Sodium testing of intermediate-size inducer pump in SPTF at ETEC

The overall test program includes pump assembly, installation, testing, removal from the test loop, disassembly and final inspection of the entire pump. Testing will include checkout tests, head/flow and efficiency characterizations at selected speeds and sodium temperatures, suction performance determination, a 2000 hour design point endurance test, a 300 hour off design endurance test, and thermal transient tests. The pump will be cleaned of sodium, disassembled, and examined before the 2000 hour endurance test and after the thermal transient tests to determine the effects that long-term operation at 200 percent NPSH margin and off design operation at the same flow and NPSH have on the pump components
