UNIT SHUTDOWN AN0 POWER REDUCTIONS EXPLANATION SHEET DOCKET N0.50-338 REPORT MONTH Jan. UNIT NAME North Anna YEAR 1980 DATE 2-1-80 COMPLETED BY A. G. Neufer 9 L

80-01 thru 80-03 (A) (0.0*) Turbine generator was not in service at the k time of the above reactor shutdowns due to low power physics testing I which are required after refueling. Technical Specifications require Il the reactor to be shut down when less than 3 reactor coolant pumps are S operable. 7

,t 80-04 (G) Voltage spike caused during perfomance testing of PT-1447 first j stage turbine pressure defeating the block of P-7 (at power trips) the }

reactor tripped because the turbine was not latched. m k

80-05 (00*) This trip was plannned as part of low power physics testing.  ;

80-07 (H*) Small mesh strainer are temporarially installed in the suction l of the condenser pumps as part of the post maintenance clean up f e f fort. The B pump was out of service and one pump strainer was being ';

cleaned when the remaining strainer clogged up causing a trip of the  :.

feedwater pumps. This caused steam generator water level to go low l causing the reactor trip.
