Dear Mr. Grier:

On February 26, 1980, the NRC resident inspector at Callaway Site was informed by Union Electric of deficiencies in electrical penetration assemblies furnished by Bunker Ramo Corporation to the Callaway site.

Further investigation indicated these deficiencies to be generic in nature and were subsequently reported to Region I on March 24, 1980 via telecon between McGaughey, NRC and Seiken, SNUPPS. It was further indicated that this matter would be described in a generic Significant Deficiency Report to be issued by April 30, 1980 by SNUPPS applicable to all SNUPPS units. A further extension to May 7th was requested of and agreed to by Mr. McGaughey on April 30th.

Enclosed with this letter is a report of the defective penetration assemblies. This report provides a chronology of events associated with discovery of the described deficiencies; summarizes safety impli-cations associated therewith and outlines a plan of follow-up correc-tive actions initiated and/or planried. This plan will provide for test verification of all questionable or suspect penetration wiring sufficient to assure performance acceptability. \

SLNRC 80-22 Page Two It should be noted that the enclosed report is being treated as a final submittal under 10CFR50.55(e) definitions. The corrective action plan outlined in the enclosure will be monitored by Callaway and Wolf Creek site QA persannel. In the event additional actions are required or should complications result in the implementation phases, a supplemen-tal report will be prepared and forwarded to NRC. In the interim, fur-
