1 V0GTLE ELECTRIC GENERATING PLANT LICENSEE EVENT REPORT LQ11.0F 0FFSITE POWER LEADS TO SITE AREA EMERGENCY j
O In accordance with 10 CFR 50.73, Georgia Power Company hereby submits the enclosed revised report related to an event which occurred on March 20, 1990.
This revision is necessary to correct the information related to the number of successful Diesel Generator starts subsequent to the comprehensive test program as discussed in the original report and our April 9, 1990 letter (ELV-01516).
1 The previous LER stated that the Diesel Generator had been started at least 18 times without failures or problems. The number of tests was determined by counting Diesel Generator tests regardless of whether or not the test constituted a valid test in accordance with Regulatory Guide 1.108, however, only valid failures were considered in reaching the conclusion that there had been no failures or problems. This revision to the LER reflects the results of val.id tests +since the M 206 1990 event 1

V0GTLE ELECTRIC GENERATING PLANT LICENSEE EVENT REPORT 1
Loss OF 0FFt1TE POWER LEADS To SITE AREA EMERCENcY Inaccordancewith10CFR50.73,GeorgiaPowerCompany(GPC)herebysubmitsthe enclosed revised report related to an event which occurred on March 20, 1990, This revision is necessary to clarify the information related to the number of successful diesel generator starts as discussed in the original LER dated April 19, 1990 and our earlier letter (ELV-01516) dated April 9,1990 and to update j
O, the status of corrective. actions.
The letter of April 9 stated.that Diesel Generator 1A had been started 18 times and that Diesel Generator 1B had been started 19 times since March 20, 1990. The LER dated A)ril 19 inadvertently stated " Subsequent to this test program, DG1A and DG1B inve been started at-1 east 18 times each and no failures or problems have occurred during any of these starts". The statement made in the LER and in the April 9 letter did not consider troubleshooting problems associated with the restarting of Diesel Generator 18, which was out of service for maintenance at the time of the event.
The report should have stated " Subsequent to the event..."rather than
" Subsequent to this test program..." with this change the LER is consistent with the letter of April 9 and the presentation made by GPC to the NRC in Atlanta on the same day.
in order tu correct' the tER"and'to provide more nefut and'up to dute -
4 information the LER has been revised to state the number of valid diesel generator tests in accordance with Regulatory Guide 1.108 rather than the number of successful starts since the event. The number of valid tests was established by reviewing diesel generator testing data from March 21 inrough June 7, 1990.
