SUMMARY

OF OPERATING EXPERIENCE AUGUST 1984 Indian Point Unit'3 was synchronized to the bus for a total of 653.17

' hours producing a gross generation of 598,390 MWH for this reporting

. period

'As a result of a feedwater transient'a unit trip occurred on August 22 oat 2122 hours0.0246 days <br />0.589 hours <br />0.00351 weeks <br />8.07421e-4 months <br /> due to a hi-hi" steam generator level. The investigation revealed that a leak in a control oil hose caused the perturbation in the

- main boiler. feed pump control oil system. The' unit was returned to service on August 23 at 1937 hours0.0224 days <br />0.538 hours <br />0.0032 weeks <br />7.370285e-4 months <br />.
