SALEM UNIT #1

.January,* 1978. *.

i-1 *With the plant operating at -88% of. capacity, .the heater drain pumps were cycled as. pa'rt of .a program to clean the Feed . and ...

Condensate System.. Power was t;:hen reduced to *.70% *to cleari all condensate pump suction strainers.

At 0825 unit output *was returned to full load of 1140 Mwe gross. The unit operated at full load until 1-4.

1-4 With the unit at full power, .Circulating-Water System problems forced a load reduction to 50% power. Several minutes after the load reduction, #12 Steam Generator Feed* Pump tripped; followed by -a trip of #11 Steam Generator Feed.* Pump. A Reactor Turbine Trip occurred from_50% power caused by low condenser*

vacuum.

At 0350 the reactor was taken critical and the unit was syn-chronized at 0625.

1-5 At 0449 the unit output was.returned *to full load.

At 2128 load was reduced to 70% to clean *condensate pump strainers.

1-6 At 1210.unit output was returned to full load.

1-7 At 2145 load was.reduceq to cycle heater drain PumPS and clean condensate pump suction strainers.

  • 1-8 .At 0827 unit output was returned to full load .

.1-9 .The unit remained at full load esse~tially all.day". except for

.a short period at 70% due to circulating water problems.

The.outage lasted*until 1-16.

1-16 The reactor was*taken critical at 0828 and the unit was synchronized at 2206.

? 1-17 At 0713 the unit tripped from 150 MWe gross due to high-high level in #13 *Steam Generator...

  • This stemmed from frozen feeler lines on a feedwater heater drainage valve that operated .a

.bypass valve which caused.an unstable feedwater condition. *The operator attempted to manually control_feedwater to avoid a low.;..low level.. trip. The transient led to a .high-high level trip.

The reactor was taken critical at 0852 and the unit was synchronized at 1331.

1-18. At 0630the unit-output was returned to full load:

At 1145 the. load was reduced to 70% to clean condensate pump suction strainers and was* returned to full load at 2200. *The unit remained at full power until 1-23.

1-23 At 0915 a Reactor Turbine Trip occurred caused by a malfunction of the E-H Control System.

At 1330 A Reactor Coolant System cooldown*was started to repair leaking #12 and #13.Steam Generatoz;, steam* side *manways.

At 1759 a Safety*Injection occurred during cooldown at-about 200,psigsteam generator pressure on.a high *differential pres-sure between steam generators. (Ref.* L.E.R. No. 78-04)

The outage lasted till .1-29.
