i Ste6.m Generator Tube inspection Results Licensees' steam generator (SG) tube eddy current (EC) inspections play a vital role in the management of SG tube degradation. The results are used to demonstrate adequate structural and

, leakage integrity of the SG tubes.

1 NRC staff is interested in discussing the licensee's steam generator inspection plans and results, although the licensee is not required to participate in this discussion. The following list of topics i describes areas the NRC staff typically is interested in talking about, i

f Primary to secondary leakage prior to shutdown Results of secondary side hydro i For each steam generator, provide a general description of areas examined; include expansion i criteria and specify type of probe used in each area For analyzed EC results, describe bobbin indications (those not examined with RPC) and RPC/Plus Point /Cecco indications. Include the following information: location, number, degradation mode, disposition, and voltages / depths / lengths of most significant indications.

I Describe repair / plugging plans Discuss previous history: "look backs" performed Discuss new inspection findings

} Describe in-situ pressure test plans and results, if available; include tube selection criteria Describe tube pull plans and preliminary results, if available; include tube selection criteria 4

Assessment of tube integrity for previous operating cycle

. Assessment of tube integrity for next operating cycle Provide schedule for steam generator-related activities during remainder of current outage Note: You are encouraged to provide details on the topics listed above prior to the conference call (e.g., simple tables and figures) if you think it will facilitate the discussion.
