Reference:

Vogtle Electric Generating Plant - Unit 2; 5 425 I Cable Separation Within Panels Letter GN-1403, dated 10/6/87 On September 9, 1987, Mr. R. E. Folker, Vogtle Project Quality Assurance Engineer, notified Mr. M. V. Sinkule of the USNRC-Region

, II of a potentially reportable condition involving the electrical separation criteria specified in Construction Specification X3AR01.

In subsequent correspondence with the NRC, Georgia Power Company ,

indicated that a final report on this issue was expected to be submitted by December 1, 1987. However, after reviewing the results of a detailed study comparing the test report performed by Wyle Labs on electrical separation, the construction specification, design criteria, and the FSAR; Georgia Power Company (GPC) decided to perform further tests on different configurations to extend the results of the original tests. These tests wre designed to j the same criteria as the original tests and were performed by the '

same laboratory.

This second test of electrical separation requirements has been performed by Wyle Labs. The preliminary results are being reviewed and are very positive. However, because of the change in plan, a final report on this issue will not be available for submittal by December 1 .987, as expected. GPC currently anticipates completing the i piew of the test report, performing a plant walkdown if required, anc submitting the final report prior to March 1, 1988.

This correspondence contains no proprietary information and may be placed in the NRC Public Document Room.
