SUMMARY

OF OPERATIONS -

WATERFORD 3 JULY 1985 During the month, power ascension testing was completed as the unit achieved 100% power. The unit started the month at 64% power during a power ascension.

On July 1 at 1844, the unit first achieved 100% power. On July 4 at 0849, at 100% power, a reactor trip occurred on low steam generator water level due to i

a lose of a feedwater pump resulting f rom high vibration. During the unit startup, on July 4 at 2117, at 6% power, a reactor trip occurred on low departure from nucleate boiling ratio (DNBR) resulting from an auxiliary axial shape index (ASI) trip generated by the Core Protection Calculators.

On July 5 at 0545, the generator was back on line. On July 5 at 2120, at 60%

power, a reactor trip occurred on high steam generator water level while controlling water level in manual. On July 6 at 0630, the generator was back on line. On July 7 at 0112, at 90% power, a reactor trip occurred on low steam generator level due to a loss of a feedwater pump while aligning the l condensate polisher system. On July 7 at 1920, the generator was back on line.

On July 14 at 0750, at 100% power, a reactor trip occurred due to an auxiliary high pressurizer pressure trip generated by the Core Protection Calculators as

'j a result of a turbine runback due to a fire in the turbine control system. On July 17 at 1250, the generator was back on line. On July 18 at 0358, at 25%

power, the turbine was manually tripped and the unit was manually shutdown when turbine vibration was discovered. On July 19 at 2353, the unit entered Mode 5 (cold shutdown). The unit remained in this condition through the end of the month to repair turbine generator damage.
