Subject:

Information Request Regarding Station Blackout, Unresolved Safety Issue A-44, Crystal River Unit 3 The NRC staff is currently addressing Unresolved Safety 'ssue (USI)

A-44, Station Blackout. The purpose of this work is to e.stablish the safety significance of an event resulting in a loss of all alternating current power and, if significant, to consider the need for any specific changes. Over the past several 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 determining 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 ' tudies such as AEC-00E-ES-002, NUREG/CR-0660, and s

NUREG/CR-1362.

The questionnaire (enclosure 1) requests information in tabular form and solicits data foy 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 simuld be entered.

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

Please find enclosed LER docunentation (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 8107200492 810709 se.uwig PDR ADOCK 05000302 F

Hr. J. A. Hancock 3) to our letter of itarch 6,1978 which requested related, but different, information. This is being forwarde'd for your information only ara should aid in preparing Tables 1 through 4.

In consideration of the time and effort necessary to obtain this information, the completten 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 effect is that our pcneric reliability estimates may be lower than that which actually exists.

The above information 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 reliability 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 f?anager 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.

Table 1 Reason for DG Operation and Scheduled Duration of Pun: This colu=n contains the differen: categories of diesel generator operation. The categories are structured such tha: the start and run condition's are si=ilar for 11 of the tests in a category. In this cplu=n, enter the scheduled run duration for each of the ces: categories. Also enter the number

~

of diesel genera:or starts that are done for each type of test. For exa=ple, if en the =enthly test the~re is one start from the local con-trols and one s: art fre= the Ye=ote controls, the nu=ber cf star:s per test is two.

If two or = ore diesels are started si=ultaneously for any reason, pleas 6 record it as a =ultiple start.

DG No.: Enter each diesel generator's identification nu=ber in this eclu=n as shown in the exa ple. ~

Nu=ber of Starts: Enter :he su= of the successful and unsuccese 1 star:

a::e: pts for each category. If there are several starts for u h test, include all of the=, but be certain to record the nu=ber of starts per test in cole =a one.

Nu=ber of Failures: Enter the su= of the failures for each category. A failure is counted if the objectives of :he tes: are net achieved. A subsyste: f,ailure that does not cause, failure of :he diesel genera.wr syste= is no: counted as a failure. If the diesel generator did not s: art, run, and load as required by the :est, a failure should be recorded. Hevever, if the diesel generator could have supplied power in so=e capacity f or an e=ergency, please explain in Table 3.

Fer exa=ple, if the diesel star:ed on the second atte=p: or the diesel was : ripped to repair a =iner oil leak : hat would not have been a proble: in an e=ergency, :his should be noted in Table 3.

Tercen: Leading of DG Oth*): Enter the percentage tha: the diesel is loaded for each category. The continuous kilowatt rating is considered to be 100%.

Dura:icn of Run 3efore 5:op for each DG Failure: Record the run-tine for each failure. If the diesel f ailed to start, the run-:1=e would be 0 min.

Identifica: ion of Failures: A:: ached to this questiennaire are abstrac:s of the LIRs rela:ed to the diesel generators. The abstrat:s are nu=bered starting with one.

Refer to this number to identffy the failures, but if there was a failure for which there is no abstract, assign the f ailure 'a nu=ber and include i: in Table 3.

Table 2 Rt. on for Dovu:i=e: Enter in this colu=n the categcries of schedule =ain-tenance :ha: =ake :he diesel generator unavailable for emergency service.

If the diesel generator is unavailable for e=ergency service during surveillance testing, report that also.

Table 2 (cont'd)

Ecurs of Downtime: Enter the number of hours that the diesel gererator is unavailable for emergency service. Report the hours under the column reae:or shutdown or reactor not shutdown as appropriate.

Comments: Comment on time to return to service after maintenance has begun, or other pertinent infor=ation.

Table 3 LIR Abstract No. (Refer to a:: ached LER Abstracts): The a:: ached LEls are nu=bered starting f cm one. Refer to :his LER numbe, in column Each LER abs::act should have an en:ry in this table.

If one.

there was a failure not included in the attached abstrac:s, please assign it a number and enter it in this table.

Downtime Hours:

E=;e: the nu=ber of hours that the diesel generate is unavailable for emergency service.

Subdivide these total hours into ::cubleshco:ing, parts delivery, and repair or replace =ent.

Co==ents: Use this celu=n to ec==ent on the downtime and the failure.
