Y July 9, 1981 Docket Nos. 50-321 and 50-166 Mr. J. Beckham, Jr.

(15/333) Vice President - Engineering Georgia Power Company Post Office Box 4545 Atlanta, Georgia 30302

Subject:

Infor nation Request Regarding Station Blackoat, Unresolved Safety Issue A-44, Hatch Units 1 and 2 The NRC staff is currently addressing Unresolved Safety Issue (USI)

A-41, Station Blackout. The purpose of this work is to establish the safety significance of an event resultine; in a loss of all alternating current power and, if significant, to consider the need for any specific changes. Ovec the past several year information recuests have been forwarded which requested informatiori that is being used in the USI analysis. Your interest and cooperation in the past have been% appreciated.

At this time the USI A-44 effort is being directed toward determining the reliability of the onsite standby diesel generators. The enclosed cuestiennaire has been prepared to provide accurate operating experience tc serve as a basis for such a determination. More specifically, 'ts puroose is to obtain more detailed data than were available in previous diesel generator studies such as AEC-00E-ES-002, NUREG/CR-0660, and NUREG/CR-1362.

The questionnaire (enclosure 1) requests information in tabular form and solicits data for the years 1976 through 1980, inclusive. There are fcur tables enclosed:

(1) Diesel Generator Oceraticns Data, (2) Diesel Generator Scheduled Down Time Record, (3) Diesel Generator Unscheduled Down Time Record, and (4) Onsite Emergency Diesel Generator and Auxiliary Equipment Modification Record. Also enclosed are examples of completed tables as well as a clarification of what should be entered.

Please note that, although it may apoear that only Licensee Event Report (LER) information is sought, data on all diesel generator malfunctions, independent of whether an LER was prepared, is reouested.

Please find enclosed LER documentation (enclosure 2) presently docketed for your tacility. You are requested to review these and to indicate if there are other reports whian have not been enclosed. Finally, please find enclosed a copy of the appropriate portions of your responte (enclosure 81072004s3 sto799 hDRADOCK 05000321 PDR

3) to our letter of March 6,1978 which requested related, but different, information. This is being forwarded for your informatica only and should aid in preparing Tables 1 through 4.

In consideration of the time and effort necessary to obtain this information, the completion of Table 4 should be considered voluntary. However, it should be noted. that if operational and.bardware modifications are not identified, t'he positive or negative influence of these features on emergency alternating current power, reliability may be lost in the evaluation of the data. The expected effect is that our gereric reliability estimates may be lower than that which actually exists.

The above information is requested in accordance with Sections 103.5.(3) and 161.c of the Atomic Energy Act of 1954, as amended. To meet ot.r schedule requirements for the resolution of USI A-4a and to incorporate as much real experience as possible into the reliability model for emergency power systems, it is requested that your response be provided within 90 days of the receipt of this letter. Hcwever, if this schedule is inconsistent with priority requirements for other licensing work, please provide us with your proposed date of response within 30 days.

We plan to complete our analysis of this data by February 1982. Your data should be provided by that time so that an accurate assessment of onsite alternating current power sources can be made.

Mr. P. Saranowsky has been designated Task Manager for USI A-44.

Should you have any questions, please feel free to contact him at (301) 443-5921. Your time and efforts are appreciated.

Sincerely, f
