Enclosure REQUEST FOR ADDITIONAL INFORMATION REGARDING STEAM GENERATOR TUBE EXAMINATIONS ENTERGY NUCLEAR OPERATIONS, INC.
INDIAN POINT NUCLEAR GENERATING UNIT NO. 2 DOCKET NO. 50-247 On June 14, 2006, Angencywide Documents Access and Management System accession number ML061780303, Entergy Nuclear Operations, Inc. (Entergy), submitted the results of the Indian Point Nuclear Generating Unit 2 steam generator tube examinations conducted during the spring 2006 refueling outage, as required by Technical Specification 5.5.7.f.2. The Nuclear Regulatory Commission staff is reviewing the submittal and has the following questions:
1.
Section 2.a.7 of your report dated June 14, 2006, indicated that the inspection program for refueling outage (RFO) 17 consisted of special interest examinations of abnormal indications. Please discuss the results of any special interest examinations on these indications. In addition, discuss what constitutes an abnormal indication.
2.
Section 2.b, Secondary Side Examinations, states that the top support plate in steam generators (SGs) 23 and 24 were visually inspected. Please discuss the results of these visual inspections. If any degradation was found, please discuss the basis for the inspection scope.
3.
It is stated in Section 3.0 that the largest bobbin indication (28-percent) located at an anti-vibration bar (AVB) was confirmed to be single-sided wear by +PointTM examination.
Please discuss whether all AVB wear scars were inspected with a rotating probe to confirm that they were also single-sided wear. If any of these indications were not single-sided wear (e.g., row 36 column 44 in SG 22), please discuss the method used to size these indications. If a qualified sizing technique does not exist for wear indications that are not single-sided, please discuss your basis for leaving them in service (if any were left in service).
4.
Please discuss whether the low levels of primary-to-secondary leakage observed during prior cycles is still present.
5.
For the tubes identified with permeability variations, discuss whether these locations were inspected with a rotating probe (e.g., magnetically biased +PointTM probe) to confirm the absence of degradation at these locations. Please discuss whether the size of these permeability variations limit the ability to reliably inspect these locations. If so, discuss your long-term strategy for addressing these indications.
6.
In your February 13, 2006 (ML060530378), letter you indicated that you would be performing primary side visual inspections and that you would be inspecting the top of the flow distribution baffle in all 4 SGs. Please discuss the results of these inspections.
