February 14, 1980 M r. James G. Keppler, Regional Director U. S. Nuclear Regulatory Commission Region III 799 Roosevelt Road Glen Ellyn, Illinois 60137 Re: NRC IE Bulletin 79-28, "Possible Malfunction of NAMCO Model EA180 Limit Switches At Elevated Temperatures,"
dated December 7,1979 - Docket No. 50-367
Dear Mr. Kepple r:
This letter is in response to IE Bulletin No. 79-28 dated December 7,1979. We have determined, through correspond-ence with our NSSS vendor and architect / engineer, that NAMCO Model EA-180 limit switches described in the referenced IE Bulletin have not been and will not be installed on any safety-related equipment located inside or outside containment, including valve position indicating circuitry related to contain-ment isolation valves.
Very truly yours, M
