NRC MONTHLY OPERATING REPORT

SUMMARY

OF OPERATIONS WATERFORD 3 OCTOBER 1985

.The unit started the month at approximately 20% power and reached 100% power on October 1.

On October 2 at 912, at 100% power, a reactor trip occurred on low steam generator level resulting from a feedwater pump trip due to a failure in the feedwater control system. On October 2, at 1358, the reactor achieved criticality. On October 2 at 2035 a reactor trip occurred on high steam generator level. The unit remained shutdown to replace reactor coolant pump seals. On October 10 at 1330, the reactor achieved criticality and at 1637'a reactor trip occurred on high steam generator level. On October 10 at-1934 the reactor returned to criticality and at 2211 the generator was back on line.

I On October 28 at 1920, at 100% power, a reactor trip occurred resulting from an auxiliary high pressurizer pressure trip generated by the core protection calculators..This trip was a result of a steam leak which caused water from the fire protection deluge system to enter the feedwater pump control system catasing a feedwater pump trip. On October 29 at 1020, the reactor achieved criticality and on Octobe r 30 at 309, the generator was back on line. On October 31, the unit reached 100% power.
