PERFORMANCE HIGHLIGHTS
~ Achieved INPO 1 evaluation.
~ "Most improved nuclear plant during the 3 year period 1992-1994,"
American Nuclear Society, May 1995.
~ Nuclear Division completed 1994 with highest availability (82%)
in FPL history, despite four refueling outages.
~ Setting dual unit record run (141 days as of August 28, 1995)
~ Continued success in achieving shorter refueling outages that have resulted in reliable unit operation.
~ Continued reduction in station operating cost achieved with continued safe and reliable unit operation.

RADWASTE MINIMIZATIONPLAN Strategic Task Team formed in 1994 to reduce generation of Radwaste.
Crossfunctional team, sponsored by Maintenance Manager Raised general plant awareness of Radwaste The plant is generating an average of 50 cubic feet per week, which reflects a 70% reduction in Radwaste volume.
Shipped first 1995 Radwaste shipment in late June.
Estimate only 3 SeaVan shipments in 1995.
Total projected cost for 1995 SeaVan shipments is $450,000.00.
1994 shipment cost was $2,000,000.00.
Exposure is down, contaminated floor space is down, radwaste generation is down.

GRASS INTRUSION Results of Review
- 1. Cooling Canal maintenance activities are adequate Clearing of berms Trimming embankment toes Mechanical grass removal
-'Annual thermal efficiency study 36
GRASS INTRUSION Results of Review 2.
Screen Wash System Performance.
Screen Wash Pump performance satisfactory Screen Wash Strainers clogged Spray nozzles partially clogged Deflector plates eroded
GRASS INTRUSION Results of Review 3.
Intake Cooling Water Strainer Backwash Strainers required frequent mechanical cleaning/backwashing Difficultto determine which strainer to clean Trend of cleaning had been increasing over several years No corresponding change in canal conditions 38
GRASS INTRUSION Corrective Actions
~ Cleaned Screen Wash Spray Nozzles
~ Established criteria to monitor Screen Wash Strainers
