ENCLOSURE TO SBK-L-05130

NRC Bulletin 2004-01 Sixty (60) Day Report FPL Energy Seabrook submits this report pursuant to NRC Bulletin 2004-01, Inspection ofAlloy 82/182/600 Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized-Water Reactors dated May 28, 2004.

This report is being submitted within (60) days of plant restart from refueling outage OR10 on May 3, 2005.

Paragraph 2 (a) in Requested Information of Bulletin 2004-01 states in part, Within 60 days of plant restart following the next inspection of the Alloy 82/182/600 pressurizer penetrations and steam space piping connections, the subject PWR licensees should:

(a) submit to the NRC a statement indicating that the inspections described in the licensee's response to item (1)(c) of this bulletin were completed and a description of the as-found condition of the pressurizer shell, any findings of relevant indications of through-wall leakage, followup NDE performed to characterize flaws in leaking penetrations or steam space piping connections, a summary of all relevant indications found by NDE, a summary of the disposition of any findings of boric acid, and any corrective actions taken and/or repairs made as a result of the indications found.

In response to paragraph (1)(c), FPLE Seabrook committed to perform a 100% bare metal visual (BMV) examination (VT-2) on five (5) steam space nozzles and one (1) surge nozzle on the Pressurizer, which possess Alloy 82/182 weld metal.

Inspection Performed A bare metal visual (BMV) examination (VT-2) of each (5) steam space piping connection and (1) surge line piping connection to the Pressurizer was performed.

Extent of Examination A 3600 visual examination, using VT-2 visual examination criteria, of 6 Pressurizer Alloy 82/182 piping connections looking for evidence of pressure boundary leakage.

Inspection Method A direct VT-2 visual examination was performed using certified VT-2 examiners.

Supplemental lighting was used to highlight areas of interest. Illumination was verified for the direct visual examination at maximum working distance. Verification was made using an ASME Section XI near distance vision test chart for VT-2 examination.

As-Found Condition None of the 6 Pressurizer Alloy 82/182 piping connections exhibited evidence of pressure boundary leakage. Two of the steam space nozzles appeared to have previous liquid penetrant developer remaining in the toes of the nozzle welds in a few locations.

Disposition of Developer Indication As required by the FPLE Seabrook work plan, indeterminate visual indications receive liquid penetrant examination. Liquid penetrant examination was performed on the two steam space nozzles and results were acceptable.

Corrective Actions as a Result of Indications No corrective actions were required. No evidence of pressure boundary leakage was observed.
