SUMMARY

OF SHUTDOWN EXPERIENCE FOR OCTOBER 1978 10-2-78 The plant was taken off-line in order to permit repairs to leaking CRDM Seals. Two seals were replaced. In addition, the position indication on one CRDM was re-zeroed, oil was added to one Primary Coolant Pump (P-50C) and changed in another Primary Coolant Pump (P-50A). The outage lasted 123.4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

10-17-78 Because of a Feedwater Pump trip when attempting to change the steam supply from high pressure to low pressure steam, the Reactor tripped on low Steam Generator water level.

The plant was off-line for 9.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
