FUN 2 EO: 1.4-h

1 / 10

The primary purpose of the reactor vessel assembly is to:

Generate steam for the plant

Cool the reactor turbine

Store unused fuel rods

House the reactor core

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

A varied reactor power by adjusting fuel rods

The steam void formation in the core

3 / 10

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

Is released to the environment

Goes directly to the turbine

Enters the two stages of moisture separation

Moves to the emergency core cooling systems

4 / 10

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

Variation in the coolant flow

A series of external pumps

Movement of bottom entry control rods

Manual adjustment of fuel rods

5 / 10

The reactor vessel support skirt's role is to:

Mount the vessel to the reactor vessel support pedestal

Facilitate refueling operations

House the emergency core cooling systems

Direct coolant up through the fuel assembly

6 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located between the core shroud and the vessel wall

Attached to the reactor vessel's top head

Located within the core plate

Positioned above the reactor core

7 / 10

The boiling water reactor fuel bundle is unique because it:

Is not impacted by steam voids

Does not utilize control rods

Lacks neutron monitoring instruments

Is enclosed in a fuel channel

8 / 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

9 / 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

Very pure water moves upward through the core absorbing heat

Water is pumped back into the reactor vessel

10 / 10

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

Neutron monitoring instruments

Recirculation pumps

Moisture separators

Core spray spargers
