DRESDEN AND QUAD CITIES LICENSE RENEWAL APPLICATION SUPPLEMENTAL REQUEST FOR ADDITIONAL INFORMATION RAI B.1.8 According to BWRVIP-27, the P/SLC nozzles at D/QCNPS are made of low-alloy steel instead of Alloy 600 and are susceptible to cracking. BWRVIP-27 describes an inspection strategy for these nozzles that includes volumetric inspection of the nozzle-to-shell weld and the nozzle inner blend radius at each inspection interval. In addition, NUREG-1801, Chapter XI.M8 requires the P/SLC nozzles to be inspected in accordance with the requirements of ASME Section XI, Subsection IWB. In Appendix B.1.8 of the LRA, the applicant states that the Dresden and Quad Cities programs utilize relief request ISI CR-01 (relief granted per SER dated September 15, 1995) that provides for inspection of the inner blend radius by a VT-2 examination instead of the normal volumetric examination. Future relief requests may be submitted by the applicant in accordance with 10 CFR 50.55a. Otherwise, the applicant must comply with the appropriate requirements of the ASME Code. Please confirm that the aforementioned aging effects for the P/SLC nozzles at D/QCNPS will be inspected in accordance with the requirements of ASME Section XI, Subsection IWB for license renewal.
