INCIDENT INVESTIGATION TEAM ARRIVES AT YOGTLE SITE An Incident Investigation Team (IIT) is at the Vogtle site to investigatt * % event of March 20, 1990, which resulted in a Site Area Emersancy when Unit 1 lost offsite and onsite AC power to both vital busses. An Augmented Inspection Team (AIT) has been at the site since March 22, 1990. However, due to the number of past incidents-which have occurred at plants while in shutdown conditions and the potential for regulatory concerns, the agency has decided this most recent event, at Vogtle, warrants the more formal and detailed review of an IIT.

The team is composed of membert from AE0D NRR. Region I, and Region V. Under the provisions of a Memorandum of Agreement with the Institute of Nuclear Power erations (INPO), there is also industry participation on the team, a member from

( 70 and two consultants.

Currently, Unit 2 is operating at full power; Unit 1 is in refueling mode. The team held an entrance briefing with utility management 9:00 a.m. on March 26 and the team leader participated in a press briefing at 12:00 p.m.

This information is current as of 8:00 a.m., March 26, 1990.
