PARTICIPATION IN A VOLUNTARY TELECONFERENCE TO DISCUSS THE
. RESULTS OF STEAM GENERATOR TUBE EXAMINATIONS i
Dear Mr. Nocci:
As a means to keep informed of issues that may require NRC technical staff involvement, the staff of the NRC's Material and Chemical Engineering Branch has requested your participation i
in a voluntary teleconference to discuss the results of your examination of the steam generator tubes at Millstone Unit No. 3 planned for the upcoming refueling outage. As discussed with members of your staff, this teleconference would be best scheduled when you have the results from between one-half and three-quarters of the planned examinations. Your participation in this teleconference would enhance the capability of the NRC's technical staff in resolving issues you may identify during this refueling outage related to steam generator tube integrity.
i The enclosure provides the tcpics that the technical staff would like to discuss during the
]
teleconference provided you are able to support one. To arrange the teleconference or if you have questions or comments, please contact me at (301) 415-1278.
Sincerely, l

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 discussion. Typical areas of discussion include:
o Primary to secondary leakage prior to shutdown e Results of secondary side hydro For each steam generator, a general description of areas examined; including expansion 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 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
experiences Discussion of new inspection findings, including loose parts indications e
Description of in-situ pressure test plans and results; include tube selection criteria, test e
pressure plans, test configuration e Describe tube pull plans and preliminary results; include tube selection criteria and evaluation plans Assessment of tube integrity for previous operating cycle e
e Assessment of tube integrity for next operating cycle Provide schedule for steam generator-related activities during remainder of currcnt outage o
Note:
it may facilitate the discussion if the licensee provides details on the topics listed above prior to the conference call (e.g., simple tables and figures).
