▶ Show Critical Steps & Key Actions
| Step | Critical Element | Standard |
|---|---|---|
| 1.0 | OBTAIN: copy of procedure, radio (Appendix R Cabinet), key ring set and tools (JA Master, Breaker Keyswitch, screwdriver, adjustable wrench), Security Master Key from Unit 1 CRS | Operator reviews S1.OP-AB.CR-0001 Att. 5 and proceeds to El. 84 switchgear room. |
| 2.0 * | PROCEED to Rod Drive MG Set Control Panel (460V Vital Bus Room - El 84 ft.) AND OPEN the following breakers: 2.1 Reactor Trip Breaker A 2.2 Reactor Trip Breaker B 2.3 Reactor Trip Bypass Breaker A 2.4 Reactor Trip Bypass Breaker B |
Operator simulates opening breakers by simulating removing cover and depressing the trip (open) pushbuttons for all four breakers. |
| 3.0 | CONFIRM with the Hot Shutdown Panel Operator (PO) that 11 or 12 Charging Pump is operating | Confirms 11 Charging Pump is operating. |
| 4.0 * | PROCEED to 1AX1AX7X, #13 Charging Pump breaker AND OPEN the breaker | Locates 1AX1AX7X, #13 Charging Pump breaker AND simulates depressing the trip PB to open the breaker. |
| 5.0 * | PROCEED to 1C West Valve & Misc 230V Control Center - El 84 ft. AND OPEN Breaker 1CY2AX4I, 1CV175 - Rapid Borate Stop Valve | Locates 1C West Valve & Misc 230V Control Center - El 84 ft. and simulates opening Breaker 1CY2AX4I, 1CV175 - Rapid Borate Stop Valve. |
| 6.0 | NOTIFY the CRS of the following: 6.1 The Reactor Trip and Bypass breakers are OPEN 6.2 #13 Charging Pump Breaker is OPEN |
Contacts CRS and reports the Reactor Trip and Bypass breakers are open and #13 Charging Pump Breaker is open. |
Key Decision Point:
Step 2.0 is the primary discriminating step — the applicant must locate the Rod Drive MG Set Control Panel in the 460V Vital Bus Room at El 84 ft. and open ALL FOUR breakers (Trip A, Trip B, Bypass A, Bypass B). Opening only the trip breakers without the bypass breakers would be unsatisfactory. Steps 4.0 and 5.0 test the applicant's knowledge that during a control room evacuation without a prior reactor trip, the 13 Charging Pump must be tripped (to stop uncontrolled charging) and the 1CV175 Rapid Borate Stop Valve breaker must be opened (to de-energize the valve and stop potential uncontrolled boration).
