| By letter dated September 30, 2008, as supplemented by letter dated January 23, 2009, FPL Energy Duane Arnold, LLC, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 (10 CFR Part 54) for renewal of Operating License No. DPR-49 for the Duane Arnold Energy Center (DAEC). The staff of the U.S. Nuclear Regulatory Commission (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 identifies areas where additional information is needed to complete the review. The staff held a conference call with Ken Putnam of your staff on August 12, 2010, to inform him of a late-breaking request for additional information (RAI) regarding the aging management of in-scope inaccessible low voltage cable at DAEC. Enclosed is the RAI associated with that discussion. | | By letter dated September 30, 2008, as supplemented by letter dated January 23, 2009, FPL Energy Duane Arnold, LLC, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 (10 CFR Part 54) for renewal of Operating License No. DPR-49 for the Duane Arnold Energy Center (DAEC).

| As stated cc w/encl: Distribution via Listserv DUANE ARNOLD ENERGY LICENSE RENEWAL REQUEST FOR ADDITIONAL RAI B 3.27-7 Background NUREG-1801, Rev. 1, "Generic Aging Lessons Learned," (the GALL Report) addresses inaccessible medium voltage cables in Aging Management Program (AMP) XI,E3, "Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements." The purpose of this program is to provide reasonable assurance that the intended functions of inaccessible medium voltage cables (2 kV to 35 kV), that are not subject to environmental qualification requirements of 10 CFR 50.49 and are exposed to adverse localized environments caused by moisture while energized, will be maintained consistent with the current licensing basis. The scope of the program applies to inaccessible (in conduits, cable trenches, cable troughs, duct banks, underground vaults or direct buried installations) voltage cables within the scope of license renewal that are subject to significant moisture simultaneously with significant voltage. The application of AMP XI,E3 to medium voltage cables was based on the operating experience (OE) available at the time Revision 1 of the GALL Report was developed. | | As stated cc w/encl: Distribution via Listserv |
| However, recently identified industry OE indicates that the presence of water or moisture can be a contributing factor in inaccessible power cables failures at lower service voltages (480 V to 2 kV). Applicable OE was identified in licensee responses to Generic Letter 2007-01, "Inaccessible or Underground Power Cable Failures that Disable Accident Mitigation Systems or Cause Plant Transients," which included failures of power cable operating at service voltages of less than 2 kV where water was considered a contributing factor. The staff has proposed changes to be included in the next revision of the GALL Report AMP XI,E3 to address recently identified OE concerning the failure of inaccessible low voltage power cables, which includes general water intrusion as a failure mechanism and increases the scope of program to include power cables greater than or equal to 480 V. The staff has concluded, based on recently identified industry OE concerning the failure of inaccessible low voltage power cables (480 V to 2 kV) in the presence of significant moisture, that these cables should be included in an AMP. The staff notes that your AMP does not address these low voltage cables. Request Provide a summary of your evaluation of recently identified industry OE and any plant specific OE concerning inaccessible low voltage power cable failures within the scope of license renewal (not subject to 10 CFR 50.49 environmental qualification requirements), and how this OE applies to the need for additional aging management activities by the applicant for such cables. ENCLOSURE | | |

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 16, 2010 Mr. Christopher Costanzo Vice President, Nuclear Plant Support NextEra Energy Duane Arnold, LLC P.O. Box 14000 Juno Beach, FL 33408-0420
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE DUANE ARNOLD ENERGY CENTER LICENSE RENEWAL APPLICATION LOW VOLTAGE CABLES (TAC NO. MD9769)
Dear Mr. Costanzo:
By letter dated September 30, 2008, as supplemented by letter dated January 23, 2009, FPL Energy Duane Arnold, LLC, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 (10 CFR Part 54) for renewal of Operating License No. DPR-49 for the Duane Arnold Energy Center (DAEC). The staff of the U.S. Nuclear Regulatory Commission (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 identifies areas where additional information is needed to complete the review.
The staff held a conference call with Ken Putnam of your staff on August 12, 2010, to inform him of a late-breaking request for additional information (RAI) regarding the aging management of in-scope inaccessible low voltage cable at DAEC. Enclosed is the RAI associated with that discussion.
As stated during the conference call, the staff will strive to reach resolution on the low voltage cable issue and publish the final Safety Evaluation Report for DAEC no later than September 7, 2010. However, if we are unable to resolve the matter during the course of this review, you will be promptly notified of impacts to the review schedule.
C. Costanzo -2 If you have any questions, please contact me by telephone at 301-415-2277 or bye-mail at Brian. Harris2@nrc.gov.
Sincerely,
- f? ~r Briari K. Harris, Project Manager Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket No. 50-331

DUANE ARNOLD ENERGY CENTER LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION RAI B 3.27-7
Background
NUREG-1801, Rev. 1, "Generic Aging Lessons Learned," (the GALL Report) addresses inaccessible medium voltage cables in Aging Management Program (AMP) XI,E3, "Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements." The purpose of this program is to provide reasonable assurance that the intended functions of inaccessible medium voltage cables (2 kV to 35 kV), that are not subject to environmental qualification requirements of 10 CFR 50.49 and are exposed to adverse localized environments caused by moisture while energized, will be maintained consistent with the current licensing basis. The scope of the program applies to inaccessible (in conduits, cable trenches, cable troughs, duct banks, underground vaults or direct buried installations) medium voltage cables within the scope of license renewal that are subject to significant moisture simultaneously with significant voltage.
The application of AMP XI,E3 to medium voltage cables was based on the operating experience (OE) available at the time Revision 1 of the GALL Report was developed. However, recently identified industry OE indicates that the presence of water or moisture can be a contributing factor in inaccessible power cables failures at lower service voltages (480 V to 2 kV).
Applicable OE was identified in licensee responses to Generic Letter 2007-01, "Inaccessible or Underground Power Cable Failures that Disable Accident Mitigation Systems or Cause Plant Transients," which included failures of power cable operating at service voltages of less than 2 kV where water was considered a contributing factor. The staff has proposed changes to be included in the next revision of the GALL Report AMP XI,E3 to address recently identified OE concerning the failure of inaccessible low voltage power cables, which includes general water intrusion as a failure mechanism and increases the scope of program to include power cables greater than or equal to 480 V.
The staff has concluded, based on recently identified industry OE concerning the failure of inaccessible low voltage power cables (480 V to 2 kV) in the presence of significant moisture, that these cables should be included in an AMP. The staff notes that your AMP does not address these low voltage cables.
Request
- 1. Provide a summary of your evaluation of recently identified industry OE and any plant specific OE concerning inaccessible low voltage power cable failures within the scope of license renewal (not subject to 10 CFR 50.49 environmental qualification requirements), and how this OE applies to the need for additional aging management activities by the applicant for such cables.
ENCLOSURE
-2
- 2. Provide a discussion of how Duane Arnold Energy Center will manage the effects of aging on inaccessible low voltage power cables within the scope of license renewal and subject to aging management review; with consideration of recently identified industry DE and any plant-specific DE. The discussion should include assessment of your AMP description.
program elements (i.e .* Scope of Program. Parameters Monitoredllnspected. Detection of Aging Effects. and Corrective Actions). and Final Safety Analysis Report summary description to demonstrate reasonable assurance that the intended functions of inaccessible low voltage power cables subject to adverse localized environments will be maintained consistent with the current licensing basis through the period of extended operation.
C. Costanzo If you have any questions, please contact me by telephone at 301-415-2277 or bye-mail at Brian.Harris2@nrc.gov.
