Dear Mr. Denton:

f The purpose of this. letter is to further clarify our letter of November 22, 1978, Serial No. 646, concerning survey monitoring and Technical Specification surveillance requirements. Attachment I to that letter contains 27 " problem t

survey points." Five of the points relate to the Service Water System in that point 7 is on the Service Water Pump House and points 15,16,17, and 18 are

{

located on the service water piping at the Service Water Pump House.

j As explained in our letter, many of the survey points differ with respect I

to the established base line survey compared to the bases stated in the Techni-l cal Specification.

For instance, Plant Systems Bases 3/4.7.12 states that i

"The first survey was conducted in May 1976 to establish a base value for all points." Points 15, 16, 17, 18 were not established until July 1977, while i

point 7 was first established in November 1975. These dates, of course, are j

not the same as the May 1976 date stated in the-bases for the Technical Speci-I fication. This situation can be rectified easily with a notation in Table 3.7-5 L

or by a change in the bases section of the Technical Specification.

I I

This situation constitutes the totality of the " problem" associated with Points 7,15,16,17, and 18. There are no safety implications in using dates for points established in a time frame different from May 1976.

t i

A change in the Technical Specification to reflect these other dates has

~

not and would not affect the service water piping, the service water piping expansion joint, or the service water pump house. None of these systems, or structures associated with these systems, is in any way affected from a safety i

standpoint for the type of problem described in this letter.

l Very truly yours, f
