June 3, 2003 Davis-Besse Nuclear Power Station 26 High Pressure Injection Pump Modification and Corrective Action Program Performance Bob Schrauder Director -Support Services
June 3, 2003 Davis-Besse Nuclear Power Station 27 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
June 3, 2003 Davis-Besse Nuclear Power Station 28
- 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 High Pressure Injection Pump Modification
June 3, 2003 Davis-Besse Nuclear Power Station 29 High Pressure Injection Pump Modification
June 3, 2003 Davis-Besse Nuclear Power Station 30
- Pump Performance Validation
- Rotordynamics analysis performed to predict satisfactory pump operation
- includes worn condition after debris service
- In-plant testing is being performed to validate rotordynamics model
- Post-modification testing will be performed prior to returning the pumps to service High Pressure Injection Pump Modification
June 3, 2003 Davis-Besse Nuclear Power Station 31
- Field Implementation
- Both pumps must be removed; each weighs 6,000 pounds
- Removal of HPI pump 2 requires detailed planning due to its location in the Emergency Core Cooling Pump Room
- A team involving six different craft disciplines will be used to remove the pumps and interference
- Design and Plant Engineering are key groups involved with the removal plans High Pressure Injection Pump Modification
