TESTING OF HNPF FREEZE-SEAL PUMP

>A centrifugal pump performed adequately at a flow rate of 7200 gpm of 945 gas-cooled F sodium at a 150-ft head. A two-region freeze seal was developed and used successfully as a shaft seal on this pump. The results indicate that this pump could perform satisfactorily in the Hallam Power Reactor. (auth

EXPERIMENTAL MEASUREMENTS OF THE SUCTION HEAD REQUIRED BY THE HALLAM PROTOTYPE FREE SURFACE SODIUM PUMP

Hydraulic tests were made on the Hallam Prototype Free-Surface Sodium Pump to determine the net positive suction head (NPSH) required at various sodium flow rates. Pump performance data were also collected. The results indicate that an NPSH of 22 ft sodium is required at the design flow rate of 7200 gpm at approximates 1000 deg F, agreeing with computed values, and that the pump is designed with a safety margin of slightly over l0%.
