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).
