'. MONTHLY OPERATING EXPERIENCE UNIT 1 APRIL 1997 (Continued)

April 14 With the Unit in Mode 2 and the Reactor critical, the Analog Rod Position Indication l

(ARPI) for Control Rod G-3 was declared inoperable at 0001 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months due to reading greater than the Technical Specification limit of 12 steps. In addition, the primary i

detector voltage readings also verified the control rod to be low outside of the 12 step limit. The limiting condition for operation as specified in the Technical

' l Specifications was met because the trippability of the control rod was verified, and the high neutron flux trip setpoint was reduced to 585% of rated thermal power.

Following recalibration of the ARPI for Control Rod G-3, a channel check was performed satisfactorily and Control Rod G-3 was declared c,perable at 0226 hours0.00262 days 0.0628 hours 3.736772e-4 weeks 8.5993e-5 months .

In addition, the primary detector voltage readings also verified the control j

rod to be high outside of the 12 step limit. The limiting condition for operation as specified in the Technical Specifications was met because the control rod position was verified to be within the 12 step limit by using the incore movable detectors.
