FW: Planned Inspections for North Anna Unit 1
- Ken, Due to the recent earthquake and subsequent events at NA, they have decided to perform eddy current on one SG in Unit I to ensure integrity prior to startup and I will be performing the SGISI for SG A only.
-Their planned inspections are in the email just below.
Is there anything outside of the normal items that I should be paying particular attention to?

BeTow I've identified the scope of inspections to be performed on Steam Generator A in Unit 1 at North Anna Power Station during the period September 10 through September 17. I also provided a brief description of our inspection schedule. The degradation assessment is currently out for review and comments and will be ready for your review next week.
Tony SG "A" ONLY The primary side work scope is defined to include:
- i. There will be no visual inspection for evidence of leakage of previously installed plugs in the hot and cold legs since there are no installed plugs.
ii. Bobbin coil inspection of the full length of all tubes in service, except for the U-bend region of Row 1 tubes.
iii. Rotating coil inspection of the U-bend region of all Row 1 tubes in service (approximately 98 tubes).
iv. Rotating coil inspection of the hot leg top of tubesheet region (TSH +3 to TSH -3) of 993 tubes. The tubes selected for inspection will include a 50% sample of tubes in the defined special interest areas as shown in the Dominion Outage Plan documents.
- v. Rotating coil inspection of the cold leg top of tubesheet region (TSC +3 to TSC -3) of 570 tubes.
vi. Rotating coil inspection of 100 additional locations of interest as defined by Dominion.
The secondary side base scope work includes:
I. SSI/FOSAR at the top of the tubesheet if possible loose parts are detected by ECT ii. Visual inspection of the internal blowdown piping and wrapper supports at the top of the tubesheet iii. steam drum visual inspection iv. 7th TSP visual inspection
- v. J-nozzle visual inspections The primary work scope is scheduled to begin on Saturday September 10 mid day and end on Saturday September 17. We will have a common day off on Sunday September 11 and we are only running 1 robot. Bobbin inspections will last about 3 to 31/2 days and RPC exams will last another 3 to 3 2 days. Dependent on having no equipment issues we should finish by the end of that week.
