EFFECTS OF VERTICAL GRAVITY OSCILLATIONS ON PERFORMANCE OF THE T7 NATURAL CIRCULATION BOILING WATER REACTOR

This report presents results from an analog computer study of the effects of vertical gravity oscillations on the performance of a natural circulation boiling water reactor propulsion system in a T7 tanker under conditions of a ship's motion. Ship's motion was simulated as a sinusoidal variation in vertical accleration. The response of the reactor model was determined including flow, void content, reactivity, power fuel temperature, and reactor stream pressure. Void reactivity, frequency response, and the thermal-hydraulic model are discussed. Equations, numerical values, and nomenclature are presented. The results show that the T7 reactor, as designed, would operate successfully at 100% power during ship's motion. A schematic diagram of the analog computer is included.
