•Project Status– Modification design concept is
complete• Stress and hydraulic design analyses
complete• Failure Modes and Effects analysis under
review
– In-plant testing satisfactorilycompleted
– Initial assumptions for testing set– Mock-up testing in progress– Pumps disassembled awaiting
modifications

July 9, 2003Davis-BesseNuclear Power Station
22
Preliminary Findings•Strainer design with 90 mil holes operated satisfactory (noplugging), 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 notfill bearing pads, but hard debris 12 mil in size caused shaftsleeve wear
•Debris (primarily fiber) became lodged part way throughclearances in wear fixtures, forming a debris pad or mat thatcaused local wear of softer material due to high contact force
•Initial findings indicate conditions more closely modelingexpected containment environment is warranted

Hydrostatic Bearing Design
July 9, 2003Davis-BesseNuclear Power Station
24
Hydrostatic Bearing Configuration
July 9, 2003Davis-BesseNuclear Power Station
25
Pump Guinard Design Change•French and Davis-Besse pumps have difference that impactdebris operation
– 4500 rpm operation increases centrifugal effect reducing debrisconcentration 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, 2003Davis-BesseNuclear Power Station
26
Project Completion Plans
• Pump modification continues to be main successpath
• Revise initial assumptions to more closely modelactual containment environment
• Continue testing• Refine modifications as necessary• Determine final resolution

DEFINITION This indicator depicts the number of First-Aid and OSHA Recordable incidents for DB Maintenance Section In-House Employees. 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.
