INVESTIGATION OF TYPES OF SEALS FOR MAIN COOLANT PUMPS FOR LARGE PRESSURIZED WATER REACTOR NUCLEAR PLANTS

Comparative reliability and installion and operating costs of canned-motor and controlled-leakage pump designs are determined for application in a pressurized-water reactor. Data accumulated by consultation yielded the manufacturers' capability to produce pumps with specifications of 30,000-40,000 gpm flow range, 1500-2500 psig system operating pressure, 40-150 foot total dynamic head, and 1800 rpm. Initial and operating costs of both pump types in 1960 and 1965 are based upon constant dollars. Findings indicate production capability of reliable canned-motor pumps of 40,000 gpm capacity is possible for 1960; controlled-leakage pumps of similar capacity and reliability are not available. Manufacturers' seal research and development programs are inadequate due to limited research appropriations and lack of significant sales potential. Estimated pump cost reductions, and recommended research and development programs with cost schedules and estimates are presented.
