e Abstract This report details the pressure testing of selected ASME Class 1, 2 and 3 piping and components of Florida Power and Light Company's Unit 3 at the Turkey Point Nuclear Power Station. These tests were performed during Unit 3 cycle 21 completed during the fall refueling outage. The refueling outage occurred between the dates of September 26, 2004 and December 2, 2004. The complete cycle 21 was from March 28, 2003 to December 2, 2004. This pressure testing is being reported following the first outage of the first period for fourth ten-year interval for Turkey Point Unit 3.

Piping and components were selected and tested in accordance with Section Xl of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code "Rules for Inservice Inspection of Nuclear Power Components",

1998 Edition, 2000 addenda with specific relief as granted under 10 CFR 50.55a.

Procedures The following Florida Power and Light (FPL) procedures and documents have been implemented to provide instructional guidance for the performance of the required ASME Xl pressure testing and subsequent inspections.

Test Package Development The specific pressure test boundaries were selected after review of the applicable plant Operating diagram/code boundary drawings. The piping systems were broken into sub systems. The sub-systems were selected based on Technical Specifications operability requirements, acceptable isolation points and availability of test connections and vent valves. The sub-systems were then assigned test package numbers, which could be tested in entirety, or based on availability could be broken down further into numerous tests within the specific sub-system.

The pressure test package numbers contain six (6) segments of information, Sample:

BOLTED JOINT EXAMINATIONS The bolted joint examinations were performed in accordance with 3-OSP-045.1 and 3-OSP-045.2 for ASME Class 1 and 2 components. The inspections for both class I and 2 components consisted of all normally insulated bolted connections.

The class 2 items were also limited to only those components located inside the containment. The insulation was removed for inspection. The inspections identified two bolted connections that had evidence of leakage. They are listed below with the corresponding condition report number. All leakage was evaluated by engineering as required by ASME Xl.
