I Georgia Power Company (Licensee) is the holder of Facility License Nos. NPF-68, and NPF-81 (Licenses) issued by the Nuclear Regulatory Commission (NRC or Commission) pursuant to 10 CFR Part 50. The Licenses authorize the operation of the Vogtle Electric Generating Plant (VEGP) Units 1 and 2, in accordance with conditions specified therein.

F0IA-On December 17, 1993, an investigation of licensed activities was completed by the NRC's Office of Investigations (OI) at Licensee's VEGP facility. The investigation was initiated in response to information received in June 1990 by NRC Region II alleging, in part, that material false statements were made to the ::.~.0 by senior Licensee of ficials regarding the reliability of the Diesel Generators (DGs). The pertinent events involved in this matter are described below, e

concurrent with the failure of the only Unit 1 DG that was

The NRC immediately responded to the SAE at the VEGP site with an

! Augmented Inspection Team (AIT). The NRC effort was upgraded to I an Incident Investigation Team (IIT) on March 23, 1990. The IIT l

4 was composed of NRC Headquarters technical stafr and industry 1

personnel. The results of this investigation are documented in l!

NUREG-1410, " Loss of Vital AC Power and the Residual Heat Removal System During Mid-Loop Operations at Vogtle Unit 1 on March 20, 1990."

l d i i 1 On March 23, 1990, the NRC issued a Confirmation of Action Letter l (CAL) to GPC that, among other things, confirmed that GPC had i

agreed not to return VEGP Unit 1 to criticality until the i Regional Administrator was satisfied that appropriate corrective  ;

actions had been taken, and that the plant could safely return to power operations. l On April 9, 1990, GPC made a presentation tc the NRC in the Region II offices in support of GPC's request to return VEGP l Unit 1.to power operations. As part of this presentation, GPC provided information on DG starts in response to a specific NRC

l From August 6 through August 17, 1990, the NRC conducted a i

Special Team Inspection at VEGP, as a result of NRC concerns i about, and allegations related to, VEGP operational activities. l This inspection examined the technical validity and safety significance of the allegations, but did not investigate alleged 5

wrongdoing. The Special Team informed GPC that the June 29, 1990 submittal failed to address the April 9, 1990 data and requested that GPC clarify DG starts reported on April 9, 1990. Results of 1

l Prior to rPC briefing the Regional Administrator, Region II, on VEGP's readiness for restart, the NRC asked GPC to address DG reliability as part of its restart presentation on April 9, 1990.

For that presentation, Mr. Bockhold was personally involved in i l

the preparation of data regcrding DG laliability and tasked the Unit Superintendent with collecting the number of successful DG 7

In fact, Mr. Bockhold stated no criteria for successful starts, a terr. not formally defined, when he directed the Unit Superintendent t gather successful DG starts.,

-- l The Senior Vice President - Nuclear Operations I

also stated that he thought the April 19, 1990 data had been checked.

I On May 2, 1990, Mr. Bockhold was given a lirt of DG starts that l

showed that the start counts reported in the April 9, 1990 presentation, the April 9, 1990 CAL response letter, and the April 19, 1990 LER were incorrect. Mr. Bockhold agreed that the LER needed to be revised to reflect the correct number of starts.

Mr. Bockhold also agreed that the April 9, 1990 letter needed to be corrected because he asked and was informed that th' **ril 9 1990 error was cifferent than the April 19, 1990 error. It was also agreed that uniferm language would be used to cortect both documents, i

,5 During the NRC's Special Tean Inspection exit interview on August 17, 1990, GPC was specifically notified by the NRC that the revised LER did not adequately clarify the DG start information contained in the April 9, 1990 letter, and NRC reauested GPC to provide clarification of this submittal. GPC forwarded a submittal to the NRC on August 30, 1990 regarding the April 9, 1990 letter. A draft of the August 30, 1990 letter, sent to the site for review, suggested that one of the reasons for the error in the April 9, 1990 letter was

" confusion in the distinction between a successful start and a valid test" by the individuals who prepared the DG start information for the April 9, 1990 letter. During an August 29, 1990 Plant Review Board (PRB) meeting which, amc.cg other things, reviewed the proposed August 30, 1990 submittal to the NRC, the VEGP Manager - Technical Support raised concerns about the accuracy of that statement. Mr. Bockhold admitted to the PRB that the Unit Superintendent (who origi nally collected the DG start data at Mr. Bockhold's direction) was not confused about the distinction between successful starts and valid tests when the start data was collected for the April 9, 1990 letter, but stated that the sentence was not in error because other people ,

l were confused. Mr. Bockhold acknowledged that there was l l

I I

-u- i l

confusion among individuals after April 9, 1990, but admitted l that the Unit Superintendent was not confused when he developed the information.[
