Docket No.: 50-424 APPLICANT:
Georgia Power Company FACILITY:
Vogtle, Unit 1
SUBJECT:
SUMMARY
OF MEETING HELD ON APRIL 28, 1987 TO DISCUSS V0GTLE STARTUP HISTORY-The staff met with the licensee at the Vogtle site on April 28, 1987, to discuss the Vogtle startup history. The visit was a routine post-full power licensing visit but the staff was particularly interested in the licensee's discussion of the relatively high number of reactor trips and engineered safety feature (ESF) actuations. Participants are listed in Enclosure 1.
The licensee's slide presentation is included as Enclosure 2.
At the time of the meeting, the unit was performing power ascension testing at the 75% power plateau. Convr.ercial operation is estimated for late May.
The licensee discussed its corrective actions to recent secruity problems.
These actions included establishing a security task force, daily management security meetings, added engineering support, and enhanced training for the security staff and all site employees. The licensee stated that daily security alarms have decreased to about 400 which is down from a peak of 1100.
While this progress represents a significant reduction, the licensee's goal is no more than 200 security alarms per day. The licensee indicated that lessons learned during implementation of the Unit 1 security system will be factored into the Unit 2 security program, and security will be included in the Unit 2 Readiness Review effort.
The licensee discussed problem areas and highlights of Each of the four phases of the startup testing program (fuel load, precritical, low power physics, and power ascension). During low power physics testing, the unit experienced a trip on high positive rate due to an overly conservative trip setting from Westinghouse to which the licensee had added additional margin. After this trip, the licensee incorporated revised Westinghouse data which has prevented recurrence of this type of trip.
The licensee is approximately 60% complete with the power ascension testing.
Between March 20 and April 11, the unit has experienced 8 reactor trips on 10-10 steam generator level. Besides some limited personnel errors (operators and technicians), the cause of these trips has been attributed to lack of plant-specific setpoints and needing additional tuning of the steam generator level and steam dump controllers. The utility indicated its belief that these items have been corrected. The lessons learned in tuning the Unit I controllers will be applied to Unit 2 startup.
M F
. As of April 28, the utility stated that it had received 16 ESF actuations separate from a reactor trip.* The most prevalent types of ESF actuations are main feedwater isolation and control room isolation. Each control room isolation has been caused by failure high of a control room inlet radiation monitor. The utility has had limited success in resolving the continuing recurrence of actuation of the radiation monitor.
Prior to the meeting, the resident inspectors had informed the licensee that it should report control room isolations caused by actuation of a chlorine detector. At the meeting, the staff emphasized its position that isolation of the control room irrespective of the initiating event is considered an ESF actuation and should be reported as such. The licensee agreed to abide by the staff's position.
In closing, the staff comended the licensee for a thorough, well-prepared presentation. While interface with vendors and other utilities possibly should have occurred sooner on some recurring events, the staff concluded that the licensee appeared to be taking adequate corrective actions to address problems experienced during the Vogtle Unit I startup program.
he b Melanie A. Miller, Project Manager Project Directorate II-3 Division of Reactor Projects I/II
Enclosures:
As stated cc: See next page This number differs from the NRC number in that the staff also includes a fuel handling building isolation and 3 control room isolations initiated by a chlorine detector as ESF actuations.

. As' of April 28, the utility stated that it had received 15 ESF actuations separate from a reactor. trip.* The most prevalent types'of-ESF actuations are
- main feedwater isolation and control room isolation.' Each control room
-isolation'has been' caused by failure high.of a~ control. room inlet radiation monitor. The utility has had limited success in resolving the continuing-recurrence of actuation of the radiation monitor.
Prior to the meeting, the resident inspectors had informed the licensee that it should report control room isolations caused by actuation of a chlorine detector. 'At the meeting,-the staff emphasized its position that isolation of the control room irrespective of the initiating event is considered an ESF actuation and should be reported as such. The. licensee agreed to abide by the staff's position.
In closing,- the staff consended the licensee for a' thorough, well-prepared presentation. While ~ interface with vendors and other utilities possibly should have occurred sooner on some recurring events, the staff concluded that the licensee appeared to be taking adequate corrective actions to address problems experienced during the Vogtle Unit 1 startup program.
\\sh Melanie A. Miller, Project Manager Project Directorate II-3 Division of Reactor Projects I/II
Enclosures:
As stated-cc: -See next page
--This numoer differs from the NRC number in that the staff also includes a fuel handling building isolation and 3 control. room isolations initiated by a-chlorine detector as ESF actuations.
