Dear Mr. Denton:

This letter and its attachments respond to Mr. D.

G. Eisenhut's letter of November 20, 1980 regarding Technical Specification surveillance requirements for safety-related snubbers.

Attachment Nos.

1 and 2 contain the revised Technical Specification pages for D. C. Cook Unit Nos.

1 and 2, respectively.

As noted in the footnotes on page 3/4 7-23 of the Attachment to Mr.

Eisenhut's letter, the value "c" used in the determination of the number of snubbers to be tested was intended for use in plants with large numbers of safety-related snubbers

( +500).

Since each Unit of the Cook Plant utilizes approximately 100 safety-related

snubbers, those portions of the

'sample'echnical Specifications referring to "c" in Mr.

Eisenhut's letter have been deleted.

Similarly, since mechanical snubbers are not used in safety-related systems at Cook Plant, the

'sample'pecifications have been modified. to refer only to hydraulic snubbers.

Other minor modifications have been made to the

'sample'pecifications to accommodate insertion into the existing Cook Plant Specifications.

The Technical Specifications contained in Attachment No.

1 reference Specification 4.0.5 which does not exist in the present Unit No.

1 Specifications.

However, we plan to submit in the near future revisions.'o the Unit No.

1 Technical Specifications which will incorporate a Specification 4.0.5 very similar to the existing Unit No.

2 Specification.
