Gentlemen:

I I

i Supplement 4 to the Vogtle Safety Evaluation Report,Section I

7.J.3.8 concluded that confirmatory item 26 was resolved for Unit i

l 1.

This confirmatory item concerned the redesign of the reset / override circuitry for several instrument channels wh*ch j

provide isolation signals so that each reset / override switch would affeet only a single instrument channel.

l l

GPC has reviewed the Unit 2 design and concluded that it is the 9

same as the Unit i

design accepted in Supplement 4.

The I

l installation of this circuity has also been completed in Unit 2.

This should allow the resolution of confirmatory item 36 for

{

Unit 2.

If your staff requires any additional information, please do not hesitate to contact me.

l Sincerely, i

\\
