NARRATIVE

SUMMARY

OF MONTHLY OPERATING EXPERIENCE - AUGUST, 1984 August 1 The station was in operational mode 1 with reactor power a through nominal 100%. The reactor coolant system was at normal August 22 operating temperature and pressure.

August 23 At 0606 hours0.00701 days <br />0.168 hours <br />0.001 weeks <br />2.30583e-4 months <br />, the fluid pressure in the main turbine's electro-hydraulic control system dropped to 1200 psig, down from a normal operating range of 1800 - 2100 psig. The second EHC pump started and returned system pressure to normal, but did not cycla as it should have. A reduction in reactor power was begun ir anticipation of an EH system failure. Power was dropped to 40% and held.

Troubleshooting of the system revealed that a flow restricting l orifice to the EH system clean up filters had blown out, thereby allowing an inordinate amount of flow to be recirculated tu the

! EH reservoir. The filters were isolated and the system returned

! to normal operation. A reactor power increase was started at 0823 hours0.00953 days <br />0.229 hours <br />0.00136 weeks <br />3.131515e-4 months <br />. 100% reactor power was reached at 2400 hours0.0278 days <br />0.667 hours <br />0.00397 weeks <br />9.132e-4 months <br />.

August 24 The station was in operational mode 1 with reactor power a through nominal 1004. The reactor coolant system was at normal operating August 31 temperature and pressure.
