a, lJUL 2 0 M Docket No. 50-203 Mr. A. Victor fiorisi Boston Edison Company ft/C Muclear 800 Boylston Street Boston, Massachusetts 02199
Dear Mr. Morisi:
Subject:
Infomation Request Regarding Station Blackout, Unresolved Safety Issue A-44, Pilgrim Huclear Power Station Unit No.1 The NRC staff is currently addressing Unresolved Safety Issue (USI)
A-44 Station Blackout. The purpose of this work is to establish 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 nast several years infomation requests have been forwarded which requested information 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 detemination. More specifically, its purpose 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-1352 The questionnaire (enclosure 1) requests infomation 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 S:heduled Down Time Record, (3) Diesel Generator Unscheduled Down Time Record, and (4) Onsite Ewergency 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 that only Licensee Event Report (LER) infomation is sought, data on all diesel generator malfunctions, independent of whether an LER was prepared, is requested.
i 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

Mr. A. Victor !brisi 3) to our letter of March 6,1978 which requested related, but different, infomation. This is being forwar/ed for your infomation only and should afi 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 'f 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 generic 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 requirenents for the resolution of USI A-44 and to incorporate as much real experience as possible into the reliability model for energency 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, please provide us with your pr7 posed 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. Caranowsky 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.

EXPLANATION / CLARIFICATION
{
Table 1 Reason for DG Operation and Scheduled Duration of Run: This column contains the different categories of diesel generator o,peration. The categories i
I are structured such 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 each of the test ettegories. Also enter the number i
of diesel generator starts that are done for each type of test. For example, if on the monthly test there is one start frcm the local con-trols and one start from the remote controls, the number of starts per test is two.
If two or more diesels are started simultaneously i
for any reason, please record it as a multiple start.
I DG No.: Enter each diesel generator's identification number in this column I
as shown ir P.he example.
Number of Starts: Enter the sum of the successful and unsuccessful teart atte= pts for each category. If there are several starts for each test, include all of them, but be certain to record the number of starts per I
test in column one.
Number of Failures: Enter the sum of the failures _for each category. A 3
i failure is counted if the objectivec of the test are not achieved. A subsystem f ailure that does not cause failure of the diesel generator l
system is not counted as a failure. If the diesel generator did.not j
start, run, and load as required by the test, a failure should be i
recordad. 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 second 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 3efore Stop for each DG Failure: Record the run-time for each failure. If the diesel failed to start, the run-time would be 0. min.
Identification of Failures: Attached to this questionnaire are abstracts of the Leas related to the diesel generators. The abstracts are numbered starting v1th one. Refer to this number to identify the failures, but if there was a failure for which there is no abstract, 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 serv +.ce during surveillance testing, report that also.

Hours of Downti:ne: Enter the number of hours that the diesel generator is unavailable for emergency service. Report the hours under the column reactor shutdown or reactor not shutdown as appropriate.
Co=nents: Comment on time to return to service after maintenance has begun, or other pertinent information.
Table 3 LER Abstract No. (Refer to 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 there was a failure not included in the attached abstracts, please assign it a number and enter it in this table.
Downtime Hours:
Inter che number of hours that the diesel generator is unavailable for estrgency service. Subdivide these total hours into troubleshooting, sarts delivery, and repair or replacement.
Cocments: Use this colun to comment on the devutime and the failure.
