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 describes areas the NRC staff typically is interested in talking about, i
i Primary to secondary leakage prior to shutdown f
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.
