[l(p Ceportment of Chemical and Nuclear Engineering October 10, 1986 Mr. Thomas Elsasser U.S.
Nuclear Regulatory Commission Region 1 631 Park Avenue King of Prussia, PA 19406
Dear Mr. Elsasser:
This letter is in response to a " Reportable Occurrence" telephoned to you on September 30, 1986.
A low battery voltage in the thermocouple circuit caused a malfunction of the fuel temperature readout which was observed quickly as part of the normal operating procedure instrument check.
Reoccurrence of this type of malfunction has been minimized by implementing a battery replacement procedure using a six month replacement interval.
This replacement scheme is now an item in the standard survellance procedures.
Sincerely, h & $c f-i t-MLR:ga Marvin L.
