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.

l 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 NRC by senior Licensee officials regarding the reliability of the Diesel Generators (DGs). The pertinent events involved in this matter are described below.

O On March 20, 1990, during a refueling outage at VEGP Unit 1, GPC declared a Site Area Emergency (SAE) when offsite power was lost concurrent with the failure of the only. Unit 1 DG that was available (1A). The other Unit 1 DG (1B) was unavailable due to maintenance activities. .

The NRC immediately responded to the SAE at the VEGP site with an Augmented Inspection Team (AIT). The NRC effort was upgraded to an Incident Investigation Team (IIT) on March 23, 1990. The IIT was composed of NRC Headquarters technical staff and industry personnel. The results of this investigation are documented in 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."

On March 23, 1990, the NRC issued a Confirmation of Action Letter (CAL) to GPC that, among other things, confirmed that GPC had agreed not to return VEGP Unit 1 to criticality until the Regional Administrator was satisfied that appropriate corrective actions had been taken, and that the plant could safely return to power operations.

On April 9, 1990, GPC made a presentation to the NRC in the Region II offices in support of GPC's request to return VEGP Unit 1 to power operations. As part of this presentation, GPC provided information on DG starts in response to a specific NRC

request that GPC address DG reliability in its April 9 presentation. GPC submitted a written summary of its April 9

presentation in an April 9, 1990 letter, "Vogtle Electric Generating Plant Confirmation of Action Letter."

l .

On April 12, 1990, the NRC formally granted permission for VEGP j' Unit 1 to return to criticality and resume power operations. j i

On April 19, 1990, pursuant to 10 CFR 50.73, GPC submitted l

! Licensee Event Report (LER) 50-424/90-06, " Loss of Offsite Power

! Leads to Site Area Emergency."

i a

~

On June 29, 1990, GPC submitted a revised LER, 50-424/90-06-01.

2 The purpose of the submittal was to clarify information related 4

to successful DG starts that were discussed in the April.9, 1990 letter and the April 19, 1990 LER, and to update the status of j corrective actions in the original LER.

1 From August 6 through August 17, 1990, the NRC conducted a Special Team Inspection at VEGP, as a result of NRC concerns i

3 about, and allegations related to, VEGP operational activities, i

This inspection examined the technical validity and safety

! significance of the allegations, but did not investigate alleged wrongdoing. The Special Team informed GPC that the June 29, 1990 submittal failed to address the April 9, 1990 data and requested l l that GPC clarify-DG starts reported on April 9, 1990. Results of i

this inspection are documented, in part, in NRC Inspection Report 1

No. 50-424,425/90-19, Supplement 1, dated November 1, 1991.

On August 30, 1990, GPC submitted a letter, " Clarification of l Response to Confirmation of Action Letter." The purpose of the submittal was to clarify the diesel start information that was l addressed in the April 9, 1990 submittal.

III The NRC has reviewed the evidence associated with these events, I 1

submittals, and representations to the NRC. Specifically, the NRC reviewed information gathered as part of the OI investigation, information gathered during the IIT, NUREG-1410, Supplement 1 of NRC Inspection Report 90-19, discovery responses in the Vogtle operating license amendment proceeding (Docket Nos. 50-424 OLA-3, 50-425 OLA-3), and other related information.

ammmmmmmmmmy Mr. McCoy was actively involved in the preparation of the June 29, 1990 cover letter and reviewed it prior to forwarding it to the Senior Vice President - Nuclear Operations for signature and issuance. The June 29, 1990 cover letter stated that its purpose was, in part, to clarify information provided to the NRC on April 9, 1990. Ng Mr. McCoy committed during the August 17, 1990 meeting with the NRC Special Inspection Team to provide clarification to the NRC regarding the April 9, 1990 letter.
