FUN 2 EO: 1.4-h

1 / 10

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

Water is pumped back into the reactor vessel

Very pure water moves upward through the core absorbing heat

Coolant travels down through the core releasing heat

Moisture separators remove water from steam

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

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

4 / 10

The reactor vessel support skirt's role is to:

House the emergency core cooling systems

Facilitate refueling operations

Mount the vessel to the reactor vessel support pedestal

Direct coolant up through the fuel assembly

5 / 10

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

Recirculation pumps

Moisture separators

Neutron monitoring instruments

Core spray spargers

6 / 10

The primary purpose of the reactor vessel assembly is to:

Cool the reactor turbine

Generate steam for the plant

Store unused fuel rods

House the reactor core

7 / 10

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

Is released to the environment

Enters the two stages of moisture separation

Moves to the emergency core cooling systems

Goes directly to the turbine

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

In the event of a recirculation line break:

The reactor vessel internals become dry

The reactor automatically shuts down

Reactor water level decreases rapidly, uncovering the core

Moisture separators prevent core exposure

10 / 10

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

Variation in the coolant flow

Manual adjustment of fuel rods

A series of external pumps

Movement of bottom entry control rods
