Dear Mr. Kruesi:
In conformance with paragraph 50.55(e) of 10 CFR 50, this is submitted as an interim report of a possible design deficiency which was initially reported to AEC-DRO Inspector W. S. Little on December 3, 1973. The failure was in connector G9 of elec-trical penetration EF of Browns Ferry Nuclear Plant unit 2, the worst damage occurring at two pins connected to the 480-volt single phase powcr outlet to the control rod drive service platform.
Personnel at the construction site have prepared a report describing the failure and that report is being reviewed by engineers in our Division of Engineering Design. Further inves-tigation is required to determine conclusive'ty the cause of failure.
We expect to submit a final report by February 3,1974.
Very truly yours, J. E. Gilleland Assistant to the Manager of Power 1
