occurred during any of these starts. The LER refers to both diesel generators as "having been started at least 18 tames each O and no failures or problems have occurred during any of these starts."

NRC's Operational Safety Inspection team which reviewed this 4

matter in August, 1990, unit control logs and shift supervisor logs were the source of the data used in developing the numbers "18" and "19" found in the coAR and the original LER. The i

numbers originally were included in a transparency developed by vogtle plant personnel; this transparency was included in handouts at an April 9, 1990 asating with the NRC in Atlanta, Georgia. The COAR, written the same day as the meeting with NRC representatives in Atlanta, adopted the "18" and *19" nuabars.

The LER, written later, also was predicated upon the '18" and "19" start count. statements in the custody of the Operational Safety Inspection team confirm that both documents basically used the information developed for the April 9 transparency.

In addition, successive dEAft revisions of the LER have been reviewed by GPC. A version of the LER prepared by the site, dated April 17, 1990, identified "several starts" rather than An specifying a number of starts (Exhibit 3, p. 6 of draft' LER) .

attendce at the plant Review Board stated that a specific number should be used and the next draft version of the LER stated that the number was "more than 20 times" (Exhibit 4, p. 6). The "more l than 20 times" phraseology was provided to corporate  !

representatives in Birmingham (Exhibit !). These l representatives, with knowledge of the is und 19 numbers used in O the transparency on April 9, questionedMon each" language provided by the site.

LER draf ts confirm other ef forts by corporate representatives to verify other information and assure the accuracy of the LER l (Exhibit 6). '

Additional diesel generator starts had occurred subser[uent l l

to April 9, 1990 (the date of the GPC meeting in Atlanta VLth NRC

and the final April'19th LER wording stated '

l representatives),l that a i engine had been started "at least la times i

Company's efforts to troubleshoot and test the operability of the diesel generators and believed that the NRC had all relevant information on the diesel generators' operability and i reliability. Nevertheless,'either before or concurrent with the i 3 The wording was reviewed by corporate and site representatives in a telephone conference call late on April 19, 1990. Although Mr. Hairston was not a participant in that call, i

l

' he had every reason to believe the final draft LER presented to i

him after the call was accurate and complete.
