REQUEST FOR ADDITIONAL INFORMATION DRESDEN NUCLEAR POWER STATION, UNIT 3 DOCKET NO. 50-249 In reviewing the Exelon Generation Companys (Exelons) submittal dated May 8, 2005, related to the request for relief from American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components, and the augmented examinations specified in 10 CFR 50.55a(g)(6)(ii)(A)(2), for the Dresden Nuclear Power Station, Unit 3 (Dresden 3), the NRC staff has determined that the following information is needed in order to complete its review:
By letter dated March 23, 2005, the NRC approved an alternative Reactor Pressure Vessel (RPV) weld examination pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Section 50.55a(a)(3)(I) and 10 CFR 50.55a(g)(6)(ii)(A)(5) for Dresden Nuclear Power Station, Units 2 and 3 (Dresden 2 and 3) that allows permanent deferral of the requirements to perform a volumetric examination of the RPV circumferential welds for the extended operating license terms for Dresden 2 and 3. This alternative requires examinations of essentially 100 percent of all longitudinal welds and examinations of approximately 2 to 3 percent of the circumferential welds at their points of intersection with the longitudinal welds.
In proposed Relief Request CR-28, Exelon did not indicate the extent to which the reduced examination volumes for the RPV longitudinal welds, as specified in the attachment to their May 6, 2005, letter, included the points of intersection with the circumferential welds. Please provide supplemental information indicating whether the reduced examination volumes for the specified Dresden 3 RPV longitudinal welds included all of the points of intersection with the circumferential welds. In addition, please indicate whether 2 to 3 percent volumetric coverage of the circumferential welds in the vicinity of the points of intersection with the longitudinal welds was achieved.
