FUN 2 EO: 1.4-h

1 / 10

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

A series of external pumps

Manual adjustment of fuel rods

Movement of bottom entry control rods

Variation in the coolant flow

2 / 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

3 / 10

The boiling water reactor fuel bundle is unique because it:

Lacks neutron monitoring instruments

Does not utilize control rods

Is not impacted by steam voids

Is enclosed in a fuel channel

4 / 10

The primary purpose of the reactor vessel assembly is to:

House the reactor core

Generate steam for the plant

Store unused fuel rods

Cool the reactor turbine

5 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

Reactor water level decreases rapidly, uncovering the core

The reactor automatically shuts down

The reactor vessel internals become dry

6 / 10

The reactor vessel support skirt's role is to:

Facilitate refueling operations

House the emergency core cooling systems

Mount the vessel to the reactor vessel support pedestal

Direct coolant up through the fuel assembly

7 / 10

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

The use of multiple condensers

The lack of moisture separators

A varied reactor power by adjusting fuel rods

The steam void formation in the core

8 / 10

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

Moisture separators remove water from steam

Coolant travels down through the core releasing heat

Water is pumped back into the reactor vessel

Very pure water moves upward through the core absorbing heat

9 / 10

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

Core spray spargers

Neutron monitoring instruments

Moisture separators

Recirculation pumps

10 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located within the core plate

Positioned above the reactor core

Located between the core shroud and the vessel wall

Attached to the reactor vessel's top head
