An Analog Computer Model of a Multiple-Region Reactor
ANL-6482 is a 1962 Argonne National Laboratory technical report describing an analog computer technique for solving the time-space-dependent neutron diffusion equation for a multiple-region reactor. The method handles fuel burnup, fission product and xenon-iodine poison buildup, and control poison injection while maintaining constant power, using interregion neutron diffusion expressed as a surface integral to achieve accurate flux plots with only six spatial points. Complete circuit diagrams, potentiometer settings, scaled equations, and comparison with digital results are provided.
