Pathfinder Atomic Power Plant Analog Simulator.
The steady-state and dynamlc characterlstics of the Pathfinder systems were simulated on a dual-console Pace Analog Computer. The derivation of the system equations, the assumptions involved, their numerical evaluation, and their conversion to analog circuitry are described. The Pathfinder system is unique because of the internal nuclear superheater, and controlled, forced recirculation. In simulating this system the following major assumptions were maden the reactor is a boiling-water type; moderated and cooled with saturated, light water; pressurized between 400 and 800 psiai and has a neutron flux distribution that is spatially invariant. All the importanit non-linearities are retained, thus permitting accurate solutions of large system disturbances. The neutron kinetics equations, with their six groups of delayed neutrons, are simulated with power feedbacks through reactor pressure, steam flow, core inlet subcooling, and fuel- element temperature. Particular attention ls devoted to the accurate simulation of fuel-element heat transfer; the reactor pressure-control system, which operates the turbine inlet valves; and the effect of core inlet subcooling, sinee these were found to have pronounced effects on reactor performance. The transient temperatures at the superheater hot spot and exit are generated. Enough flexibility ss included, so that all important disturbanees possible in the actual plant can …

Photograph taken for a story in the Daily Oklahoman newspaper. Caption: "When women walk into the shoe shop of William Cherry and are greeted, "good morning, pretty lady," some become indignant, others smile. Almost immediately they learn the voice comes from an improvised tree, sheltered in a corner of the shop. It is from this location that 'Jasper' greets customers daily. Not an ordinary parrot, Jasper can trace his ancestry back to more than 100 years ago, and has his master to thank for his existence."
