Request for Additional Information - Duane Arnold Energy Center (DAEC) - Fifth Ten Year Service Inspection Interval - Relief Request No. RR-04, Rev. 0 - Proposed Alternative for Seal Weld Procedure Qualification - MF9373 By letter dated March 7, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17069A172), NextEra Energy Duane Arnold, LLC (the licensee), requested the U.S. Nuclear Regulatory Commission (NRC) to authorize an alternative to the requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) IWA-4221 to allow weld procedure specifications (WPSs) for seal welding of installed and spare Main Steam Relief Valves (MSRVs) to be post-production qualified at Duane Arnold Energy Center (DAEC) for the fifth 10-year inservice inspection interval (ISI). The current request is identified as Relief Request Number RR-04, Revision 0.

By letter dated July 31, 2007 (ADAMS Accession No. ML072220137) the licensee submitted Relief Request Number NDE-R012, as an alternative to ASME Code regarding post-production of WPSs for seal welding of installed and spare MSRVs. The licensee provided supplemental information in a letter dated February 19, 2008 (ADAMS Accession No. ML080590357). The NRC issued the safety evaluation for the fourth 10-year ISI interval Relief Request Number NDE-R012 on July 2, 2008 (ADAMS No. ML081680709). The NRC staff notes that the fourth 10-year ISI Relief Request Number NDE-R012 and the current fifth 10-year ISI Relief Request Number RR-0 4, appear to be identical except for the interval identified and Code Edition and Addenda, Verify that the supplemental information provided in the February 19, 2008 letter, referenced above, is applicable to the current requested alternative.

Please arrange a teleconference with the NRC staff to discuss the subject information. Thanks Mahesh Chawla Project Manager Phone: 301-415-8371 Fax: 301-415-1222 mahesh.chawla@nrc.gov 1
