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

The use of multiple condensers

The lack of moisture separators

The steam void formation in the core

A varied reactor power by adjusting fuel rods

3 / 10

Jet pump assemblies in the reactor vessel are primarily:

Positioned above the reactor core

Attached to the reactor vessel's top head

Located between the core shroud and the vessel wall

Located within the core plate

4 / 10

The reactor vessel support skirt's role is to:

Mount the vessel to the reactor vessel support pedestal

Facilitate refueling operations

Direct coolant up through the fuel assembly

House the emergency core cooling systems

5 / 10

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

Recirculation pumps

Core spray spargers

Neutron monitoring instruments

Moisture separators

6 / 10

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

Goes directly to the turbine

Enters the two stages of moisture separation

Is released to the environment

Moves to the emergency core cooling systems

7 / 10

The primary purpose of the reactor vessel assembly is to:

Generate steam for the plant

House the reactor core

Store unused fuel rods

Cool the reactor turbine

8 / 10

The boiling water reactor fuel bundle is unique because it:

Is enclosed in a fuel channel

Is not impacted by steam voids

Does not utilize control rods

Lacks neutron monitoring instruments

9 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

Reactor water level decreases rapidly, uncovering the core

The reactor vessel internals become dry

The reactor automatically shuts down

10 / 10

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

Very pure water moves upward through the core absorbing heat

Water is pumped back into the reactor vessel

Coolant travels down through the core releasing heat

Moisture separators remove water from steam
