Fermi 2 - Request for Additional Information (ESGB & AFPB) - License Amendment Request Regarding 1.64% Measurement Uncertainty Recapture Power Uprate (TAC No. MF0650)

Attachments: Fermi 2 - Request for Additional Information (ESGB & AFPB) Regarding MUR LAR (TAC No MF0650).docx Mr. Hassoun:

By letter to the U.S. Nuclear Regulatory Commission (NRC) dated February 7, 2013 (Agencywide Documents Access and Management System Accession No. ML13043A659), Detroit Edison Company submitted a license amendment request application to increase the licensed core thermal power level at the Fermi Unit 2 from 3430 MWt to 3486 MWt. The approved license amendment would revise the Operating License and Technical Specifications to support operation at the increased licensed core thermal power.

The NRC staff in the Steam Generator Tube Integrity and Chemical Engineering Branch (ESGB) and Fire Protection Branch (AFPB) of the Office of Nuclear Reactor Regulation is currently reviewing your submittal. The staff has determined that additional information is required to continue its review and complete its technical evaluation. The request for additional information is attached.

Please provide your response by June 7, 2013.

You may request to discuss the contents of this RAI with the NRC staff in a conference call, including any change to the proposed schedule.

Please dont hesitate to contact either Mac Chawla or me if you have any questions or concerns.

Sincerely, Terry A. Beltz, Senior Project Manager Plant Licensing Branch III-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation (301) 415-3049 Terry.Beltz@nrc.gov 1

REQUEST FOR ADDITIONAL INFORMATION STEAM GENERATOR TUBE INTEGRITY AND CHEMICAL ENGINEERING BRANCH (ESGB)

AND FIRE PROTECTION BRANCH (AFPB)

OF THE OFFICE OF NUCLEAR REACTOR REGULATION REGARDING A LICENSE AMENDMENT REQUEST FOR FERMI UNIT 2 TO SUPPORT A 1.64% MEASUREMENT UNCERTAINTY RECAPTURE POWER UPRATE DETROIT EDISON COMPANY DOCKET NO. 50-341 (TAC NO. MF0650)

MUR-RAI-ESGB-1 Please provide the expected post design basis accident environmental conditions in containment with respect to the containment temperature, pressure, and radiological dose that the Service Level I coatings will be exposed to.

Additionally, please provide the radiological dose qualification of the Service Level I coatings used within containment.

MUR-RAI-AFPB-1 The NRC staff notes that Enclosure 7 to NRC-13004, General Electric Company (GE)-Hitachi Safety Analysis Report for Fermi 2, Thermal Power Optimization, NEDC-33578P, Revision 0, dated January 2013, Section 6.7, Fire Protection, states that There is no change in the physical plant configuration and the potential for minor changes to combustible loading as result of TPO uprate Please summarize any changes to the combustible loading, however minor, and discuss the impact of these changes on the plants compliance with the fire protection program licensing basis, 10 CFR 50.48, or applicable portions of 10 CFR 50, Appendix R.

MUR-RAI-AFPB-2 The NRC staff notes that Enclosure 7 to NRC-13004, General Electric Company (GE)-Hitachi Safety Analysis Report for Fermi 2, Thermal Power Optimization, NEDC-33578P, Revision 0, dated January 2013, Section 6.7, Fire Protection, states that The TPO uprate will have no effect on fire protection administrative controls, fire barriers, fire protection responsibilities of plant personnel and resources necessary for systems required to achieve and maintain safe-

shutdown However this section does not discuss the possibility of any change in plant procedures necessary for systems required to achieve and maintain safe-shutdown.

Please verify that any procedures associated with those systems required to achieve and maintain safe-shutdown will not change and remain adequate for the MUR power uprate.

MUR-RAI-AFPB-3 Some plants credit aspects of their fire protection system for other than fire protection activities (e.g., utilizing the fire water pumps and water supply as backup cooling or inventory for non-primary reactor systems).

If Fermi 2 credits its fire protection system in this way, the LAR should identify the specific situations and discuss to what extent, if any, the MUR power uprate affects these non-fire-protection aspects of the plant fire protection system.

If Fermi 2 does not take such credit, then please verify this as well.

In your response, please discuss if and, if so, how, any non-fire suppression use of fire protection water will impact the ability to meet the fire protection system design demands.
