SUBJECT:
SEABROOK STATION, UNIT NO. 1 - RESPONSE TO BULLETIN 2004-01, INSPECTION OF ALLOY 82/182/600 MATERIALS USED IN THE FABRICATION OF PRESSURIZER PENETRATIONS AND STEAM SPACE PIPING CONNECTIONS AT PRESSURIZED-WATER REACTORS, (TAC NO. MC3511)
Dear Mr. St. Pierre:
On May 28, 2004, the U.S. Nuclear Regulatory Commission (NRC) issued Bulletin 2004-01, Inspection of Alloy 82/182/600 Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized-Water Reactors (Agencywide Documents Access and Management System (ADAMS) Accession No. ML041480034) This bulletin informed addressees that current methods of inspecting the pressurizer penetrations and steam space piping connections fabricated from Alloy 82/182/600 materials may need to be supplemented with additional measures (e.g., bare-metal visual inspections) to detect pressurizer penetration and steam space piping connection flaws or leakage. The bulletin requested that addressees provide the NRC with information related to the materials of construction, the inspections that have been performed, and the inspections which will be performed to verify the integrity of the pressurizer penetrations and steam space piping connections.
By a letter dated July 27, 2004 (ADAMS Accession No. ML042110132), as supplemented by letter dated January 18, 2005 (ADAMS Accession No. ML050210171), FPL Energy Seabrook, LLC (FPLE), provided responses to items 1a, 1b, 1c and 1d of Bulletin 2004-01 for Seabrook Station, Unit No. 1 (Seabrook). FPLEs responses described its materials of fabrication and past, current and future pressurizer penetrations and steam space piping inspection programs at Seabrook.
FPLEs response to item 1a reported that some of the materials used in the fabrication of the pressurizer penetrations and steam space piping connections were Alloy 82/182/600 materials.
An affirmative reply to item 1a required you to provide further responses to the remaining items in the bulletin.
In response to item 1b, FPLE described prior inspections and inspection results of pressurizer penetrations and steam space piping connections which had been performed at Seabrook.
FPLEs response included the basis for concluding that Seabrook satisfies the applicable regulatory requirements related to the integrity of pressurizer penetrations and steam space piping connections.
G. St. Pierre In response to item 1c, FPLE provided a description of the Alloy 82/182/600 pressurizer penetration and steam space piping connection inspection program that will be implemented at your plant during the next and subsequent refueling outages. The description included the items to be inspected; the percent coverage that would be performed at each location; the inspection methods to be used; the qualification standards for the inspection methods and personnel; the process used to resolve any inspection indications; the inspection documentation to be generated; and the basis for concluding that your plant will satisfy the applicable regulatory requirements related to the structural and leakage integrity of pressurizer penetrations and steam space piping connections. If leaking pressurizer penetrations or steam space piping connections are found, FPLE indicated that follow-up nondestructive examination (NDE) will be performed to characterize flaws in the leaking penetrations. FPLE provided its plans for expansion of the scope of NDE to be performed if circumferential flaws are found in any portion of the leaking pressurizer penetrations or steam space piping connections.
In response to item 1d, FPLE explained why the inspection program identified in the response to item 1c in the bulletin is adequate for the purpose of maintaining the integrity of the Seabrook reactor coolant pressure boundary (RCPB) and for meeting all applicable regulatory requirements.
By letter dated January 4, 2007 (ADAMS Accession No. ML070100538), you provided a response to item 2a of bulletin 2004-01. This letter provided a statement to the NRC indicating that the inspections described in your response to item 1c of the bulletin were completed during a recent Seabrook outage and a description of the as-found condition of the locations inspected was provided. This letter stated that no indications of pressure boundary leakage were identified.
G. St. Pierre The NRC staff has completed its activities associated with the review of FPLEs responses to Bulletin 2004-01 and finds FPLEs response to be acceptable. It should be noted that industry commitments or staff regulatory actions may result in the need for you to modify your plans for the inspection and repair of items discussed in Bulletin 2004-01. For example, specific actions addressed in topical report MRP-139, "Materials Reliability Program: Primary System Piping Butt Weld Inspection and Evaluation Guideline" and/or plant-specific Confirmatory Action Letters regarding dissimilar metal butt welds encompassed by Bulletin 2004-01 may exceed the scope of actions addressed in your response to Bulletin 2004-01. The NRC staff will continue to monitor the industrys actions associated with Alloy 82/182/600 pressurizer penetration and steam space piping connections and may take additional regulatory actions as appropriate.
This closes the staffs efforts with regard to the review of the Bulletin 2004-01 response for Seabrook. Please contact me at (301) 415-2481 if you have any questions on this issue.
Sincerely,
/ra/
