SUPPLEMENTAL RESPONSE TO REQUEST FOR ADDITIONAL INFORMATIONRELATED TO RELIEF REQUEST (RR)-07 FROM IMMEDIATE ASME CODE REPAIR OFREFUELING WATER STORAGE TANK DRAIN VALVE (SI-837)FOR FIFTH TEN-YEAR INSERVICE INSPECTION PROGRAM PLAN

By letter to the U. S. Nuclear Regulatory Commission (NRC), dated October 25, 2012, CarolinaPower and Light Company, now doing business as Progress Energy, submitted a response to arequest for additional information (RAI) received from NRC staff on October 16, 2012(Agencywide Documents Access and Management System Accession No. ML 12290A25 1)related to relief request (RR)-07 for the Fifth Ten-Year Inservice Inspection Program Plan for H.B, Robinson Steam Electric Plant (HBRSEP) Unit No. 2,

RR-07 was submitted to the NRC by letter dated October 5, 2012 (ADAMS Accession No.ML12292A386). RR-07 requested relief from the 2007 Edition, through the 2008 Addenda, ofthe ASME Section XI Code requireier'lt as stipulated in Paragraph IWC-3122.2 on the basis thatcompliance with the specified requirements would result in a hardship or unusual difficultywithout a compensating increase in the level of quality and safety. RR-07 was submitted afterdiscovery of a through-wall flaw in the body of the Refueling Water Storage Tank (RWST) drain

* valve (SI-837).

In its October 25, 2012 response to the request for additional information, Progress Energyprovided the requested information for RAI items 1(1), 2, and 3(3). In its responses to RAI items1(2), 3(1), and 3(2) Progress Energy indicated that the requested information would be providedin a separate supplemental response pending finalization of the design of the clamp or completionof a calculation of the maximum leakage flaw size that does not challenge the RWST inventorymake-up capability.

Enclosed, please find a supplementalresponse for items 1(2), 3(1), and 3(2) of the request for.additional information received by Progress Energy on October 16.

This letter contains no new Regulatory Commitments.

SUPPLEMENTAL RESPONSE TO REQUEST FOR ADDITIONALINFORMATION RELIEF REQUEST NUMBER RR-07

REPAIR OF SAFETY INJECTION VALVE SI-837H.B. ROBINSON STEAM ELECTRIC PLANT UNIT NO. 2

NRC REQUEST FOR ADDITIONAL INFORMATION (RAI)

By letter dated October 5, 2012, (Agencywide Documents Access and ManagementSystem Accession No. ML12292A386) Carolina Power and Light (the licensee)requested relief from the requirements of the 2007 Edition through the 2008 Addenda ofthe American Society of Mechanical Engineers (ASME) Boiler and Pressure VesselCode, Section XI, IWC-3122.2. The licensee proposed an alternative to repair adegraded drain valve that is connected to the Refueling Water Storage Tank (RWST) asdiscussed in Relief Request Number RR-07. To complete its review, the NuclearRegulatory Commission (NRC) staff requests the following information:

1. Page 2 of the relief request states that the current leak rate does not challengethe RWST inventory make-up capabilities. (1) Provide the actual RWSTinventory make-up capabilities (e.g., in gallons per minute) and discuss thesource and delivery of the make-up coolant. (2) Provide the maximum leakageflaw size (approximation is acceptable) that would not challenge the make-upcapabilities.

2. Page 4 of the relief request discusses the allowable through wall axial andcircumferential flaw length. Submit the fracture mechanics calculation of theallowable flaw lengths.

3. (1) Provide the design drawing(s) and the stress analysis of the mechanicalclamp. The design drawing(s) should show the dimensions (including weight)and how the clamp is installed on the valve (the final installed configuration).Along with the stress analysis, provide the methodology, assumptions, andallowable stresses. Discuss if the stress analysis indicates the mechanical clampwill exert sufficient forces on the flaw to mitigate its growth and reduce leakage.(2) Discuss if sealant is or is not used with the mechanical clamp to stop the leak.(3) If after installation of the clamp assembly, the leak continues, discuss theacceptability of the weekly monitoring frequency and provide leak rate limits atwhich time corrective action would be taken. When establishing the leak ratelimits, please discuss how these limits will ensure that adequate capacity will bemaintained in the tank to ensure the design basis is maintained.

DISCUSSION

Progress Energy provided a response to the above requested information by letter datedOctober 25, 2012 which provided the requested information for items 1(1), 2, and 3(3). Theresponse to items 1(2), 3(1), and 3(2) indicated that a separate supplemental response would besubmitted to provide requested information that was not available due to the pending completionof a calculation of the maximum leakage flaw size that does not challenge the RWST inventorymake-up capability, item 1(2) and finalization of the clamp design, items 3(1) and 3(2). Therequested information for RAI items 1(2), 3(1) and 3(2) are presented below.

Supplemental Response - RAI Item 1(2)

Progress Energy has calculated approximate maximum leakage flaw sizes that do not challengethe nominal RWST inventory make-up capability of 84 gallons per minute to be no less than2.5 inches long with a width 0.377 inches and no less than 12.9 inches long with a width of0.073 inches.

Supplemental Response - RAI Item 3(1)

Design drawings of the leak limiting mechanical clamping device Progress Energy plans toinstall are presented on pages 1 and 2 of the Attachment. The leak limiting mechanical clampingdevice is not designed to exert forces on the flaw in the valve body sufficient to mitigate itsgrowth and/or reduce leakage through the valve body.

The mechanical clamp consists of a Furmanite box that is to be installed to enclose the entirevalve. The Furmanite box is designed to provide a pressure boundary that prevents dischargefrom the leak through the valve body to the environment under expected pressures andtemperatures. A copy of the stress analysis for the Furmanite box is presented on pages 3through 7 of the Attachment.

The Furmanite box is designed such that all calculated stresses are less than allowable stressesfor each material and that the materials are suitable for the intended use.

Supplemental Response - RAI Item 3(2)

Sealant will not be used to seal the leak through the body of the RWST drain valve (SI-837).

The clamping device is a Furmanite injection box with sealant injected at the interface betweenthe outside diameter of the drain line and the inside diameter of the box to form an o-ring typeseal. Sealant is applied both upstream and downstream of the valve. Sealant is also injected atthe interface between the clamping surfaces of the Furmanite box to seal the box. The amount ofFurmanite material injected will be monitored and controlled to prevent introduction of sealantmaterial into the piping and/or valve.

United States Nuclear Regulatory CommissionEnclosure to Serial: RNP-RA/12-0119Page 3 of 3

The installed clamping device (the Furmanite box) will provide a pressure boundary that

encloses the valve and will prevent leakage to the environment. Leakage through the valve body

may occur after installation of the clamping device (Furmanite box) into the free volume

between the valve body and inside surface of the Furmanite box. The weight of such leakage isincluded in the weight of the clamping device used in assessing the capability to meet applicable

structural requirements.
