| By letter dated August 27,2010, FirstEnergy Nuclear Operating Company submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 for renewal of Operating License NPF-3 for the Davis-Besse Nuclear Power Station. The staff of the U.S. Nuclear Regulatory Commission (NRC or the staff) is reviewing this application in accordance with the guidance in NUREG-1800, "Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants." During its review, the staff has identified areas where additional information is needed to complete the review. The staff's requests for additional information are included in the enclosure. Further requests for additional information may be issued in the future. Items in the enclosure were discussed with Cliff Custer, of your staff, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me by telephone at 301-415-2946 or bye-mail at Samuel. CuadradoDeJesus@nrc.gov. Sincerely, Office of Nuclear Reactor Regulation Docket No. 50-346 | | By letter dated August 27,2010, FirstEnergy Nuclear Operating Company submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 for renewal of Operating License NPF-3 for the Davis-Besse Nuclear Power Station.

| The November 2,2012, supplemental response to request for additional information (RAI) B.2.4-1 states that American Society of Testing and Materials (ASTM) A-540 bolts are used in structural applications. The response classified ASTM A-325 and A-490 structural bolts as high strength. However, depending on the grade and class of ASTM A-540 bolts, the minimum specified yield strength of the material is specified as 130,140, or 150 kilo-pounds per square inch (ksi). NUREG-1801, "Generic Aging Lessons Learned (GALL) Report," aging management program (AMP) XI.M18 states, "[p]reventive measures also include using bolting material that has an actual measured yield strength limited to less than 1,034 megapascals (MPa) (150 kilo-pounds per square inch [ksi])." Given the variability in actual yield strength supplied by a material manufacturer, it is possible that some in-service ASTM A-540 bolts should be classified as high strength. GALL Report AMP XI.M18 further states that, "[h]igh strength closure bolting (actual yield strength greater than or equal to 1,034 MPa [150 ksi]), if used, should be monitored for cracking." The original response to RAI B.2.4-1, provided on May 24, 2011, which stated, "[v]isual examinations of structural assemblies will detect corrosion or conditions indicative of a corrosive environment that could lead to stress corrosion cracking (SCC) in potentially susceptible high strength bolting, and will cause appropriate corrective action to be taken under the Corrective Action Program when necessary," is still applicable if there are high strength ASTM A-540 bolts. Issue: The staff lacks sufficient information to determine which ASTM A-540 grade and class materials were used; if grade and class materials were used that have a minimum specified yield equal to or higher than 130 ksi; the actual measured yield strength of inservice bolts; if none of the currently installed bolts are high strength bolts; what controls will be in place to ensure that the actual measured yield strengths of ASTM A-540 supplied replacements will not exceed 150 ksi; and what inspections will be conducted for these high strength bolts. In addition, if visual examinations will be used to detect corrosion or conditions indicative of a corrosive environment that could lead to SCC, it is unclear how a corrosive environment is defined at Davis-Besse Nuclear Power Station (Davis-Besse), and how a non-corrosive environment can be guaranteed to be maintained throughout the period of extended operation. | | |

Projects Branch 1 Division of License Renewal UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 November 14, 2012 Mr. Raymond A. Lieb, Vice President Davis-Besse Nuclear Power Station FirstEnergy Nuclear Operating Company 5501 North State Route 2 Oak Harbor, OH 43449 REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE DAVIS-BESSE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION RELATED TO HIGH STRENGTH BOLTING (TAC NO. ME4640)
Dear Mr. Lieb:
By letter dated August 27,2010, FirstEnergy Nuclear Operating Company submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 for renewal of Operating License NPF-3 for the Davis-Besse Nuclear Power Station. The staff of the U.S. Nuclear Regulatory Commission (NRC or the staff) is reviewing this application in accordance with the guidance in NUREG-1800, "Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants." During its review, the staff has identified areas where additional information is needed to complete the review. The staff's requests for additional information are included in the enclosure.
Further requests for additional information may be issued in the future. Items in the enclosure were discussed with Cliff Custer, of your staff, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me by telephone at 301-415-2946 or bye-mail at Samuel. CuadradoDeJesus@nrc.gov.
Sincerely, Office of Nuclear Reactor Regulation Docket No. 50-346
Enclosure:
Requests for additional information cc w/encl: Listserv DAVIS-BESSE NUCLEAR POWER LICENSE RENEWAL REQUEST FOR ADDITIONAL RELATED TO HIGH STRENGTH RAI B.2.4-1 a
Background:
The November 2,2012, supplemental response to request for additional information (RAI) B.2.4-1 states that American Society of Testing and Materials (ASTM) A-540 bolts are used in structural applications.
The response classified ASTM A-325 and A-490 structural bolts as high strength.
However, depending on the grade and class of ASTM A-540 bolts, the minimum specified yield strength of the material is specified as 130,140, or 150 kilo-pounds per square inch (ksi). NUREG-1801, "Generic Aging Lessons Learned (GALL) Report," aging management program (AMP) XI.M18 states, "[p]reventive measures also include using bolting material that has an actual measured yield strength limited to less than 1,034 megapascals (MPa) (150 kilo-pounds per square inch [ksi])." Given the variability in actual yield strength supplied by a material manufacturer, it is possible that some in-service ASTM A-540 bolts should be classified as high strength.
GALL Report AMP XI.M18 further states that, "[h]igh strength closure bolting (actual yield strength greater than or equal to 1,034 MPa [150 ksi]), if used, should be monitored for cracking." The original response to RAI B.2.4-1, provided on May 24, 2011, which stated, "[v]isual examinations of structural assemblies will detect corrosion or conditions indicative of a corrosive environment that could lead to stress corrosion cracking (SCC) in potentially susceptible high strength bolting, and will cause appropriate corrective action to be taken under the Corrective Action Program when necessary," is still applicable if there are high strength ASTM A-540 bolts. Issue: The staff lacks sufficient information to determine which ASTM A-540 grade and class materials were used; if grade and class materials were used that have a minimum specified yield equal to or higher than 130 ksi; the actual measured yield strength of inservice bolts; if none of the currently installed bolts are high strength bolts; what controls will be in place to ensure that the actual measured yield strengths of ASTM A-540 supplied replacements will not exceed 150 ksi; and what inspections will be conducted for these high strength bolts. In addition, if visual examinations will be used to detect corrosion or conditions indicative of a corrosive environment that could lead to SCC, it is unclear how a corrosive environment is defined at Davis-Besse Nuclear Power Station (Davis-Besse), and how a non-corrosive environment can be guaranteed to be maintained throughout the period of extended operation.
-2 Request: The staff requests the applicant state the following: The ASTM A-540 grade and class of materials that are used in in-scope structural locations If grade and class materials were used that have a minimum specified yield equal to or higher than 130 ksi, the actual measured yield strength of in-service bolts If none of the currently installed bolts are high strength bolts, what controls will be in place to ensure that the actual measured yield strengths of A-540 supplied replacements will not exceed 150 ksi If high strength ASTM A-540 bolting material has been used in in-scope structural applications, what inspections will be conducted If visual examinations will be used to detect corrosion or conditions indicative of a corrosive environment in lieu of volumetric or surface (for removed bolts) examinations to detect SCC, the definition for a corrosive environment at Davis-Besse, and the threshold for which an environment will be classified as corrosive How it will be demonstrated that a non-corrosive environment is maintained for all high strength bolts, and how visual inspections will be able to detect all instances of corrosion or a corrosive environment, or update the AMP to show that volumetric examinations comparable to that of American Society of Mechanical Engineers Code Section XI, Table IWB-2500-1, Examination Category BG-1 are being performed on high strength bolting November 14, 2012 Mr. Raymond A.
