Docket Nos. 50-424-OLA-3,50-425-OLA-3 Gentlemen:

At the last prehearing conference, you expressed interest in receiving a copy of the procedure defining terms that were used in the Vogtle Diesel Generator Start Log, Exhibit 16 to the 01 report. In response to this request, I am enclosing a copy of VEGP Procedure No. 55038 C, Rev. 2, " Diesel Start Log," which is the version that was in effect in the rele-vant time frame. Many of the defined terms are derived from Regulatory Guide 1.108, which I am also enclosmg for your convenience.

Sincerely, David R. Lewis Counsel for Licensee cc (w/ encl.): Service List 9407080038 940628 A

" PERIODIC TESTING 0F DIESEL GENERATOR UNITS USED AS ONSITE ELECTRIC POWER SYSTEMS AT NUCLEAR POWER PLANTS" The demonstration of diesel generator unit reliability (Regulatory Position C.2.a(9)) was inadvertently placed in Revision 1 of Regu-latory Guide 1.108 so that such demonstrations appeared to be called for at least every 18 months in addition to. the intended demonstration during the plant preoperational test program.

Therefore, Regulatory Position C.2.a(9) should be revised to read:

(9) During the plant preoperational test program only, demonstrate the required reliability by means of any 69 consecutive valid tests (per plant) with no failures, with a minimum of 23 or 69/n tests, whichever is the larger, per diesel-generator unit (where n is equal to the number of diesel generator units of the same design and size).

O DIESEL START LOG 1.0 PURPOSE 1.1 The purpose of this procedure is to provide the tracking mechanism required to evaluate the reliability of the Diesel Generator Unit".

This procedure also will provide the feedback required to adjust testing intervals and the reporting mechanism to the required regulatory agencies which may be required when failures occur.

1.2 This procedure satisfies the following Technical Specifications:

Table 4.8-1 Section 4.8.1.1.3 2.0 PREREQUISITES OR INITIAL CONDITIO*tS 2.1 A diesel start was initiated by either automatic signal, including those from bona fide signals, or manual signals.

2.2 Tests will be performed using procedure 14980-1, 14985-1,13145-1,14980-2,14985-2, or 13145-2 and results shall be recorded.

The results of the test shall be transmitted to the ESS for independent review and update of the Diesel Generator Log.

" DIESEL GENERATOR UNIT" Consists of the following components:

The engine, generator, combustion air system, cooling water system up to the supp'ty, fuel supply syrte, lubricating oil system, starting energy sources, autostart controls, manual controls and the diesel generator breaker.

3.3

" VALID TESTS AND FAILURES" a.

All start attempts (automatic, including those from bona fide signals, or manual) that result in a failure to start, except as noted in (2) below, should be considered valid tests and failures.

L b.

Unsuccessful reart and load attempts that can definitely be attributed to operating error, to s aurious operation of a trip that is bypassed in the emergency operating mode, to malt' unction of equipment that is not operative in the emergency operating mode (e.g.,

synchronizing circuitry) or is not part of the defined diesel generator unit design should not be considered valid tests or j

failures.

g c.

Successful starts, including those initiated by bona fide signals, followed by successful loading (sequential or manual) to at least 50% of continuous rating and continued operation for at least one hour should be considered valid successful tests.

r d.

Successful starts that are terminated intentionally without loading, as defined in (3) above, should not be considered valid tests er

failures, e.

Successful starts followed by an unsuccessful loading attempt should be considered valid tests and failures, except as noted in (2) above, i

Tests performed in the process of trouble shooting should not be considered valid tests.

Tests that are performed to verify correction of the problem should be considered valid tests and successes or failures, as appropriate.

h.

Cranking and venting procedures that lead to the discovery of conditions (e.g., excessive wate: or oil in a cylinder) that would have resulted in the failure of the diesel generator unit during test or during response to a bona fide signal should be considered a valid test and failure.

5.6 From Procedure'll885-1 or 11885-2 determine for the time period covered the total Engine Run Time at no

load, 0 to 25% load, 25 to 50% load, 50 to 75%

load, 75 to 100% load and 100% load.

5.7 From Data Sheet 3 of procedure 14980-1 or 14980-2 Data Sheet 1 of this procedure and other sources (e.g.

Operator's Log), record all time the Diesel Generator was unavailable.

5.8 Record current Total Run Time from the Engine Hourr..ater at the Local Engine Control Panel.

5.9 From Diesel Geperator Start Information Sheets for the calendar period covered, determine if there were any repeat failureimechanisms, repeat human errors or common mode failures. If there were any, give details in comments section.

Attach additional pages, if l

necessary.

Once Per 7 Days See definition of VALID TESTS & FAILURES.

For the purposes of determining the required test frequency, the previous test failure count may be reduced to zero if a complete diesel overhaul to like-new condition is completed, provided that the overhaul, including appropriate post-maintenani:e operation and testing, is s?ecifically approved by the manufacturer and if acceotable reliability has been demonstrated.- The relisiility criteria shall be the successful completion of 14 consecutive tests in a l'

single series.

Ten of these tests shall be in accordance with the routine Surveillance requirements specified ir..rocedure 14980-1 and four tests in accordance L1th the 6 month (184-day) testing requirement specified in procedure 14980-1.

If this criteria is not satisfied during the first series of tests, any alternative criterion to be used to transvalue the failure count to zero requires NRC approval.

The associated test frequency shall be maintained until seven (7) consecutive failure free demands have been performed and the number of failures in the last 20 valid demands has been reduced to one (1).
