fy Steam 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. .

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 discenion. The following list

. of topics describes areas the NRC staff is interested in discussing:

o Primary to secondary leakage prior to shutdown e Results of secondary side hydro i l

e For each steam generator, a general description of areas examined; including I expansion criteria and type of probe used in each area l i

e- For analyzed EC results, a description of bobbin indications (those not examined with RPC) and RPC/Plus Point /Cecco indications.- Including the following information:

location, number, degradation mode, disposition, and voltages / depths / lengths of most significant indications e Description of repair / plugging plans

• Discussion of previous history; "look backs" performed; consideration of similar plants' experiences e Discussion of new inspection findings, including loose arts indications e Description of in-situ pressure test plans and results; include tube selection criteria, test pressure plans, test configuration e Describe tube pull plans and preliminary results; include tube selection criteria and evaluation plans e Assessment of tube integrity for previous operating cycle e . Assessment of tube integrity for next operating cycle
