SUBJECT:
SALEM NUCLEAR GENERATING STATION, UNIT NO. 2 - UPCOMING STEAM GENERATOR TUBE INSERVICE INSPECTION (TAC NO. MB4599)
Dear Mr. Keiser:
Inservice inspections of steam generator (SG) tubes play a vital role in ensuring that adequate structural integrity of the tubes is maintained. As required by the Salem Nuclear Generating Station (Salem), Unit No. 2, Technical Specifications (TSs), reporting requirements range from submitting a report within 15 days following completion of each inservice inspection of SG tubes that identifies the number of tubes plugged and/or repaired, to submitting a report included in your Annual Operating Report, within 12 months following completion of the inspection, that provides complete results of the SG tube inservice inspection. The report containing the complete results includes the following:
1.
Number and extent of tubes inspected; 2.
Location and percent of wall-thickness penetration for each indication of an imperfection; 3.
Identification of tubes plugged (and/or repaired).
A phone conference will be arranged in the near future with members of your staff to discuss the results of the SG tube inspections that will be performed during the upcoming Salem Unit 2 refueling outage. The conference call will be conducted at an appropriate time during the outage after a majority of the tubes have been inspected, but before the SG inspection activities have been completed. Enclosed is a list of discussion points to facilitate this phone conference.
H. Keiser We request that any significant results discussed during the phone conference, as well as any materials provided by your staff to assist us during the phone conference in the understanding of the SG tube results, be included in one of the special reports required by the TSs.
Sincerely,
/RA/

ENCLOSURE STEAM GENERATOR TUBE INSPECTION DISCUSSION POINTS PREPARED BY THE OFFICE OF NUCLEAR REACTOR REGULATION PSEG NUCLEAR LLC SALEM NUCLEAR GENERATING STATION, UNIT NO. 2 DOCKET NO. 50-311 The following discussion points have been prepared to facilitate the phone conference arranged with the Salem Nuclear Generating Station, Unit No. 2, (Salem) licensee to discuss the results of the steam generator (SG) tube inspections to be conducted during the upcoming Salem Unit 2 refueling outage. This phone call will be scheduled to occur towards the end of the planned SG tube inspection interval, but before the unit exits its refueling outage.
It is the staffs expectation that any significant results or relevant trends discussed during the phone conference, as well as any materials provided by your staff to assist us during the phone conference in the understanding of the SG tube results, will be included in one of the special reports required by the plant Technical Specifications.
1.
Discuss whether any primary to secondary leakage existed in this unit prior to shutdown.
2.
Discuss the results of secondary side hydrostatic tests.
3.
For each steam generator, provide a general description of areas examined, including the expansion criteria utilized and type of probe used in each area.
4.
For analyzed eddy current results, describe bobbin indications (those not examined with rotating pancake coil (RPC)) and RPC/Plus Point/Cecco/X-probe indications. Include the following information in the discussion: location, number, degradation mode, disposition, and voltages/depths/lengths of significant indications.
5.
Describe repair/plugging plans for the SG tubes that meet the repair/plugging criteria.
6.
Discuss the previous history of SG tube inspection results, including any "look backs" performed.
7.
Discuss, in general, the new inspection findings.
8.
Describe in-situ pressure test plans and results, if applicable and available, including tube selection criteria.
9.
Describe tube pull plans and preliminary results, if applicable and available; include tube selection criteria.
10.
Discuss the assessment of tube integrity for the previous operating cycle.
11.
Discuss the assessment of tube integrity for next operating cycle.
12.
Provide the schedule for steam generator-related activities during the remainder of the current outage.
13.
Discuss what steps have been taken, or will be taken, in response to the lessons learned from the Indian Point Unit 2 tube failure. In addition, please be prepared to discuss the following:
a) Discuss the actions that are taken in response to identifying a new degradation mechanism; b) Discuss the actions taken to ensure that data noise levels are acceptable, and; c) Address data quality issues and the need for criteria to address data quality.
