SUBJECT:
Calvert Cliffs Nuclear Power Plant Unit Nos. 1 & 2; Docket Nos. 50-317 & 50-318 2005 Steam Generator Tube Inspection Results Report
REFERENCE:
(a) Calvert Cliffs Nuclear Power Plant Units 1 and 2 Technical Specification 5.6.9.b Reference (a) requires that we report, on an annual basis, the results of the steam generator tube inservice inspection conducted in the past year.
This letter provides the results of the steam generator tube inspection conducted on Calvert Cliffs Unit 2 in 2005. This inspection was the first in-service inspection following steam generator replacement.
There were no inspections conducted on the Calvert Cliffs Unit I Steam Generators in 2005. This report includes the number and extent of tubes examined and indications identified.
Inspection Scone:
The inspection of Calvert Cliffs Unit 2 Steam Generators (21 & 22) was conducted using bobbin coil and motorized rotating plus point inspection technologies. All distorted bobbin coil indications were dispositioned with the plus point probe. The table below identifies the number and extent of the tubes inspected.

Attachment (1) lists the upper bundle tube support wear indications detected with the bobbin coil and confirmed with the motorized rotating plus point probe. No steam generator tubes were found with crack-like indications. There were no tubes plugged in SG 21 during the 2005 inspection. During the pre-service examination at the manufacturing facility, three tubes were plugged in SG 21. To date, a total of three tubes have been plugged in SG 21. There were no tubes plugged at the manufacturing facility in SG 22. A total of 29 tubes were plugged and stabilized in SG 22. All of the tubes in SG 22 were plugged and stabilized due to loose parts concerns found during the 2005 inspection. To date, a total of 29 tubes have been plugged in SG 22.
Should you have questions regarding this matter, please contact Mr. L. S. Larragoite at (410) 495-4922.
Very truly yours, sŽph E. Pollock Plant General Manager JEP/CAN/bjd
