Question 2

AO actions for Energizing PNA-D25

Answer 2

• breaker position inventory
• place all breakers to “off”
• If D25 to be energized by inverter, align inverter to bus
• If D25 to be energized by voltage regulator, align volt. reg.
• reset alarms
• Inform CR and close all previously closed breakers

Question 3

AO actions for Energizing PKA-M41 from A Battery Charger

Answer 3

• If using ‘A’ Charger, Align charger
• If using ‘AC’ Charger, align charger
• Inform CR

Question 4

AO actions for Aligning SBOG to PBA-S03 (BO)

Answer 4

-Disable S03 breakers
-If DC power not available, open all PBA-S03 supply breakers
-Close NAN-S03AB
-close applicable unit supply breaker
-If no DC power, manually close PBA-S03L
+ then able to close PKAM41
+ then energize PNAD25
-realign battery chargers
-Monitor SBOG loading for closing coping load breakers
-close CHNV836, seal injection HX outlet valve
-assist w/ swapping CHE-P01 power supply

Question 5

AO actions for Minimizing Release to the environment

Answer 5

-Isolate Condenser draw-off, CDNV062/862
-Isolate condensate cross-tie, CDNV250/252
-Isolate CST to Condensate cross-tie, ASNV164
-Open V088, Cond. Receiver Tank to condenser and close V024, Cond. Receiver tank to cross-tie
-Isolate ASNV015 and V014, AS cross-tie
-Inform CR
-Close CDNV099, Cond. Serv. Header PCV outlet
potentially perform APP: 20, AS alignment

Question 6

AO actions for putting LTOP in service

Answer 6

• close appropriate train battery breaker

- unlock and close applicable disconnect

Question 7

AO actions for Excessive RCS leakage

Answer 7

-walk down charging/letdown
-monitor NC surge tank level and pressure
-isolate NC to LDHX
+ if not available, isolate back pressure control valve inlets
-align turbine building sumps to LRS
-isolate condensate X-tie
-isolate CDNV099, condensate service header PCV outlet valve
-isolate applicable charging pump normal discharge
-unlock and open charging pump discharge to HPSI
-close RCP HPSC isolation valve breakers

Question 8

AO actions for loss of charging or letdown

Answer 8

• operate M7208, VCT outlet valve–blending room
• operate CHN-V117, VCT to drain to EDT–blending room
• align letdown and backpressure control valves as necessary and check valves for leakage–100’/110’ Aux
• operate charging pump normal and alternate discharge valves–charging pump ante rooms
• manipulate SIE-V508–100’ Aux CHP valve gallery
• vent CHP’s– 1 AO at vent receiver tank in 88’ pipe chase and another at drain pot in RW

Question 9

Actions to manually trip an 86 relay

Answer 9

• open RRA breaker
• remove cover off lockout relay
• press armature plate down
• close RRA

Question 10

Ao actions for NKN-M46 load reduction and main generator venting

Answer 10

-open NKN-M4608/09 FWPT A/B emergency oil pumps
-open NKN-M4606 main turbine EBOP
-if SBOG is not supplying SWYD loads AND/OR NKN-M45 is not powering U45/U46,
+ensure backup source transfer switches for U45/U46 breakers are closed and CB1/CB2 are in applicable positions
-isolate generator hydrogen supply line and PCV-10 regulator
-put PI, PCV10 bypass and hydrogen supply header vent valves in service
-open vent isolation valve to reduce pressure
-put SO float trap bypass valves and level sight glass in service
-if hydrogen pressure is greater than 8 PSIG, then modulate bypass valves to keep level in sight glass
-if h2 pressure is less than or equal to 8 PSIG, fully open bypass valves
-when CO2 vaporizer has power from NHN-M27, purge generator with CO2

Question 11
