Select which valves are Interlocked to be closed with the Mode switch in Run?

AO-2378, AO-2381 (18" Torus and DW Purge lines)

AO-2377 (18" Common Purge Line)

AO-2383 and AO-2386 (Torus and DW 18" Vent lines)

AO-2379/AO-2380 (Rx Building to Torus Vacuum Breakers)

Choose all SBGT initiation signals

one downscale in RB Refuel floor

A Reactor startup is in progress with containment inerting occurring IAW Procedure 2138 (INERTING THE PRIMARY CONTAINMENT DURING REACTOR STARTUP). While transferring nitrogen flow from the Drywell to the Suppression Chamber the following indications are noted: What is the concern?

A suppression pool bypass path exists which makes the suppression pool inoperable.

High N2 flow to the drywell may cause chugging at the downcomers.

High N2 flow to the torus may cause excessive cycling of the torus to drywell vacuum breakers.

If a SBGT fan trip occurred, drywell pressure would exceed 1.84 psig prior to being able to secure N2 flow.

The plant is operating at rated conditions when a large steam leak occurs in the Steam Jet Air Ejector room. If the SBGT system automatically initiates, what will happen to radiation levels in the RB Exhaust Plenum Room, and why? Radiation levels will…

rise because SJAE room exhaust will be redirected to the RB Exhaust Plenum room

lower because the Turbine Building supply fans will trip

rise because the Plenum room exhaust fans take suction from the SJAE room

lower because the SBGT system will be processing the steam leak from the SJAE room

Which of the following IS allowed in the Spent fuel pool

An unlabeled laynard with someone continuously present

The unloading of a core cell of all fuel was required to support an inspection during a refueling outage. Which of the following describes the correct sequence of events to be performed for this refueling process?

Unload two diagonal fuel assemblies, insert a blade guide, remove the remaining fuel assemblies, withdraw the control rod, install jumper on Probe Buffer Card to allow bridge movement over the core

Install the blade guide, install jumper on Probe Buffer Card to allow bridge movement over the core, remove all fuel assemblies, withdraw the control rod

Remove all fuel assemblies, install the blade guide, withdraw the control rod, install jumper on Probe Buffer Card to allow bridge movement over the core

Unload two diagonal fuel assemblies, insert a blade guide, withdraw the control rod, remove the remaining fuel assemblies, install jumper on Probe Buffer Card to allow bridge movement over the core

Fuel Bundles are being shuffled inside the Spent Fuel Pool. It has been reported to the control room that a fuel bundle has come in contact with the side of the pool. The following conditions now exist: • Annunciator 4-A-1 (REFUELING FL AREA HI RADIATION) is in alarm • RM-17-453A, Fuel Pool Monitor Channel A, indicates 30 mr/hr and rising • RM-17-453B, Fuel Pool Monitor Channel B, indicates 25 mr/hr and rising Which one of the following is the correct response to these conditions?

Evacuate the Reactor Building AND the Refuel Floor to reduce personnel exposure

Verify SBGT automatically initiated to minimize the potential release outside the Reactor Building

Evacuate the Refuel Floor ONLY to reduce personnel exposure.

Monitor local ARM readings and evacuate the refuel floor if indications approach 50 mr/hr

Refueling activities are in progress with the fuel pool gates open and there is notification of lowering fuel pool level.

Place bundle in nearest available location in spent fuel pool

The plant is operating at 100% power. Drywell pressure is 1.1 psig. The ‘B’ train of SBGT is in service in accordance with B.04.01-05.G.4, “Venting Primary Containment Through Standby Gas Treatment System” to reduce drywell pressure. The following alarms are received. 5-B-28, “DRYWELL HI PRESSURE SCRAM TRIP” 8-B-18, “NO. 15 4160V BUS LOCKOUT” The status of SBGT system is .

‘A’ train is not running and ‘B’ train is running in manual

‘A’ train is running after automatic initiation and ‘B’ train has tripped

‘A’ train is not running and ‘B’ train has tripped and restarted on system low flow

'A’ train is running after automatic initiation and ‘B’ train is running in manual

What effect will the failure of the ‘B’ RPS MG have on the SBGT system with the reactor at rated conditions?

SBGT train ‘A’ should start

SBGT train ‘B’ should start

Neither SBGT trains should start

Correct response to a refueling Error with the grapple still latched to the grapple

Return component to location Halt refueling activities Inform nuclear engineer

Halt all refueling activities Inform Nuclear engineer Return Component to correct location

Evacuate refuel floor Inform nuclear engineer

Lower into nearest available location Inform nuclear engineer

Purpose of Rx Building to Torus Vacuum Breakers

PCIV Torus to RB and prevent exceeding 2 PSIG Torus external pressure

Prevent Exceeding Internal Torus Pressure of 2 PSIG by opening at .5 PSID

Open at .5 PSID to Prevent drawing a vacuum in the DW

Prevent exceeding .5 PSIG in the torus

The plant is at 100% power. The Reactor Building Operator reports that he has observed a severe steam leak from the area of MO-2398, RWCU INLET OUTBOARD ISOL, via the surveillance camera video monitor. Actions taken to isolate the leak have been partially successful. The Control Room Operator reports that area radiation monitor A-8, “962’ Outside RWCU,” and the Vent WRGM are approaching their alarm set points. Based on the above information, what action should be taken AND what will be the result?

Push both TEST push buttons on Panels C-24A and C-24B to isolate secondary containment with SBGT train A running.

Push both TEST push buttons on Panels C-24A and C-24B to isolate secondary containment while maintaining normal Turbine Building ventilation.

Place hand switches HS-4887 on Panel C-24A and HS-4888 on Panel C-24B to BYPASS and Push both TEST push buttons on Panels C-24A and C-24B to isolate secondary containment with SBGT train A running.

Place hand switches HS-4887 on Panel C-24A and HS-4888 on Panel C-24B to BYPASS and Push both TEST push buttons on Panels C-24A and C-24B to isolate secondary containment while maintaining normal Turbine Building ventilation.
