• Upper Guide Structure

• Core Support Barrel

In the RVLMS indications, the top of the hot leg is between lights...

• #3 and #4

• #4 and #5

• #5 and #6

• #6 and #7

The plant is at full power

A Loss of Offsite Power occurs

All equipment responds as expected

The Pressurizer level lowers to 34%

Subsequently, the Pressurizer level recovers to 40%. At that point, assuming NO operator action, which banks of Pressurizer heaters are energized?

• Heaters powered from LCC-15 ONLY

• No heaters are energized

• Heaters powered from LCC-15 AND LCC-16

• Heaters powered from LCC-16 ONLY

What is a consequence of energizing C-150A, Aux Hot Shutdown Panel, with SS-TAVE, Ave Temp Display Select, in the "LOOP 1 TAVE" position?

• P-8B, Steam Drive Aux Feed Pump, receives a start signal

• Atmospheric Steam Dump Valves get a quick open signal

• PCS Loop 2B WR Tcold TI-0125C fails low on C-150A

• Atmospheric Steam Dump Valves fail closed

At what temperature is LTOP required to be in service and what is the PORV pressure relief path?

• <= 430°F

  Quench Tank

• <=430°F

  Primary System Drain Tank

• <=460°F

  Primary System Drain Tank

• <=460°F

  Quench Tank

Which set of temperature readings represents a set of conditions where the reactor must be tripped?

• Lower Seal = 170°F with no CCW cooling available

  Two seal stages failed

  P-50B vibrations = 20 mils

• Upper Thrust Bearing = 180°F with no CCW cooling available

  One seal stage failed

  P-50B vibrations = 25 mils

• Upper Guide Bearing = 180°F with no CCW cooling available

  One seal stage failed

  P-50B vibrations = 20 mils

• Lower Guide Bearing = 180°F with no CCW cooling available

  Two seal stage failed

  P-50B vibrations = 25 mils

The plant is at full power

The VCT level is initially 55% and Charging Pump suction is in its normal lineup

During a transient, the VCT level lowers to 5% and then subsequently recovers to 25%

Assuming that all automatic actions occurred as expected, What is the current alignment of following valves that provide suction to the Charging Pumps?

MO-2087, VCT Outlet

MO-2160, SIRW Outlet

• MO-2087 is open

  MO-2160 is open

• MO-2087 is closed

  MO-2160 is open

• MO-2087 is closed

  MO-2160 is closed

• MO-2087 is open

  MO-2160 is closed

The plant trips from full power with two full length control rods not fully inserted.

Bus 1D develops a fault and is deenergized

Emergency Boration is required. Which pump and valve(s) must be used?

• P-56A, Boric Acid Transfer Pump

  MO-2169 & MO-2170, Boric Acid Gravity Feed Isolations

• P-56B, Boric Acid Transfer Pump

  MO-2140, Boric Acid Pump Feed Isolation

• P-56B, Boric Acid Transfer Pump

  MO-2169 & MO-2170, Boric Acid Gravity Feed Isolations

• P-56A, Boric Acid Transfer Pump

  MO-2140, Boric Acid Pump Feed Isolation

The 'B' Channel of Pressurizer Level Control is in service in the CASCADE mode at full power.

A failure on LIC-0101B causes program level to fail low to 0%.

Operator action is taken to swap handswitch 1/LRC-0101, Pressurizer Level Control Channel Selector Switch, to the Channel 'A' position in CASCADE mode. Program Level on the 'A' Channel is 57%

No other operator action is taken.

What is the status of Letdown valves CV-2003 and Pressurizer heaters?

• CV-2003 is open

  all Pressurizer heaters are deenergized

• CV-2003 is closed

  all Pressurizer heaters are energized

• CV-2003 is closed

  all Pressurizer heaters are deenergized

• CV-2003 is closed

  all Backup Pressurizer heaters are deenergized and Proportional heaters are energized

(SRO ONLY)

The plant is at full power.

During a routine surveillance, PCS Loop 1 WR Tcold TI-0112CAA on C-150A is found to be failed low when the panel is energized.

(T.S. 3.3.7 and 3.3.8 may be used as references)

• No Tech Spec actions apply

• Tech Spec 3.3.7 Action A

• Tech Spec 3.3.8 Action A

• Tech Spec 3.3.7 Action A

  and

  Tech Spec 3.3.8 Action A
