Subject:
Containment Tendon Surveillance Program R.
E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Crutchfield:
Our letter dated April 29, 1981 described the containment tendon surveillance program planned to begin this month.
This letter revises that program and the testing schedule based on the conference call held between our staffs on June 3, 1981.
The proposed program included testing of 14 tendons.
At the request of your staff, tendons 63, 74, and two other, randomly selected tendons have been added to the program.
We have selected tendons 21 and 125 to be added to the test program, bringing the
.total number of tendons to be tested to 18.
As agreed with your staff, if the lift-offforce for any tendon is less than 60%
GUTS, the two adjacent tendons will be tested.
After the tendon surveillance tests, we will continue our program of monitoring four tendons with load cells.
The tendon wire tests currently being performed at Lehigh University are scheduled to continue until early 1982.
We are reviewing whether sufficient data will be available by August 1981 to draw conclusions regarding wire relaxation properties.
A report will be submitted to you as soon as possible following completion of the various test programs and evaluation of the results.
