SUBJECT:
BULLETIN 2004-01, "INSPECTIONS OF ALLOY 82/182/600 MATERIALS USED IN THE FABRICATION OF PRESSURIZER PENETRATIONS AND STEAM SPACE PIPING CONNECTIONS AT PRESSURIZED-WATER REACTORS," RESPONSE FOR ST. LUCIE NUCLEAR PLANT, UNITS 1 AND 2 (TAC NOS. MC3505 AND MC3506)
Dear Mr. Stall:
On May 28, 2004, the U.S. Nuclear Regulatory Commission (NRC) issued Bulletin 2004-01, "Inspections of Alloy 82/182/600 Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized-Water Reactors," to the industry. 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 that will be performed to verify the integrity of the pressurizer penetrations and steam space piping connections.
By a letter dated July 27, 2004, as supplemented by letters dated January 18, 2005, and July 14, 2006, Florida Power and Light Company (FPL) provided its responses to items 1a, 1b, 1c and 1d of Bulletin 2004-01 for the St. Lucie Nuclear Plant, Units 1 and 2. FPLs responses described its materials of fabrication and past, current and future pressurizer penetrations and steam space piping inspection programs at St. Lucie.
FPLs 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.
This reply required you to provide further responses to the remaining items in the bulletin.
In response to item 1b, FPL described prior inspections and inspection results of pressurizer penetrations and steam space piping connections that had been performed at St. Lucie. FPLs response included the basis for concluding that St. Lucie satisfies the applicable regulatory requirements related to the integrity of pressurizer penetrations and steam space piping connections.
J. Stall January 11, 2007 In response to item 1c in the bulletin, FPL indicated that the St. Lucie Unit 1 pressurizer would be replaced during the fall 2005 refueling outage and that Alloy 82/182/600 materials would not be used in any of the replacement pressurizer penetrations. Subsequent examinations of the replacement pressurizer will follow the required American Society of Mechanical Engineers Code Section XI inspection plan. FPLs July 14, 2006, letter confirmed that the pressurizer had been replaced.
In the response to item 1c for St. Lucie Unit 2, FPL provided a description of the Alloy 82/182/600 pressurizer penetration and steam space piping connection inspection program that would be implemented 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 St. Lucie Unit 2 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, FPL indicated that follow-up nondestructive examination (NDE) will be performed to characterize flaws in the leaking penetrations. FPL 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 in the bulletin, FPL 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 reactor coolant pressure boundary at St. Lucie Units 1 and 2 and for meeting all applicable regulatory requirements that pertain to the St. Lucie facility.
By letter dated April 15, 2005, you provided a response to item 2a in 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 the SL2-15 refueling outage at St. Lucie Unit 2 and a description of the as-found condition of the locations inspected was provided. FPL also described any findings of relevant indications of through-wall leakage and follow-up 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 a description of any corrective actions taken and/or repairs made as a result of the indications found was also provided in this letter. Since the Unit 1 pressurizer had been replaced according to the schedule provided in response to item 1c, no response to item 2a was required for Unit 1.
The NRC staff has completed its activities associated with the review of FPLs responses to Bulletin 2004-01 for St. Lucie Units 1 and 2 and finds FPLs response to be acceptable. It should be noted that industry commitments or staff regulatory actions may result in the need for FPL to modify its plans for the inspection and repair of items discussed in Bulletin 2004-01. It is the staffs expectation that you will revise your plan for the inspection and repair of items discussed in Bulletin 2004-01 consistent with other industry commitments or staff regulatory actions.
J. Stall January 11, 2007 This closes the staffs efforts with regard to the review of the Bulletin 2004-01 response for St. Lucie Units 1 and 2.
Please contact me at (301) 415-3974 if you have any questions on this issue.
Sincerely,
/RA/
