NC U. S. Nuclear Regulatory Commission Operations Branch Division of Reactor Safety Region II - Suite 2900 101 Marietta Street, FW Atlanta, Georgia 30323 Attention: Caudio A. Julian Gentlemen Georgia Power Company is supplying the information in this letter and its attachments as esquested by the NRC at the GPC -
NRC Region II meeting of December 1987.
As discussed at the meeting, Gecrgia Power Company wall be applying for dual unit licenses for its operators licensed on unit i at ths Vogtle Electric Generating Plant in the fall of 1988.
Attachment I contains an overview of the formal training program to support the application for dual unit licenses.
Attachment II contains tne differences between VEGP units 1 and 2 which have been approved for inclusion in a
differences training program for licensed operators.
Due to the limited number of differences and the nintaal operational effect of the differences.
Georgia Power Company will request a
waiver of both the written and operational (simulator and plant walkthroagh) exastnations for those licensed operators who complete the training program.

P roced u res, Primarily Abnormal and Emergency Operating Procedures Limitad operational differences should exist in the EOPs and AOPs.
These differences may include:
1.
A reference in the remote shutdown AOP regarding the remote operation of the unit 2 DG fuel oil transfer pumps.
2.
Reference in the EOPs to the sequencer reset pushbutton.
Conten1 Ecss Damian and Instrument Lncationa Control Room Layout The Unit 2 Main Control Board (QMCB) is a rotated image of the Unit 1 Main Control Board.
On sections A, B, and C of the Main Control Board the left-right relationship for all the controls and displays is identical.
This identical relationship for the A,
B, and C section includes the board layout and labeling.
The Control Room Design Review will note any differences this summer.
None are planned or expected.
The one exception to identical layout on the Main Control Board is the D section.
The D section was a backfit after the control room design was completed and floor space did not allow an identical arrangement.
Section D contains the same equipment on both units (RVLIS, PSMS, and Main Steam Bypass Isolation Valves).
Section D
is on the left end of section A on unit 1 and to the right of section B on unit 2.
This will require looking lef' on unit 1 and right on unit 2 to verify that the Main Steam Bypass Isolation Valves are shut on a Main Steam Isolation.
There should be no impact on routine unit operation.
The rest of the Unit 2 Control Boards appear as if the Unit 1
Boards were moved west.
Their appearance on unit 2 will be the on unit 1 if you are standing in front of them.
The s ame as Electrical Auxiliary Board (GEAB) will appear somewhat different from the center of the control room.
In unit 1 it is over the right shoulder and in unit 2 it will be over the left shoulder.
This will require a slightly different scanning pattern during immediate operator action in the EOPs but should have no impact on unit oseration.
The high voltage section of the QEAB is different to reflect the differences in the switchyards but the Unit 2 inplant distribution systems will appear identical Unit 1.
The common distribution system is on the Unit 1 QEAB.
The control boards will be different to the extent that most common equipment is located on unit one.
The Process and Effluent Radiation Monitoring System Panel (PERMS) non-safety related communications console for unit 2 will be at the west end of the QIAB instead of the east end of the Relay Panel as it is on unit 1. See AX5D52-A02 ( Attached ) for the control room layout.

4 Control Room Wall I
A security wall was erected through the center of the common control room to separate unit 1 from unit 2 when unit 1 security went into effect.
Original plans were for this wall to be removed when unit 2 security went into effect.
Current plans are to leave most of the wall to reduce
- cost, provide unit separation, and reduce inter-unit noise.
The wall will be open i
on the Shift Supervisors station, near the south door, and behind the QPCP, Plant Computers The plant computer (PROTEUS and ERF) terminals will be in mirror image locations.
The PROTEUS computer will be identical in function.
The IRT computer will be identical except that the common radiation monitors and weather data will be displayed only on unit 1.
Hanned Differences Valve and Instrument Labeling Program The valves and instruments located at the Vogtle Electric Generating Plant are labeled with unique labels that indicate unit number, system number. valve or instrument number, the name of the valve or instrument indicating its purpose, the train if appropriate, and any special notes about the component.
Unit 1 has white rectangular (3" X 4") labels and unit 2 has round (4"
diameter) blue labels.
Operations Procedure Binders The unit specifio procedure binders (system operating procedures.
lineup procedures, operations surveillance procedures, etc.) are marked indicating which unit they belong to.
Unit 1 procedures are marked with a large 1 and unit 2 procedures are marked with a large 2.
