DPR-23 SUPPLEMENTAL RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION RELATED TO RELIEF REQUEST (RR)-07 FROM IMMEDIATE ASME CODE REPAIR OF REFUELING 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, Carolina Power and Light Company, now doing business as Progress Energy, submitted a response to a request for additional information (RAI) received from NRC staff on October 16, 2012 (Agencywide Documents Access and Management System Accession No. ML12290A251) 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, of the ASME Section XI Code requireier'lt as stipulated in Paragraph IWC-3122.2 on the basis that compliance with the specified requirements would result in a hardship or unusual difficulty without a compensating increase in the level of quality and safety. RR-07 was submitted after discovery 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 Energy provided the requested information for RAI items 1(1), 2, and 3(3). In its responses to RAI items 1(2), 3(1), and 3(2) Progress Energy indicated that the requested information would be provided in a separate supplemental response pending finalization of the design of the clamp or completion of a calculation of the maximum leakage flaw size that does not challenge the RWST inventory make-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.

By letter dated October 5, 2012, (Agencywide Documents Access and Management System Accession No. ML12292A386) Carolina Power and Light (the licensee) requested relief from the requirements of the 2007 Edition through the 2008 Addenda of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, IWC-3122.2. The licensee proposed an alternative to repair a degraded drain valve that is connected to the Refueling Water Storage Tank (RWST) as discussed in Relief Request Number RR-07. To complete its review, the Nuclear Regulatory Commission (NRC) staff requests the following information:
- 1. Page 2 of the relief request states that the current leak rate does not challenge the RWST inventory make-up capabilities. (1) Provide the actual RWST inventory make-up capabilities (e.g., in gallons per minute) and discuss the source and delivery of the make-up coolant. (2) Provide the maximum leakage flaw size (approximation is acceptable) that would not challenge the make-up capabilities.
- 2. Page 4 of the relief request discusses the allowable through wall axial and circumferential flaw length. Submit the fracture mechanics calculation of the allowable flaw lengths.
- 3. (1) Provide the design drawing(s) and the stress analysis of the mechanical clamp. 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, and allowable stresses. Discuss if the stress analysis indicates the mechanical clamp will 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 the acceptability of the weekly monitoring frequency and provide leak rate limits at which time corrective action would be taken. When establishing the leak rate limits, please discuss how these limits will ensure that adequate capacity will be maintained in the tank to ensure the design basis is maintained.
United States Nuclear Regulatory Commission Enclosure to Serial: RNP-RA!12-0119 Page 2 of 3 DISCUSSION Progress Energy provided a response to the above requested information by letter dated October 25, 2012 which provided the requested information for items 1(1), 2, and 3(3). The response to items 1(2), 3(1), and 3(2) indicated that a separate supplemental response would be submitted to provide requested information that was not available due to the pending completion of a calculation of the maximum leakage flaw size that does not challenge the RWST inventory make-up capability, item 1(2) and finalization of the clamp design, items 3(1) and 3(2). The requested 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 challenge the nominal RWST inventory make-up capability of 84 gallons per minute to be no less than 2.5 inches long with a width 0.377 inches and no less than 12.9 inches long with a width of 0.073 inches.
Supplemental Response - RAI Item 3(1)
Design drawings of the leak limiting mechanical clamping device Progress Energy plans to install are presented on pages 1 and 2 of the Attachment. The leak limiting mechanical clamping device is not designed to exert forces on the flaw in the valve body sufficient to mitigate its growth and/or reduce leakage through the valve body.
The mechanical clamp consists of a Furmanite box that is to be installed to enclose the entire valve. The Furmanite box is designed to provide a pressure boundary that prevents discharge from the leak through the valve body to the environment under expected pressures and temperatures. A copy of the stress analysis for the Furmanite box is presented on pages 3 through 7 of the Attachment.
The Furmanite box is designed such that all calculated stresses are less than allowable stresses for 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 between the outside diameter of the drain line and the inside diameter of the box to form an o-ring type seal. Sealant is applied both upstream and downstream of the valve. Sealant is also injected at the interface between the clamping surfaces of the Furmanite box to seal the box. The amount of Furmanite material injected will be monitored and controlled to prevent introduction of sealant material into the piping and/or valve.
United States Nuclear Regulatory Commission Enclosure to Serial: RNP-RA/12-0119 Page 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 is included in the weight of the clamping device used in assessing the capability to meet applicable structural requirements.
