UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 March 10, 2011 Mr. Paul Freeman Site Vice President clo Michael O'Keefe Seabrook Station NextEra Energy Seabrook, LLC P.O. Box 300 New Hampshire, NH 03874
SUBJECT:
SEABROOK STATION, UNIT NO.1 - UPCOMING STEAM GENERATOR TUBE INSERVICE INSPECTION (TAC NO. ME5715)
Dear Mr. Freeman:
Inservice inspections of steam generator (SG) tubes playa vital role in assuring SG tube integrity. Based on my discussion with Mr. Gary Kilby on February 17, 2011, a telephone conference call has been tentatively arranged for April 15, 2011, with members of your staff to discuss the ongoing results of the SG tube inspections to be conducted during the upcoming refueling outage for Seabrook Station, Unit No.1. This call will occur after the 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 call.
The Nuclear Regulatory Commission (NRC) staff will document a summary of the conference call, including any material that you provide to the NRC staff in support of the call.
Should you have any questions, please contact me at (301) 415-1420.

STEAM GENERATOR TUBE INSPECTION DISCUSSION POINTS The following discussion points have been prepared to facilitate the conference call arranged with the licensee to discuss the results of the steam generator (SG) tube inspections to be conducted during the upcoming spring 2011 refueling outage at Seabrook Station, Unit No. 1 (Seabrook). This conference call is scheduled to occur towards the end of the planned SG tube inspections, but before the inspections and repairs are completed. The NRC staff notes that the spring 2011 inspection is limited to 3 inches from the top of the tubesheet and is being performed in response to a single indication of outside diameter stress corrosion cracking identified in this area during the last inspection.
The NRC staff plans to document a summary of the conference call as well as any material that is provided in support of the call.
- 1. By letter dated January 27, 2011, NextEra Energy Seabrook, LLC submitted license amendment request (LAR) 10-06 for Seabrook (Agencywide Documents Access and Management System Accession No. ML110330202). LAR 10-06 requests a one-time implementation of alternate repair criteria for the SGs. As described in the LAR, the amendment is only needed if primary water stress-corrosion cracking is identified during the limited inspection of the SGs. Depending upon the need for the amendment, a discussion of inspection results to support the LAR would be expected.
- 2. Discuss any trends in the amount of primary-to-secondary leakage observed during the recently completed cycle.
- 3. Discuss whether any secondary side pressure tests were performed during the outage and the associated results.
- 4. Discuss any exceptions taken to the industry guidelines.
- 5. For each SG, provide a description of the inspections performed including the areas examined and the probes used (e.g., dents/dings, sleeves, expansion-transition, U-bends with a rotating probe), the scope of the inspection (e.g., 100 percent of dents/dings greater than 5 volts and a 20% sample between 2 and 5 volts), and the expansion criteria.
- 6. For each area examined (e.g., tube supports, dent/dings, sleeves, etc.), provide a summary of the number of indications identified to date for each degradation mode (e.g., number of circumferential primary water stress-corrosion cracking (PWSCC) indications at the expansion transition). For the most significant indications in each area, provide an estimate of the severity of the indication (e.g., provide the voltage, depth, and length of the indication). In particular, address whether tube integrity (structural and accident-induced leakage integrity) was maintained during the previous operating cycle.
In addition, discuss whether any location exhibited a degradation mode that had not previously been observed at this location at this unit (e.g., observed circumferential PWSCC at the expansion transition for the first time at this unit).
- 7. Describe repair/plugging plans.
Enclosure
- 2
- 8. Describe in-situ pressure test and tube pull plans and results (as applicable and if available).
- 9. Discuss the following regarding loose parts:
- what inspections are performed to detect loose parts;
- a description of any loose parts detected and their location within the SG (including the source or nature of the loose part, if known);
- if the loose parts were removed from the SG; and
- indications of tube damage associated with the loose parts.
- 10. Discuss the scope and results of any secondary side inspection and maintenance activities (e.g., in-bundle visual inspections, feed-ring inspections, sludge lancing, assessing deposit loading, etc.).
- 11. Discuss any unexpected or unusual results.
- 12. Provide the schedule for SG-related activities during the remainder of the current outage.
