NARRATIVE ShMMARY OF MONTHLY OPERATING EXPERIENCE - SEPTEMBER, 1984 I

1 S;ptember 1-J .The station was in operational mode.1 with reactor power a through nominal 100%. The reactor coolant system was at normal S:ptember 6 . operating ~ temperature and pressure. .,

'Saptember 7- .The 1A heater drain pump was started at 1310 hours0.0152 days <br />0.364 hours <br />0.00217 weeks <br />4.98455e-4 months <br /> following

-repacking. The pump tripped at 1429 hours0.0165 days <br />0.397 hours <br />0.00236 weeks <br />5.437345e-4 months <br /> on low heater drain tank level due to tank low level control valve, LCV-SD-106B, failing open. -A ruptured diaphragm was the cause. The loss

' of the heater drain . pump caused the IB main feedwater pump to begin vibrating. Tho'feedwater pump was shutdown at 1450 hours0.0168 days <br />0.403 hours <br />0.0024 weeks <br />5.51725e-4 months <br /> and reactor power was stabilized at 58%. 'The pump was restarted at 1925 hours0.0223 days <br />0.535 hours <br />0.00318 weeks <br />7.324625e-4 months <br /> and reactor. power was increased to 100%.

. September 8 Permission was received at 0140 hours0.00162 days <br />0.0389 hours <br />2.314815e-4 weeks <br />5.327e-5 months <br /> from the DLCo. system operator to' reduce station load to 60% in order to remove the L 'lB main.feedwater pump from service. 'A seal water line to the

-pump was leaking. Repairs were made and the pump was restarted at 1010 hours0.0117 days <br />0.281 hours <br />0.00167 weeks <br />3.84305e-4 months <br />. Station load was.being increased when the seal water line to the 1B main feedwater pump again began leaking.

Station load was reduced to 60% reactor power. FW-P-1B was shutdown for repairs due to continued high vibration.

September 9 Repairs were being made to FW-P-18. The pump was started and I through shutdown.soveral times during the troubleshooting. The repairs l September 16 were completed at approximately 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on the 16th and the pump was started at 1206 hours0.014 days <br />0.335 hours <br />0.00199 weeks <br />4.58883e-4 months <br />. Reactor power ascension began ,

at 1252 with holds at 5% increments for vibration readings on l

! the IB main feedwater pump. Reactor power reached 100% at approximately 1830 hours0.0212 days <br />0.508 hours <br />0.00303 weeks <br />6.96315e-4 months <br />.

l September 17 The station was in operational mode 1 with reactor power a through nominal 100%.

September 28 -

September 29 The station experienced a 50 MWo load rejection at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> when rehoater steam supply valves FCV-MS-100A and C tripped shut. The valves were opened at 0938 hours0.0109 days <br />0.261 hours <br />0.00155 weeks <br />3.56909e-4 months <br /> using the local nanual override. Reactor power was increased to 100%.

September 30 The station was in operational modo 1 with reactor power a nominal'100%. .
