NARRATIVE SUMMAPJ

MONTH: grits t , 1978

The month began with the unit in refueling shutdown. On July 12 at 1900,Zero Power Physics Testing started. Testing was complete on July 16 at0032 and the unit was returned to service. Power reached 40% and was heldfor power escalation testing. Power level reached 75% on July 18 and againheld for testing. Reactor power reached power level cut off on July 20 at1756.

On July 21, power level was decreased to 65% to secure 3A FWPT to resetrelay control. The 3A FWPT was returned to service and started increasingpower at 2024 on July 21.

Power level was held at 94% on July 22 due to powdex resin trap D.P. high.On the same day started decreasing power 3 MW/ minute uue to noise on LPM.Reactor power was increased to 100% on July 24 at 1226.

On July 29 at 2100, commenced reducing reactor power to 15% to perform tur-bine trip test. Generator went off line at 2357. Unit was returned to ser-vice at 0356 on July 30. Reactor reached power level cut off at 1900. On

July 31, reactor reached near rated full power and retained power level forremainder of the month.
