FUN 2 EO: 1.4-h

1 / 10

The boiling water reactor fuel bundle is unique because it:

Lacks neutron monitoring instruments

Does not utilize control rods

Is enclosed in a fuel channel

Is not impacted by steam voids

2 / 10

The reactor vessel support skirt's role is to:

Direct coolant up through the fuel assembly

House the emergency core cooling systems

Facilitate refueling operations

Mount the vessel to the reactor vessel support pedestal

3 / 10

The Boiling Water Reactor (BWR) produces a steam-water mixture when:

Coolant travels down through the core releasing heat

Moisture separators remove water from steam

Very pure water moves upward through the core absorbing heat

Water is pumped back into the reactor vessel

4 / 10

The steam-water mixture in the BWR after leaving the core:

Is released to the environment

Moves to the emergency core cooling systems

Enters the two stages of moisture separation

Goes directly to the turbine

5 / 10

The primary difference in the operation of a BWR compared to other nuclear systems is:

The steam void formation in the core

The use of multiple condensers

A varied reactor power by adjusting fuel rods

The lack of moisture separators

6 / 10

In the event of a recirculation line break:

Reactor water level decreases rapidly, uncovering the core

Moisture separators prevent core exposure

The reactor vessel internals become dry

The reactor automatically shuts down

7 / 10

Jet pump assemblies in the reactor vessel are primarily:

Attached to the reactor vessel's top head

Located between the core shroud and the vessel wall

Located within the core plate

Positioned above the reactor core

8 / 10

Which component is NOT an internal part of the reactor vessel?

Core spray spargers

Moisture separators

Neutron monitoring instruments

Recirculation pumps

9 / 10

To regulate the power of the core, the BWR uses:

A series of external pumps

Manual adjustment of fuel rods

Variation in the coolant flow

Movement of bottom entry control rods

10 / 10

The primary purpose of the reactor vessel assembly is to:

Store unused fuel rods

House the reactor core

Generate steam for the plant

Cool the reactor turbine
