2104-5.1 Revision 2 01/19/78 i
2.0 LIMITS AND PRECAUTIONS 2.1 Equipment 2.1.1 Prior to operating the RS Normal Cooling Water Pumps verify the RB Surge Tank is at its normal level.
2.1.2 The RR pump differential pressure (Poutlet-Pinlet) should be maintained above 43 psi to p".ent pump runout.
2.2 Administrative 2.2.1 If possible, the Reactor Building ambient should be maintained below 127 F. Damage may occur with an air temperature greater than 135 F or a concrete temperature of 200 F.
With a loss of cooling, the temper ture will rapidly increase at a rate of approximately 1 F/ min.
2.2.2 Ensure that cooling water is only flowing through the cooling coils for the Units which have a fan in operation.
2.2.3 River water should not be pumped through the fan coil units
( AH-C-13A-E. and AH-C-14A-E) unless absolutely necessary.
Flush the coils and associated piping before returnirg the Reactor Building Normal Cooling Water System to seriice.
2.2.4 Do not reposition dampers throttled for air balancin1 2.2.5 Cooling Coil Outlet Valves (RR-V26A, 268, 79, 26C, 26D and 26E) should not be used to secure cooling water flow to the associated cooling unit when switching operating cooling fans, since these valves do not receive an ES signal to open.
RR-V5A, 5B, SC or 6C, 6D and 6E should be.used for this purpose.
f 2.2.6 Manual control of the Evaporative dampers should be used with extreme care during freezing weather.
Automatic pan heater control and automatic damper control must be used together for 3.0 185 149 x
- s..
2104-5.1 Revision 2 01/19/78 proper freeze protection.
If automatic damper control is unavailable during freezing weather, manually position the inlet and outlet dampers in the most closed position and the bypass damper in the most open position that will maintain U
cooling water outlet from the Evaporator below 85 F (RB-TI-2001/2002).
2.2.7 Ensure RB Normal Heat Tracing Protection is available before cold weather.
RB-Z-1 A and 1B heat tracing is controlled from Panels 1T-P-l'A, 148, 15 and 16.
2.2.8 Per Tech. Spec. 3.6.2.3 (Modes 1, 2 and 3) two RB Fans (AH-E-llA, Bov:) associated cooling coils anc one RR pump must be operable and powered from 480V BUS Z-ilE and two RB Fan; AH-E-llc, D or E) associated cooling coils and one RR pump must be operable and powered from Z-21E.
2.2.9 RR-V26A-E and RR-V79 must be open and their associated 480V breakers locked open, since these valves do not receive an ES signal.
2.2.10 Per Tech Spec 3.6.1.5 the R.B. average air temperature shall U
not exceed 130 F in Modes 1, 2, 3 and 4.
2.2.l' Reactor Building Fans (AH-E-ll A-E) should always be operated in the fast speed except for RB proof pressure test.
2.2.12 If additional RB fans are required af ter a loss of normal power, approximately 2 minutes after the Diesel Generator is online they may be started by placing the associated control I
switch in EM. MAN. ON.
2.2.13 Reactor Building fan AH-E-llc has two sources of power (2-llE and 2-21E).
If the feeder breaker from either source is open, 4-185 150 e
e---
_e_-een O
2104-5.1 Revision 2 01/19/78 the fan cannot be started on the other source.
This is due to the de-energized relay in the circuitry of the open breaker.

1.2 River water ficw from the Nuclear Services River Water header should fill the Emergency Cooling Booster Pump casings and purge the pump casings through the test discharge lines.
Briefly jog RR-P-1A,1B,1C and ID using the local control switches to ensure the pumps are thoroughly purged of air.
1.3 After the pump suction lines, casings and discharge lines up to the test discharge valves have been filled and purged, CLOSE RR-V-3A, 3B, 3C and 3D.
2 Filling and Ven'"g Reactor Building Normal Cooling System.
2.1 OPEN RB-V-53 and ensure RB normal cooling water surge tank (RB-T-1) is filled to normal level (29").
2.2 Place both Evaporative Coolers in operation by positioning the
~
Panel 318 switch for each cooler in START.
Observe that RB-V9A-and B open.
2.3 OPEN Evaporative Cooler Coil outlet vents RB-V39A, 298, 39C, 390, 39E, 39F, 39G, and 39H for RB-Z-1B, and RB-V35A, 358, 35C, 35D, 35E, 35F, 35G, and 35H for RB-Z-1 A.
CLOSE each of these vents when a steady stream of clear water appears.
2.4 OPEN RS Cooling Coil outlet vents RR-V45A through 45E, RR-V46A through 46E, RR-V47A through 47E, RR-V51A through SlE, RR-V52A through 52E, RR-V53A through 53E, RR-V59A, RR-V60, RR-V61, RR-V62 and RR-V63. CLOSE each of these vents when a steady stream of clear water appears.
2.5 START RB-P-1A or 1B by placing the Panel 318 control switch in the START position.

If surge tank level is belcw the visible range, stop the running pump until surge tank level has been restored.
2.6 Continue operation of RB-P-1A or 18 and repeat steps 2.3 and 2.4 above.
_2. 7 When the system has been thoroughly vented, STCP the operating pump by placing its Panel 318 control switch in the PULL-TO-LOCK position.
2.8 START the other RB cooling water pump by placing the Panel 318 control switch in the' START position.
2.9 Operate RC-P-1A or 18 and repeat steps 2.3 and 2.4 above.
2.10 When the system has been thoroughly filled and vented, add chemicals to the system per section 4.6.
2.11 If operation of the RB Normal Cooling System is not required, shut down the Evaporative Coolers and the cooling water pump by placing their Panel 318 control switches in the PULL-TO-LOCK position.
