FUN 2 EO: 1.4-h

1 / 10

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

Moisture separators remove water from steam

Very pure water moves upward through the core absorbing heat

Coolant travels down through the core releasing heat

Water is pumped back into the reactor vessel

2 / 10

The boiling water reactor fuel bundle is unique because it:

Is not impacted by steam voids

Does not utilize control rods

Is enclosed in a fuel channel

Lacks neutron monitoring instruments

3 / 10

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

Moisture separators

Neutron monitoring instruments

Recirculation pumps

Core spray spargers

4 / 10

The reactor vessel support skirt's role is to:

Direct coolant up through the fuel assembly

Mount the vessel to the reactor vessel support pedestal

Facilitate refueling operations

House the emergency core cooling systems

5 / 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

6 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

The reactor automatically shuts down

The reactor vessel internals become dry

Reactor water level decreases rapidly, uncovering the core

7 / 10

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

Manual adjustment of fuel rods

Variation in the coolant flow

Movement of bottom entry control rods

A series of external pumps

8 / 10

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

The lack of moisture separators

The steam void formation in the core

A varied reactor power by adjusting fuel rods

The use of multiple condensers

9 / 10

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

Enters the two stages of moisture separation

Moves to the emergency core cooling systems

Is released to the environment

Goes directly to the turbine

10 / 10

The primary purpose of the reactor vessel assembly is to:

Cool the reactor turbine

House the reactor core

Store unused fuel rods

Generate steam for the plant
