ROGERS 82-01 (G) (5) On January 7, 1982 with the Unit at 100% power, power range detector N-44 drifted low and was declared inoperable. The cause for exceeding the initial 12 hour surveillance was due to improper input of data to the plant computer. The faulty power ragge detector is scheduled to be replaced during the refualink outage. Personnel have been mai.e aware of the 12 hour QPTR surveillance requirement and a more rigorous sc hedule has been set up to implement the surveillance. c f e I l l t
