Enclosure REQUEST FOR ADDITIONAL INFORMATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION REGARDING RELIEF REQUEST HC-RR-B12 HOPE CREEK GENERATING STATION DOCKET NUMBER 50-354 By letter dated April 14, 2003, PSEG Nuclear, LLC (the licensee), requested relief from the required volumetric examination required by the American Society of Mechanical Engineers Code,Section XI, Table IWB-2500-1, Examination Category B-D, Item B3.100. The relief was requested pursuant to Title 10 of the Code of Federal Regulations Section 50.55a(a)(3)(ii). The NRC staff is reviewing your submittal and has determined that the following information will be needed for the staff to complete its review.
- 1. Table 1 in the submittal includes the summary number and component identification for each nozzle to be examined. The type of nozzle to be examined is also important because nozzles subjected to large thermal gradients have a past history of thermal cracking.
Describe the type (i.e., feedwater, recirculation inlets, jet pump instrumentation, etc.),
nominal inside diameter and material (i.e., carbon, nickel, etc.) of the nozzles included in the relief request.
- 2. The licensee states the estimated coverage of each of the nozzles in Table 1 of its submittal. This list fails to state specific information about which area of the nozzle will be inaccessible to examination (e.g., top, side, bottom). The severity of thermal fatigue is dependant upon the circumferential location, thermal gradient and thermal sleeve leakage.
Describe the portion of each nozzle that will be inaccessible to examination, providing a sketch if necessary.
- 3. In the alternative, the licensee states that the resolution sensitivity will be established using a 1-mil diameter wire standard that is similar to that used for other reactor pressure vessel internal examinations intended to detect cracking, without stating which standards are being referenced. Explain the qualification process that will be used to demonstrate the 1-mil width sensitivity and the equipment used for the examination.
