Subject:

Draft SER Section 2.5.5.3

Dear Sir:

The following comment appears in the Draf t SER Section 2.5.5.3, which was forwarded in Reference (b):

"To further assure the safe functioning of the revetment slopes during the life of the plant, the etaf f requires that the applicant commit to developing an appropriate inservice inspection and st.rveillance program for the revetments and to include the revetments as items to be inspected under the purview of USNRC Regulatory Guide 1.127, ' Inspection of Water Control Structures Associated with Nuclear Power Plants'."

In response to the above comment, we will revise FSAR Section 1.8, regarding our position on USNRC Regulatory Guide 1.127 (Revision 1, 3/78) as indicated on the attached annotated FSAR page (1.8-48) to include an appropriate inservice inspection and surveillance program for the flood protective structures.

The revision to FSAR Section 1.8 will be included in OL Application Amendm st 48.

Very truly yours, YANKEE TOMIC ELECTRIC COMPANY

Regulatory Guide 1.125 Physical Models for Design and Operation of (R2v. 1, 10/78) Ilydraulic Structures and Systems for Nuclear Power Plants Subrook does not have any safety-related hydraulic structures which directly interface with surface waters.

Some of the types of physical modeling studies included in Regulatory Guide 1.125, Rev. 1, were, however, used in the design and operation of non-safety related hydraulic structures and systems of the plant. A number of these studies were discussed with the NRC Staff at the testing facilities. Results of these studies have been transmitted to the NRC staff.

The physical modeling studies are further discussed in Section 3.4 of the environmental report.
