1.0 INTRODUCTION
The intent of this lesson is to introduce / review the Serious Control Room Fire Abnormal Procedure. The material (s) that you are responsible for is/are stated in the objective for this lesson.
2.0 PRESENTATION A. Symptom (s) that indicate entrance into this abnormal procedure:
- 1. Extremely serious fire in the Control Room or Obi #1 Cable Spread Room requiring a prolonged evacuation of the Control Room.
NOTE: The fire is assumed to be intelligent and may have the capacity to place control circuits is the least desirable position.
B. Operator Actions The instructor has the option of go-NOTE: Operator actions are performed simul- ing to 2.C.4 and.
taneously. This lesson will cover each reviewing final individuals actions. plant conditions prior to covering individual action.
CAUTION: The required operator actions to mitigate Obj #5 this event involve disabling many plant safety systems to prevent inadvertent operation caused by the fire. The procedure assumes the opera-tor actions will place the plant in the safest possible condition and then isolate the compo-nent in that position by removing its power or failing its operating device. The operator actions in some cases are in violation of various technical specifications, however, these actions are necessary to mitigate the event to stabilize the plant in Hot Standby.
- 1. Reactor Operators Obi #3 and #7
- a. Trip the reactor and turbine.
- b. Isolate letdown shut MU2B.

- b. Service Water (1) The Service Water System has been TP-4 aligned to supply the essential CCW, CTMT air coolers, and ECCS room coolers. The return line has been lined up to the
- forebay. Service water has been isolated to AFP suctions, H2 dilution blowers, and TPCW heat exchangers. Power has been <,
removed from all necessary motor operated valves to prevent inadvertent operation.
- c. Component Cooling Water f (1) The CCW System, is aligned with both TP-5 essential headers in service and side I also' supplying the non-essential lines.
The CCW to makeup pump is handjacked open.
The CTMT isolations have been de-energized open to provide RCP thermal barrier ani letdown coolers cooling, ,CCW to the DHR coolers is ensured by failing open CC-1407 and CC-1469 open. Power has been removed from all necessary motor operated valves to prevent inadvertent operation.
d.
?
(1) The AFW System is in a normal SFRCS trip TP-6 lineup with each pump taking suction from the CST and feeding its own OTSG. Power has been removed from the isolation valves to prevent inadvertent operation. The pump speed is being controlled in manual from the Auxiliary Shutdown Panel. Care must be taken to transfer suction to service water when the CST is emptied.
- e. Main Steam (1) The MSIV's have been closed by the SFRCS trip and are maintained closed by isolat-ing instrument air and nitrogen. The atmospheric vents will be used to control' OTSG pressure in manual control from their' handwheel.

-f. Makeup / Letdown /RCS (1) The makeup pumps are aligned to take TP-7, TP-8, TP-9 suction from the BWST and discharge via the bypass to MU 32 into the RCS. The mini-recirc is realigned to the BWST to prevent filling the makeup tank. Seal injection has been isolated along with seal return. All demineralized water sources to the makeup system are isolated.
Power leads from the control room switches to the oil pumps have been cut to prevent loss of the oil pumps. RCS precsure is being monitored by a gage on the sample line from the pressurized. Letdown is isolated at MU 2B and MU 2A. The PORV has been isolated by closing the block valve.
Power has been removed from all necessary motor operated valves to prevent inadver-tent operation. These lineups will maintain the plant in a stable Hot Standby post trip condition until directed to cooldown when offsite support personnel arrive. The lineups assume no active failure of a component occurred prior to a preventive action being taken by the operator. If a failure has occurred, the operator must take appropriate corrective actions to restore the required lineup.
If the fire adversely affects the Makeup Pumps, such that RCS makeup via the Makeup System is not available. The LPI and HPI pumps may be "Piggvbacked" as outlined in Attachment 52 of AB 1203.02, " Serious Station Fire." Prior to starting the LPI pumps mini-recire, flow must be ensured by verifying CCW is available to the decay heat coolers.
