Bezilla 419-321-7676 Vice President - Nuclear Fax: 419-321-7582 Docket Number 50-346 License Number NPF-3 Serial Number 3326 May 15, 2007 U.S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555-0001
Subject:
Davis-Besse Nuclear Power Station Request to Use Subsequent ASME Code Edition and Addenda in Accordance with 10 CFR 50.55a(g)(4)(iv)
Ladies and Gentlemen:
Pursuant to 10 CFR 50.55a(g)(4)(iv), the FirstEnergy Nuclear Operating Company (FENOC) requests Nuclear Regulatory Commission (NRC) approval to use a subsequent American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV)
Code edition and addenda to allow the use of an Electro Discharge Machining (EDM) process. The EDM process will be used to remove the thermo well material to facilitate 1 -inch pressurizer thermo well nozzle repair at the Davis-Besse Nuclear Power Station (DBNPS). ASME Section XI, 1995 Edition through the 1996 Addenda, which is the code in effect for the DBNPS, does not contain requirements for the EDM process.
Therefore, FENOC requests to use ASME BPV Code Section XI, 1998 Edition through the 2000 Addenda for the EDM metal removal process. The enclosure provides details of the request.
FENOC requests approval by November 30, 2007 to support repairs planned for the next maintenance and refueling outage, which is currently scheduled to commence in December 2007.
The Attachment, Commitment List, identifies that there are no commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. Henry L. Hegrat, FENOC Fleet Licensing Supervisor, at (330) 374-3114.
Docket Number 50-346 License Number NPF-3 Serial Number 3326 Page 2 of 2 Very truly yours,
- 2tU56 Mark B. Bezilla, Vice Prefdent-Nuclear
Enclosure:
FirstEnergy Nuclear Operating Company Davis-Besse Nuclear Power Station Request to Use Subsequent ASME Code Edition and Addenda in Accordance with 10 CFR 50.55a(g)(4)(iv).
Attachment:
Commitment List cc: Regional Administrator, NRC Region III NRC/NRR Project Manager NRC Senior Resident Inspector Utility Radiological Safety Board C. O'Claire, Ohio Emergency Management Agency
Docket Number 50-346 License Number NPF-3 Serial Number 3326 Attachment Page 1 of 1 Commitment List The following list identifies those actions committed to by the FirstEnergy Nuclear Operating Company (FENOC) in this document. Any other actions discussed in the submittal represent intended or planned actions by FENOC. They are described only for information and are not regulatory commitments. Please contact Mr. Henry L. Hegrat, FENOC Fleet Licensing Supervisor (330-374-3114), with any questions regarding this document or associated regulatory commitments.
Docket Number 50-346 License Number NPF-3 Serial Number 3326 Enclosure Page 1 of 2 FirstEnergy Nuclear Operating Company Davis-Besse Nuclear Power Station Request to Use Subsequent ASME Code Edition and Addenda in Accordance with 10 CFR 50.55a(g)(4)(iv)
- 1. ASME Code Component Affected Component Number: 1V2" Pressurizer Thermo Well Nozzle (MK 29)
Code Class: Class 1
- 2. Applicable Code Edition and Addenda ASME Section XI, 1995 Edition through the 1996 Addenda
- 3. Proposed Subseqluent Code Edition and Addenda IVA-4461 of ASME Section XI, 1998 Edition through the 2000 Addenda
- 4. Related Requirements FirstEnergy Nuclear Operating Company (FENOC) plans to perform preemptive repairs to the 1'-inch pressurizer thermo well nozzle using a half-nozzle repair method. The Electro Discharge Machining (EDM) technique is the selected process to remove the metal necessary for the repair. However, requirements for EDM are not addressed in American Society of Mechanical Engineers (ASME)Section XI, 1995 Edition through the 1996 Addenda, which is the code in effect for the Davis-Besse Nuclear Power Station (DBNPS). Therefore, FENOC intends to incorporate the requirements of ASME Section XI, 1998 Edition through the 2000 Addenda, Paragraph IWA-4461, which is approved for use in 10 CFR 50.55a without any limitations and identifies EDM as an acceptable process, for the metal removal process.
,WA-4461.3contains mechanical processing requirements for using EDM to remove P-No. 43 material, which is the material to be removed for the pressurizer thermo well nozzle repairs. However, IWA-4461.4 provides an acceptable alternative to the IWA-4461.3 requirements. FENOC intends to apply the IWA-4461.4 requirements, which are as follows:
IWA-4461.4 Alternative to Mechanical Processing. Mechanical processing of thermally cut surfaces for materials identified in IWA-4461.2 and IWA-4461.3 is not required when using a thermal metal removal process qualified as follows:
(a) The qualification test shall consist of two coupons of the same P-No.
material to be cut in production.
Docket Number 50-346 License Number NPF-3 Serial Number 3326 Enclosure Page 2 of 2 (b) The qualification coupons shall be cut using the maximum heat input to be used in production.
(c) The thermally cut surface of each coupon shall be visually examined at lOX and shall be free of cracks. The Owner shall specify surface roughness acceptable for the application and shall verify that the qualification coupon meets the criterion.
(d) Each qualification coupon shall be cross sectioned, and the exposed surfaces shall be polished, etched with a suitable etchant, and visually examined at lOX. All sectioned surfaces shall be free of cracks.
(e) Corrosion testing of the thermally cut surfaces and heat affected zone shall be performed if the cut surface is to be exposed to corrosive media. Alternatively, corrosion resistance of the thermally cut surface may be evaluated. The Owner shall specify the acceptance criteria.
FENOC intends to perform all other activities associated with the repair of the thermo well nozzle in accordance with IWA-4000 of ASME Section XI, 1995 Edition through the 1996 Addenda.
- 5. Duration of Proposed Request This request will remain in effect for the duration of repairs to the I 'A-inch pressurizer thermo well nozzle planned for the next maintenance and refueling outage, which is currently scheduled to commence in December 2007.
