4 Docket No. 50-352 Attachment to Monthly Operating Report for September, 1987 i

Limerick Generating Station Unit 1 September 1, through September 30, 1987 I.

Narrative Summary of Operating Experience The unit began the report period operating at 23% power following startup from the first refueling outage.

Power ascension continued until September 7, 1987.at 1321 hours0.0153 days 0.367 hours 0.00218 weeks 5.026405e-4 months , when the Reactor Protection System initiated a full reactor scram from 83% power.

The scram resulted from the main turbine stop valves closing following a turbine trip on high water level in the

'C2' moisture separator drain tank.

The cause was attributed'to a moisture separator level.

control supply air problem.

An Unusual Event was declared as' l

a result of the unplanned shutdown.

The scram was reset and i

the Unusual Event terminated at 1345 hours0.0156 days 0.374 hours 0.00222 weeks 5.117725e-4 months and unit start-up operations commenced.

On. September 8, 1987 at 1330 hours0.0154 days 0.369 hours 0.0022 weeks 5.06065e-4 months , the unit achieved criticality.

The unit returned to power operation at 1930 hours0.0223 days 0.536 hours 0.00319 weeks 7.34365e-4 months on September 9, 1987.

On September 19, 1987 with the unit operating at 90% power a

[

full reactor scram occurred when the main turbine tripped due J

to low EHC fluid pressure.

Vibration had caused a weld i

failure on the EHC piping and resulted in the low EHC fluid j

pressure condition.

The weld was repaired, the EHC system j

was returned to service and startup commenced.

On September 20, 1987 the unit achieved criticality and was I

returned to power operation at 2330 hours0.027 days 0.647 hours 0.00385 weeks 8.86565e-4 months on September 21, 1987.

On September 25, 1987, reactor power was reduced to 21% and the turbine was manually tripped at 1353 hours0.0157 days 0.376 hours 0.00224 weeks 5.148165e-4 months to investigate an EHC system leak.

An 0-ring on the #2 Main Turbine Control valve servo was replaced and the unit returned to service at

)

2215 hours0.0256 days 0.615 hours 0.00366 weeks 8.428075e-4 months .

j On September 26, 1987, with the unit operating at 63% power, I

insulation around the #2 Turbine Control valve was discovered smoldering.

The insulation had been oil soaked as a result of the EHC system leak.

Reactor power was reduced to 20% and the turbine was manually tripped at 1833 hours0.0212 days 0.509 hours 0.00303 weeks 6.974565e-4 months .

The insulation was replaced and the unit returned to service September 28 at 0148 hours0.00171 days 0.0411 hours 2.44709e-4 weeks 5.6314e-5 months .

Power ascension continued until excessive vibrations were discovered on EHC piping at the main turbine control valves.

Reactor power was reduced to 83% power and piping vibrations subsided.

The unit continued to operate at this level for
