management of SG tube degradation. The results are used to demonstrate adequate structural and leakage integrity of the SG tubes.

L NRC staff is interested in discussing the SNC's steam generator inspection plans and results, although you are not required to participate in this discussion. Typical areas of discussion include:

i Primary to secondary leakage prior to shutdown e

Results of secondary side hydro

)

e l-For each steam generator, a general description of areas examined; including expansion i

e criteria and type of probe used in each area For analyzed EC results, a description of bobbin indications (those not examined with RPC e

l (Rotating Pancake Coil)) 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' e

l experiences Discussion of new inspection findings, including loose parts indications Description of in-situ pressure test plans and results; include tube selection criteria, test e

pressure plans, test configuration l

Describe tube pull plans and preliminary results; include tube selection criteria and evaluation e
