SUBJECT:

SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE INSPECTION SEQUOYAH NUCLEAR PLANT REPORT NOS. 50-327/94-01 AND 50-328/94-01 This is to advise you of a special inspection initiative that is being performed at operating reactors.

It will include an-inspection at your.

'i Sequoyah site. The initiative is entitled the " Service Water System i

Operational Performance Inspection (SWSOPI)."

1 The purpose of the inspection is to systematically evaluate the performance ofi

]

your emergency raw cooling water system.

Inclusive in 'the. inspection, will-be -

a comprehensive review of system design, maintenance, operation, and' testing.

1 The inspection will verify the status of your. initiatives associated with.

Generic Letter 89-13, " Service Water System Problems Affecting Safety Related

.j Equipment." ~ In addition, the inspection will encompass an evaluation of your engineering and technical support activities as they relate to the' emergency raw cooling water system.

1 This is a team inspection with up to seven individuals expected to be _ _

involved: one team leader, and six subject matter. experts. _ Somewhere.during i

the second week in January, a large portion of the' team members will visit your site to_ accomplish preliminary inspection activities. The entire team will be onsite the weeks of January 24 and February 7,1994.

j To improve the effectiveness of the inspection.and lessen its impact'upon your i

staff, there are a number of actions the team is requesting.

First, since overview presentations have been an efficient means to communicate' relevant information, informal presentations from your staff during the week of ~

January 24, 1993, describing the emergency raw cooling water system design and.

a i

operations, significant modifications since original licensing, actions in

~

response to Generic Letter 89-13, and a history of system problems, are encouraged. Second, a_ tour /walkdown of the emergency raw cooling water system during the week'of January 24, 1993, by the cognizant system and design

.{

engineer, would be appreciated. Third, the team will be reviewing a;1arge amount of records,. procedures, and design documents. Therefore, a request'for-j

OCT '2 9 HMI3 information is provided as an attachment to this letter. There are-two categories of information. The first is information needed prior to i

January 3, 1993. The second is information to be available and/or easily

-i retrievable when the team is onsite.

l l

The team leader for this inspection will be Mr. W. G. Rogers from Region II.-

Mr. Rogers will contact members of your staff in the near future to discuss the details of the inspection.

If you have any questions in the interim regarding the inspection program, we will be pleased to discuss them with you.

Sincerely, i
