SUBJECT:

Tendon Surveillance REF: 1) Letter, Denise to Lee, 7/20/84, G-84252

2) Letter, Warembourg to Johnson, 6/15/84, P-84174

Dear Mr. Johnson:

This letter confirms a telephone conversation between Mr. Chuck Fuller, of my staff, and Mr. Phil Wagner which took place on August 6, 1984.

By way of Reference 1), you suggested proposed changes to the Fort St. Vrain Technical Specification SR 5.2.2 - Tendon Corrosion and Anchor Assemblies Surveillance. My staff has reviewed the suggested surveillance test, and has concluded that some requirements of the test are not physically possible to do. Specifically, I am referring to the requirements that state that the " entire population" of tendons be visually examined and/or liftoff tested. As I have previously expressed, a number of the tendon end caps are located s such that the caps cannot be removed for visual examinations. In other cases, the end cap may be removable for visual examination purposes, but other interference prevents accessing the tendon for lift off tests.

Obviously, I can not submit a proposed technical specification surveillance test which I am not capable of performing. The problam, then, is to define which end caps are accessible, which end caps can be made accessible via reasonable design modifications, and which end caps can not be made accessible without major, cost prohibitive design modifications. I have directed my staff to make such a determination. /

2-By way of the above referenced telephone conversation, Mr. Wagner was informed that the completion of the tendon end cap accessibility servey would require a postponement in the submittal of a technical specification change request. Mr. Wagner was agreeable to this approach. Therefore, we will submit the technical specification change request by September 30, 1984.

If you have any questions, please call me or Mr. Chuck Fuller at (303) 785-2223.

Very truly yours,
