Dear Mr. Hovey:
PLynch The NRC staff has reviewed your Recovery Operations Plan Change Request No. 7, dated June 15,1981 (LL2-80-0160). The change request proposed that the number of air temperature indicators required to be operable at each of three elevations be modified from two to one to allow for esisting system redundancy.
You stated that this change allows more flexibility in scheduli6g7 maintenance in the event of indicator failure, and does not affect plant safety because the redundant temperature indicators on the same level do not vary more than two degrees.
Presently Surveillance Requirement 4.6.i.S requires two temperature indicators at each elevation. After performing a general review of the data points for the indicators, the staff has confirmed that only very minor temperature fluctuations occur between both detectors on the same elevation. Therefore, we have concluded that one detector reading per elevation will provide an adequate indication of temperature at that elevation with the seccnd instru-ment available as a spare. We have therefore approved the proposed change in Surveillance Requirement 4.6.1.5 to indicate that only one temperature indicator is required at each elevation.
A copy of Change No. 6 to the Recovery Operr. tion Plan is attached.
Sincerely, Bernard J. Snyder, Program Director THI Program Office Office of Nuclear Reactor Regulation
