If temperatures approach a predetermined limit, then actions will be taken to reduce RB temperatures to acceptable values.

Limits And Precautions Large break LOCAs and larger small break LOCAs will result in RB Pressures that actuate building spray automatically. Actions to manually start building spray to reduce RB temperatures will not be required in these situations.
Prior to starting any ES powered component, adequate load margin must be available if the ES 4160 volt busses are energized from the emergency diesel generators.
EM-225C Rev. 3 Page 3 of 7
3.3.3 Prior to starting a building spray pump, building spray flow control valves must be set for 1200 gpm if ECCS suction has been transferred to the RB Sump.
3.3.4 If a SGTR is in progress then ensure adequate RB sump level is available prior to transferring or starting a BS pump from the RB Sump. With a SGTR, sufficient RB sump level might not be available due to loss from the SGTR. Reference calculation M-90-0021 for BSP NPSH requirements.
4.0 INSTRUCTIONS 4.1 IF at least one building spray pump is running, THEN exit this procedure. No further action is required.
4.2 IF an RCS leak is occurring in the reactor building, THEN begin plotting average RB temperature on Enclosure 1 for at least 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> intervals in the beginning of the event. The plotting interval can be changed based on plant conditions.
4.3 RB Temperature is the average of the following four temperature elements:
TEMPERATURE CONTROL RECALL COMPUTER RB ELEV.
ELEMENT ROOM POINT POINT RECORDER AH-536-TE AH-536-TIR RECL-77 S358 102 AH-537-TE RECL-78 S359 125 AH-538-TE RECL-80 S382 180 AH-539-TE RECL-81 S383 235 AVERAGE S837 4.4 IF average RB Temperature is in the Acceptable' Region of Enclosure 1 and decreasing, THEN exit this procedure.
4.5 IF at any time average RB temperature reaches "Action Required boundary region of Enclosure 1, THEN obtain Emergency Coordinator concurrence to start at least one building spray pump.
4.6 IF a building spray pump is required and EC concurrence has been obtained, THEN perform the following:
4.6.1 Ensure load is available on the emergency diesel generators per EOP-13, Rule 5.
4.6.2 Ensure Building Spray flow controls are set at 1500 GPM and "Remote" if pumps are aligned to BWST, or 1200 GPM and "LOCAL" if aligned to the RB Sump.
4.6.3 Notify the control room to start one building spray pump.
4.7 Continue to monitor RB Temperature.
EM-225C Rev. 3 Page 4 of 7
4.8 IF RB Temperature does not lower to the acceptable region of Enclosure 1, THEN notify control room to start a second building spray pump if available.
NOTE If building spray pumps are running, Emergency Operating Procedures provide guidance to secure them. If building spray pumps are secured, begin additional monitoring of RB Temperatures until a continuing decreasing trend is achieved.
4.9 5.0 WHEN building spray pumps are running, THEN exit this procedure.
