High Pressure Injection Pump Modification
- Background
- Identified an issue that fine debris could impact the existing internal pump clearances
- Selected Approach
- Modify the existing pump to add internal strainer to prevent debris from entering hydrostatic bearing
- This will allow the pumps to perform all design functions without replacement
- Project Milestones
- Strainer design and testing
- Pump performance validation
- Field implementation 27 Davis-Besse ar Power Station June 3, 2003
High Pressure Injection Pump Modification
- Strainer Design and Testing
- Strainer allows water to pass through and supply the hydrostatic bearing and seal
- flushes strainer surface
- Relocate ports that supply water to the hydrostatic bearing
- supported by testing performed by pump manufacturer, Pump Guinard of France
- reduce debris concentration at strainer
- MPR Associates performing design work
- mock-up testing at Wyle Labs to verify performance 28 Davis-Besse ar Power Station June 3, 2003
High Pressure Injection Pump Modification 29 Davis-Besse ar Power Station June 3, 2003
High Pressure Injection Pump Modification
