCOMP plotter).
