REQUEST FOR ADDITIONAL INFORMATION DUKE POWER COMPANY CATAWBA NUCLEAR STATION, UNIT 2 DOCKET NO. 50-414 The Nuclear Regulatory Commission (NRC) staff has reviewed the licensees response dated February 10, 2004, to a request for additional information regarding the End of Core 12 steam generator tube inservice inspection for Catawba Nuclear Station, Unit 2. The NRC staff has identified the following information that is needed to enable the continuation of its review.
In your response to question 3, you indicate that you preventatively plugged two tubes (2A-1-100 and 2A-1-106) with anomalous U-bend volumetric indications. You also stated that you believe that the indications are an artifact of the plus point inspection.
A. During previous inspections, did you perform any rotating probe examinations in the U-bend area of these tubes? If so, discuss whether these anomalous indications were detected. Furthermore, if they were detected in previous inspections, discuss whether the indications changed from one inspection to the next and describe the implications of the changes.
B. If you performed rotating probe examinations in these tubes in the U-bend area during previous inspections and you did not detect anomalous indications, please provide insights on what caused the current anomalous indications.
C. Discuss your attempts to size the anomalous indications using any variety of non-destructive examination techniques so that you could confirm that the indications did not pose a structural or leakage integrity concern. Also, provide a justification for your conclusions that these indications are an artifact of the plus point inspection.
