Subject:
Containment Vessel Tendon Evaluation Program Ginna Nuclear Power Plant Docket-No.'0-244-
Dear Mr. Crutchfield:
This letter is in response to your letter dated March 8, 1983 and addresses comments and specific concerns raised by the NRC staff regarding the reasons for loss of prestress in the Containment Vessel Tendons.
Additional information is presented which supports our previous conclusion that stress relaxation of the tendon wires is the most significant, cause of the larger than predicted force losses.
The 1983 Tendon Surveillance is tentatively scheduled for mid-July.
A report on the surveillance will be issued within 90 days after its completion.
Very truly yours, W(~tug~
