Dear Mr. Barton:

Subject:

Information Request Regarding Station Blackout, Unresolved Safety Issue A-44, Farley Unit 1 The NRC staff is currer.tly addressing Unresolved Safety Issue (USI) A-44 Station Blackout. The purpose of this work is to establish the safety significance of an eveat resulting in a loss of all alternating current power and, if significant, to consider the need for any specific changes. Over the past saveral years information requests have been forwarded which requested infomation 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 detemining the reliability of the onsite standby diesel generators. The enclosed questionnaire has been prepared to provide accurate operating experience to serve as a basis for such a determination. More specifically, its purpose is to obtain more detailed data than were available in previous diesel cenerator studies such as AEC-00E-ES-002, NUREG/CR-0660, and MUREG/CR-1362.

The questionnaire (enclosu.. i) requests infomation in tabular form and solicits data for the years 1976 tnrough 1980, inclusive. There are four tables enclosed:

(1) Diesel Generator Operations 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 exanples of completed tables as well as a clarification of wht.t should be entered. Please note that, although it may appear that only Licenseo Event Report (LER) infomatior.

8, sought, data on all diesel generator malfunctions, independent of whether an LER was prepared, is requested.

Please find enclosed LER documentation (enclosure 2) presently docketed for your facility. You are requested to review these and to indicate if there are other reports - ich have not been enclosed. Finally, please find enclosed a copy of the appropriate portions of your response (enclosure 8107220012 810709 PDR ADOCK 05000348 F

information. This is being forwarded for your information only and should aid in preparing Tables 1 through 4.

In consideration of the time and effort necessary to obtain this infomation.

the. completion of Table 4 should be considered voluntary. However,it should be noted that if operational and hardware modifications are not identified, the positive or negative influence of these features on emergency alternating current power reliability may be lost in the evaluation of the data. The expected affect is that our generic reliability estimates may be icwe= than that which actually exists.

The~above infonention is requested in accordance with Sections 103.b.(3) and 161.c of the Atomic Energy Act of 1954, as amended. To meet our schedule requirements for the resolution of USI A-44 and to incorporate as much real experience as possible into the roliability model for emergency power systems, it is requested that-your response be provided within 90 days of the receipt of this letter. However, 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. Baranowsky 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.
