Docket Nos.

50-250 and 50-251 Inservice Ins ection Pro ram This letter documents Florida Power and Light Co.'s (FPL) decision to invoke Code Case N-416, "Alternative Rules for Hydrostatic Testing of Repair or Replacement of Class 2 Piping," as discussed in Regulatory Guide (RG) 1.147 foz the Class 2 component steam generators up to the first isolation valve.

Attached Figures 1 through 6 define the steam generators'oundary for applicability of Code Case N-416 for Turkey Point Units 3 and 4.

There will be no deviations from the requirements of. Code Case N-416.

By FPL letter L-93-60, dated March 10,

1993, FPL informed the NRC that the Turkey Point Units 3 and 4 Insezvice Inspection Program invokes Code Case N-498, "Alternative Rules for 10 Year Hydrostatic Pressure Testing for Class 1 and 2 Systems,Section XI, Division 1," as discussed in RG 1.147.

Code Case N-498 requires a hydrostatic pressure test after replacement and repairs for Class 1 and 2 systems.

Ultrasonic inspections were conducted on the Turkey Point Unit 4 steam generators'eedwater nozzle to reducer weld joints.

The inspections identified cracks originating in the weld root and propagating into the reducer base material for all three steam generators.

FPL is currently replacing the Turkey Point Unit 4 feedwater reducers on all three steam generators.

Code Case N-416 allows deferral of the required hydrostatic pressure test for repairs or replacements to the next regularly scheduled ten-year hydrostatic test The ten-year hydrostatic pressure test for the Turkey Point Unit 3 steam generators was completed on September 24, 1992.

The ten-year hydrostatic pressure test for the Turkey Point Unit 4'steam generators was completed on April 18, 1993.

The next scheduled ten-year hydrostatic pressure test will be performed at the end of the third inspection interval for each unit.

The end of the third inspection interval for Turkey Point Unit 3 is February 21, 2004.

The end of the third inspection interval for Turkey Point Unit 4 is April 15, 2004.
