A 02=0812004 12:27 Reactor Building dp restored to less than -0.25 wg. Exited LCO 3.6.4.1 Condition A. (Crow, Barton L.- Control Room Supervisor)
AN 0210812004 12:27 Concur.
(Wheeler, Steven C. - Shift Technical Engineer) 4% 02108/2004 12:30 Completed venting Containment using SBGT to lower pressure to 0.25 psig. (Weiss, Jamie R. - Balance of Plant Operator)
,A 0210812004 13:55 Commenced processing the Waste Collector Tank to WST "B". (Carpenter, Christopher M. - Reactor Building I CT)
AN 0210812004 16:06 Secured transfer. ( Hayes, Martin *Marty" F. - Radwaste)
A 02/0812004 15:02 Completed weekly tour of sewer plant per periodic duties. ( Hayes, Martin "Marty" F. - Radwaste)
A 02/0812004 15:15 Placed SW -P -B, SERVICE WATER PUMP B, in service to raise Service Water header pressure to enhance the backwashing of A Zurn strainer. With 3 SWPs In service header pressure Is 57# which Is within the acceptable range for 3 pump operation at river level of 876.5'. (Weiss, Jamle R. - Balance of Plant Operator)*
- 02108/2004 15:20 A Zurn strainer dip Is 1.0 psld, placed A Zurn strainer to intermitent to secure the continuous backwashlng. It has been determined that service water header pressure rises to 58.5# when the Zurn strainer Is not backwashlng, this pressure is slightly above the 3 pump limit, therefore Service Water Pump B will be secured. (Weiss, Jamle R. -
Balance of Plant Operator)
A 0210812004 15:25 Secured SW-P-B, SERVICE WATER PUMP B, to lower service water header pressure. (Weiss, Jamle R. - Balance of Plant Operator)
A 02/08/2004 15:50 Placed A Zurn strainer control In Continuous operation. (Weiss, Jamie R. - Balance of Plant Operator)
A 0210812004 16:58 Started HV -FAN -(EF-T-1 D), TURBINE BLDG EXHAUST FAN per SOP 2.2.49 to allow dP controller to control building dP. Outside air temperature is above 1OF (currently 35F). HiV-DPIC-840 Is at 56% and turbine building dP Is being maintained at -.25 inches water. Turbine building vent flow did go up upon fan start and is currently 107500 cfm and lowering. Will continue to monitor building flow and adjust If required to maintain within 50000 to 90000 cfm.
