17 801206 F 0 A/il NA 80-040/3L RB CRDRVE During steady-state 100% power opera-tions, CEA #31 dropped to zero steps from 180 steps. This resulted in operations, per spec ~s., at a reduced power level of 70%. There were no component failures found. The C.E.A.

was realigned at 180 steps and 100% ,

power operation was resumed. It is unknown why the CEA dropped, previous history and performance since has been normal.

Summary: The unit operated at or near 100% of rated thermal power throughout the reporting period except for the power reduction on the 6th.
