▶ Show Critical Steps & Key Actions
Step Critical Element Standard
CUE Fire alarm actuates: OHA A-7 FIRE PROT TRBL, A-8 FIRE PROT CO2/HALON DISCH, coded fire alarm #91 on 2RP5 Audible coded fire alarm heard in control room (stops after ~30 seconds). Operator responds to 2RP5 coded alarm to identify fire location.
3.1 * Scan 2RP5 to determine Fire Zone, Area, and Elevation Identifies fire alarm on 2RP5 is for Relay Room, 100 ft. elevation (code 91 — Aux. Bldg., Relay & Battery Rooms).
3.3 Notify Emergency Services, dispatch Fire Brigade Liaison, notify RP and SM All notifications made. Fire Brigade Liaison dispatched to scene.
3.4 If alarm is valid, go to S2.OP-AB.FIRE-0001 Goes to S2.OP-AB.FIRE-0001. Records fire information: Unit 2, Auxiliary Bldg., 100 ft. elevation, Relay Room, Zone 91, Fire Suppression activated: YES.
AB 3.3 * Make station page announcement for fire location Completes page announcement: "Attention all personnel — a fire is reported in Unit 2 Relay Room 100 ft. elevation. All personnel please evacuate the area."
AB 3.8 Is the fire in an area serviced by CAACS or Chiller Room YES — the Relay Room is in the area serviced by CAACS.
AB 3.9 * At 2RP2, select FIRE INSIDE CONTROL AREA At 2RP2 panel, depresses the pushbutton for FIRE INSIDE CONTROL AREA.
AB 3.10 * Direct Unit 1 NCO to select FIRE INSIDE CONTROL AREA Directs Unit 1 NCO to select FIRE INSIDE CONTROL AREA.
AB 3.19.A * Select MANUAL and CLOSE on PORVs 2PR1 and 2PR2 Depresses MANUAL pushbutton for 2PR1 and 2PR2 on 2CC2 console. (Note: 2PR1 and 2PR2 are normally closed during power operation.)
AB 3.19.B * CLOSE PORV Block Valves 2PR6 and 2PR7 Depresses CLOSE pushbutton for 2PR6 and 2PR7 (STOP VALVES) on 2CC2 console.
AB 3.20 * Dispatch operator to align PORV block valve circuits to EMERG CLOSE per Attachment 15 Dispatches operator to perform step 3.20.
Key Decision Point:
Step 3.1 (from the ARP) is the discriminating step. The applicant must correctly identify the fire location from the 2RP5 coded fire alarm (code 91 = Aux. Bldg., Relay & Battery Rooms, 100 ft. elevation). This identification drives the entire procedure path — because the fire is in the Relay Room (an area serviced by CAACS), the operator must place ventilation in FIRE INSIDE mode and isolate the PORVs (since the Relay Room contains PORV control circuitry). If the fire location is incorrectly identified, the wrong fire response actions will be performed.
