INDIAN POINT NUCLEAR GENERATING, UNIT NO. 3 REQUEST FOR ADDITIONAL INFORMATION REGARDING THE STEAM GENERATOR TUBE INSERVICE INSPECTIONS FOR THE SPRING 2013 REFUELING OUTAGE DOCKET NO. 50-286 By letter dated August, 15, 2013, (Agencywide Documents Access and Management Systems Accession Number [ADAMS] ML13235A047), Entergy Nuclear Operations, Inc., the licensee, submitted information summarizing the results of the 2013 steam generator (SG) tube inspections performed at Indian Point, Unit 3. The staff requests the following information:

1. The SG tube inspection report states that "no tubes were found with newly-formed degradation." It further states that there are eight small volumetric indications in the steam generator. If these eight tubes were inspected during the 3R 17 outage, please provide the size, location, orientation, and measured sizes of any service induced indications (regardless of whether they are new) including the eight small volumetric indications created in 2001 as a result of sludge lance rail wear.
2. Please clarify the results of the tube plug and primary bowl drain area inspections. For example, were all plugs present and in the correct position? Did any plugs show any evidence of leakage or degradation? For the primary bowl drain area inspections, were any anomalies or degradation detected?
3. Please clarify the results of the secondary side steam drum and top tube support plate inspections. For example, discuss deposit loading in the secondary side and discuss whether any anomalies or degradation were observed. The staff notes that in a prior inspection possible erosion/corrosion in two J-tube welds was identified. Please discuss whether these indications still exist or whether any other evidence exists that erosion/corrosion is occurring. If it is occurring, discuss the results of the condition monitoring and any planned corrective action.
4. Please discuss the results of the anti-vibration bar position verification.
