Dear Mr. Abel:

July 9, 1981

Subject:

Infonnation Request Regarding Station Blackout, Unresolved Safety Issue A-44, Dresden Uni ts 2 and 3 The NRC staff is currently cfddress ing Unreso 1 ved Safety I ssoe (US t) }\\'!"44, Station Blackout. The purpose of this work is to establish the ~afety significance of an event resulting in a loss of all alternating curr.ent power and, if significant, to consider the need for any, specific changes. Over the past several years information requests have been forwarded which requested information that is being used in the USI . analysis.* Your interest.and cooperation fn the past have been appreciated. At this time the USI A"'.'44 effort is being directed toward detennining 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 generator studies such as AEC.;.OQE-ES-002, NUREG/CR-0660, and NUREG/CR-1362. The questionnaire (enclosure 1) requests 1nfonnation in tabular form and solicits data for the years 1976 through 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 examples of completed tables as well as a clarification of what should be *entered. Please note that, although it may appear th~t only Licensee Event Report (LER) infonnation is sought, q~ta on'all d'iesel 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 which have not been enclosed. Finally, please . find enclosed a copy of the appropriate portions of your response (enclosure 8107:210148 810709 ~: PDR ADOCK 05000237 :~f F PDR \\Cf\\ (11;~.

3) to our letter of March 6, 1.978 which req~ested related, but different,.

infonnation. This is being forwarded for yqur infonnation only and should aid in preparing Ta bl es 1 through 4. t -.~-- .Yn consideration.of the time and effort nece.ssary tO obtain this infonnation, the.completion Qf Table 4 should be considered voluntary. However, it . sho~l~ be noted** that if operational and hardware modifications are not identified,.. th*e positive or negative influence of these features on emergency alternating current" power reliability may be lost in the e.valuation of the data. The expected-effect is that our generic reliability estimates may be lower than that which,actually exists. _The ~bove infonnation is requested in a~corc:lance 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 1ncor.porate as much real experience as possible into the reliability model* for emergenc,YpQwer systems, it is requested that your response be P.rovided withil)*_ 90 days of the receipt-of this letter. However, if this s~hedule

  • is*inconsistent with pr,iority 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 ~lternating 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 fi:ee_*to contact him at (301) 443-5~21. Your time and efforts are appreciated.
