Subject:
Infomation Request Regarding Station Blackout, Safety Issue A-44, Cooper Nuclear Station The NRC staff is currently addressing Unresolved Safety Issue (USI)
A-44, Station Blackout. The purpose of this wo k is to establish the safety sig iificance 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 infomation requests have been forwarded which requested infamation that is be1..g 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 ouestionnaire has been prepared to provide accurate operating exnerience to serve as a basis for such a detemination. Mc ae specifically, its purpose is to obtain nore detailed data than were available in previous diesel generator studies such as AEC-00E-ES-002, NUREG/CR-0660, and fiUREG/CR-1362.
The questionnaire (enclosee 1) requests infomation in tabular fom and solicits data for the vears 1976 through 1980, inclusive. There are four tables enclosed:
(1) Diesel Generator Operations Data, (2) Diesel Generator Scheduled Down Time Record, (3) Diesel Cenerator Unscheduled Down Time Record, and (4) Onsite Emergency Diesel Generator and Auxiliary Equipment flodification 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 that only Licensee Event Report (LER) infomation is sought, data on all diesel generator malfunctions, independent of whether an LER was prepared, is requested.
Please find enclosed LER docunentation (enclosure 21 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 respor.se (enclosure 8107300286 810720 PDR ADOCK 05000298 F

c l
t Mr. J.14. P11 ant !
- 3) to our letter of March 6,1978 which requested related, but different, infomation. This is being forwarded for your information only and i
should aid in preparing Tables 1 through 4.
In consid^ ration of the time.and effort necessary to obtain this infomation, i
the completion of Table 4 should be considered voluntary. However,it I
should be noted that if operational and hardware modifications are not i
i identified, the positive or negative influence of these features on
~
emergency alternating current power reliability may be lost in the i
i evaluation of the data. The expected effect is that our generic reliability estimates may be lower than that which actually exists.
L bove information is requested in accordance with Sections 103.b.(3)
' 7.51.c of the Atomic Energy Act of 1954, as amended. To meet our scLdule requirements for the resolution of USI A-44 and to incorporate j'
as much real experience as possible into the reliability model for emergency power systems, it is requested that your response be provided
[
.within 120 days of the receipt of this letter. However, if this schedule is inconsistent with priority requirements for other licensing work, I
please provide us with your proposed date of response within 30 days.
i 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 l
onsite alternating current power sources can be made.

Mr. P. Baranowsky has been designated Task Manager for USI A-44. ohould you have any questions, please feel free to contact him at (301) 443-i 4

' EXPLANATION / CLARIFICATION Table 1 Reason for DG Operation and Scheduled Duration of Run: This column contains the different r.ategories of diesel generator operation. The categories are structured =dch that the start and run conditions are similar for all of the tests in a category. In this column, enter the scheduled run duration for c 'h of the test categories. Also enter the number of diesel generator starts that are done for each type of test. For example, if on the monthly test there is one start from the local con-trols and one start from the remote controls, the number of starta per test is two.
If two or more diesels are started simultaneously for any reason, please record it as a multiple start.
DG No.:
Enter each diesel generator's identification number in this colum as shown in the example.
Number of Starts: Enter the sum of the successful and unsuccessful start attempts for each category. If there are several starts for each test, irclude all of them, but be certain to record the number of starts per test in column one.
Number of Failures: Enter the sum of the failures for each category. A fatlure is counted if the objectives of the test are not achieved. A subsystem f ailure that does not cause failure of the diesel generator system is not counted as a failure. If the diesel generator did not start, run, and load as required by the test, a failure should be recorded. However, if the diesel generator would have supplied power in some capacity for an emergency, please explain in Table 3.
For example, if the diesel started on the seccnd attempt or the diesel was tripped to repair a minor oil leak that would not have been a problem in an emergency, this should be noted in Table 3.
Percent Loading of DG CKW): Enter the percentage that the diesel is loaded for each category. The continuous kilowatt rating is considered to be 100%.
Duration of Run Before Stop for each DG Failure: Record the run-time for each failure. If the die < 1 failed to start, the run-time would be 0 min.
Identification of Failures: Attached to this questionnaire are abstracts of the LERs related to the diesel generators. The abstracts are numbered starting with one.
Refer to this number to identify the failures, but if there was a failure for which there is no abstrict, assign the failure a number and include it in Table 3.
Table 2 Reason for Downtime: Enter in this column the categories of schedule main-tenance that make the diesel generator unavailable for emergency service.
If the diesel generator is unavailable for emergency service during surveillance testing, report that also.
s Enclorura 1 - Paga 6.
2 Table 2 (cont'd)
Hours of Downtime: Enter the number of hours that the diesel generator a for emntgency service. Report the hours under the f-1..e or shutdown or reactor not shutdown as appropriate.
c
'er Coraments : Comment on time to return to service after maintenance has
~
begun, or other pertinent information.
1911.1 LER Abstract No. (Refer te attached LER Abstracts):
The attached LERs are numbered starting from one.
Refer to this LER number in column one.
Each LER abstract should have an entry in this table.
If
,.pp there was a failure not included in the attached abstracts, please asstgn it a number and enter it in this table.
Downtime Hours: Enger the number of hours that the diesel generator is unavailable for emergency service. Subdivide these total hours into troubleshooting, parts delivery, and repair or replacement.
Comments: Use this column to comment on the downtime and the failure.
If the reported failure was only a technical specification violation, but would not be a complete failure of the diesel generator to supply power or would only be a delay, clease elaborate in this Column.
Table 4 Equipment or procedure modified: List in this column the equipment or procedures related to the emer7ency onsite pLwer system that have been modified since the reactor became critical.
Date of Mod.:
Enter the date that the mod!.fication was completed.
Reason for Modification and Desired Improvement: Report the reason for the modification and the desired or observed improvement in the system.
Description of Modification: Briefly describe what modification was made.
