NRC MONTHLY OPERATING REPORT OPERATING

SUMMARY

- APRIL 1981 UNIT I The unit began the month at 100% full power and continued t.3:e until 4/8/81. On 4/8/81 the reactor tripped on high RCS pressure,, Jing an attempted runback caused by a false power signal being sent to the ICS. The unit returned to 100% on 4/10/81 and continued normal opera-tion through the end of the month.

A correction was made to the cumulative gross thermal generation of

-1250.31 MWH due to an error in the November 1978 monthly calculations.
