Thomas M. Novak, Assistant Director for Operating Reactors.

Mr. Novak -

~

letter transmitted the "Partial Review, Equipment Evaluation Report by the Office of Nuclear Reactor Regulation," which identified a number of potential environmental qualification of class lE equipment deficiences for Surry Units 1 and 2 and requested review of the impact on safety.

It is not clear, in all cases, what technical bases were used to determine the potential inadequacies identified by the staff in their review.

Therefore, we request a meeting with the staff at your earliest convenience to discuss bases to be used for any reevaluation by the staff and Vepco.

Vepco has reviewed each of the identified potential deficiencies for its impact on safety.

We have concluded, based on our interpretation of the staff's comments, that the environments used in our qualification program are appropriate.

Further, we have concluded that the equipment identified as having potential deficiencies will not result in any unacceptable impact on the safety of Surry Units 1 and 2 operation while the required item by item reevaluation referred to in your March 26, 1981 letter is completed.

Our conclusions are based on the information contained in the following submittals and our review referenced above:

1.

Letter dated October 31, 1980, (Serial No. 887) transmitted the Bulletin 79-0lB 90 Day Review.
