Enclosure REQUEST FOR ADDITIONAL INFORMATION RELATED TO THE 2006 STEAM GENERATOR INSPECTION REPORT FIRSTENERGY NUCLEAR OPERATING COMPANY FIRSTENERGY NUCLEAR GENERATION CORP.
OHIO EDISON COMPANY THE TOLEDO EDISON COMPANY BEAVER VALLEY POWER STATION, UNIT NO. 2 DOCKET NO. 50-412 By letter dated February 2, 2007 (ADAMS Accession No. ML070360529), FirstEnergy Nuclear Operating Company (licensee) submitted information summarizing the results of the 2006 steam generator (SG) tube inspections at Beaver Valley Power Station, Unit No. 2 (BVPS-2). These inspections were performed during the twelfth refueling outage (2R12). In addition to this report, the Nuclear Regulatory Commission (NRC) staff summarized a conference call about the 2006 SG tube inspections at BVPS-2 in a letter dated November 9, 2006 (ADAMS Accession No. ML063100291). In order to complete the review, the NRC staff needs the following additional information:
- 1.
For the tube located at Row 36 Column 18 of SG B, listed on page B-18 of Attachment B to the February 2, 2007, letter, please provide the percent through wall measurement of the volumetric indication.
- 2.
As stated on page A-6 of Attachment A to the February 2, 2007, letter, please provide the cumulative number of indications detected in the tubesheet region as a function of elevation within the tubesheet.
- 3.
During the October 12, 2006, conference call, the licensee provided the scope and results of the secondary side inspection in SG B, but inspection of SG C had not yet commenced. If you could provide similar information for SG C, that would be fine. We are looking for a high level summary of your inspections and results.
See Question 10 in Attachment 1 of the NRC staffs letter dated November 1, 2006 (ADAMS Accession No. ML063060284).
- 4.
You indicate that two tubes (one tube in SG A and one tube in SG B) were plugged for data quality reasons. Please discuss how tube integrity was determined at the locations where the data quality was in question (e.g., were the tubes still able to be inspected or were they in-situ pressure tested).
- 5.
Attachment B to the February 2, 2007, letter, which lists tubes with indications of service induced degradation, includes many tubes that were not plugged. Please confirm that there are no degradation/flaws for those tubes listed as distorted support plate signal
2 with possible indication, non-quantifiable indication, and dent/ding with an indication (i.e.,
the only tubes with flaws are listed as percent through wall, single volumetric indication, single circumferential indication, multiple circumferential indication, and single axial indication).
