NUCLEAR REGULATORY COMMISSION Washington, D. C. 20555 Attention: Mr. J. R. Miller, Chief Operating Reactors, Branch 3 Gentlemen:

DOCKET NOS. 50-266 AND 50-301 MODIFICATION TO TECHNICAL SPECIFICATION CHANGE REQUEST NO. 98 SURVEILLANCE OF CONTAINMENT TENDONS POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 In a letter dated May 2, 1984 Wisconsin Electric Power Company requested license amendments to incorporate revisions and additions to the Point Beach Nuclear Plant Technical Specifi-cations for testing and surveillance of the containment structure tendons. The purpose of the changes was to improve the tendon surveillance program by providing for random sampling of tendons to be tested and to specify tendon testing in accordance with the recommendations of.the NRC regulatory guidance.

In a letter dated July 24, 1984 the NRC staff provided comments on our proposed tendon surveillance specifications and requested that licensee resubmit these specifications to incorporate these comments. The NRC pcsitions were subsequently clarified in several telephone calls from Messrs. T. G. Colburn and C. P. Tan of your staff.

i Attached is a revision to our proposed tendon surveillance specification which includes the changes requested by the NRC staff. Changes to the May 2 license amendments application are identified on the attached pages by double margin bars and are

! sunmarized as follows:

1. Section D has been added to Specification 15.3.6 to provide a limiting condition-for operation on containment structural integrity.
2. Specification 15.4.4.VII.A was revised to require that one tendon from each group be subjected to retesting at each physical inspection in order to develop a test history and to permit correlation of test data.

3. Specification 15.4.4.VII.C. (2)b (ii) . was expanded to include a'dditional suggestions for actions to be considered if a tendon'prestressing force falls below the predicted lower-limit.
  • ;4. EItenE(iv) was added to the above. specifications to

< provide a- listing of the-minimum design value tendon force' adjusted for elasticilosses for each of the three tendon groups.

5.- Specification l5.4.4.VII.C d

(2) d. was revised to specify the minimum' required . tendon wire tensile strength and

, < 1 action ~ to bi taken if that minimum is not. satisfied.

6.- Specification 15.424.VII;C'2)e ( was revised to better defineEthe operability re'quirements for the sheathing

, filler grease'; .

As required 'by =10 CFR 50.91(a) (1) , we have examined these' changes to our previously submitted Technical Specification change - request -to' . determine whether or not- these proposed changes

-involve a significant hazards consideration. .Since each of these l changes involves additional limitations or restrictions not previously

' contained in the proposed or existing' specifications, we conclude,

"_ :in conformance with the guidelines provided in 48 Federal Register

, 14870, that these revisions do not constitute a significant hazards l consideration.

Enclosed are three signed originals and forty copies

'of'this modification to our. license amendments application and 11etter of May.2. As discussed with yourfstaff, we are. proceeding with the 1984 tendon inspection utilizing procedures.which incorporate all provisions of these proposed Technical Specification changes.

Please contact _us if you have any questions concerning this submittal.
