July 9, 2003 Davis-Besse Nuclear Power Station 20 High Pressure Injection Pump Modification Update Mock-Up Testing
July 9, 2003 Davis-Besse Nuclear Power Station 21 Mock-Up Test Fixtures High Pressure Injection Pump Modification Update
July 9, 2003 Davis-Besse Nuclear Power Station 22 Preliminary Findings
- Strainer design with 90 mil holes operated satisfactory (no plugging), however
- Debris through 90 mil strainer filled hydrostatic bearing pads (soft debris was not ground up)
- Sieved debris (to simulate strainers with smaller holes) did not fill bearing pads, but hard debris 12 mil in size caused shaft sleeve wear
- Debris (primarily fiber) became lodged part way through clearances in wear fixtures, forming a debris pad or mat that caused local wear of softer material due to high contact force
- Initial findings indicate conditions more closely modeling expected containment environment is warranted
July 9, 2003 Davis-Besse Nuclear Power Station 23 Hydrostatic Bearing Design
July 9, 2003 Davis-Besse Nuclear Power Station 24 Hydrostatic Bearing Configuration
July 9, 2003 Davis-Besse Nuclear Power Station 25 Pump Guinard Design Change
- French and Davis-Besse pumps have difference that impact debris operation
- 4500 rpm operation increases centrifugal effect reducing debris concentration at new hydrostatic bearing supply take-off
- Hydrostatic bearing AND shaft sleeve hardfaced
- Labyrinth seals between stages instead of wear rings
- French pump modifications slightly different
- Hydrostatic bearing supply take-off on discharge side of impeller instead of suction
- Used discharge side seal as strainer
- Installed hydrostatic bearing instead of central volute bushing (for rotordynamics)
- Modified hydrostatic bearing pads for no supply flow conditions
July 9, 2003 Davis-Besse Nuclear Power Station 26 Project Completion Plans
- Pump modification continues to be main success path
- Revise initial assumptions to more closely model actual containment environment
- Continue testing
- Refine modifications as necessary
- Determine final resolution

OBJECTIVE/GOAL The objective is to prevent industrial accidents by careful work planning, supervisory involvement, and employee attention to detain and thoughtful work practices.
ANALYSIS There were 2 first-aid injuries in the Maintenance section for the month of June.
The First-Aid recordable rate was 10.12 per 200,000 work-hours for the month of June with a 12-month rolling average of 2.51.
The OSHA recordable rate was 0.00 per 200,000 work-hours with a rolling average of 0.82.
THE ERROR RATES ARE CURRENTLY BEING ESTIMATED BY AVERAGING THE WORK-HOURS OVER THE LAST 5 MONTHS.
