FUN 2 EO: 1.4-h

1 / 10

The primary purpose of the reactor vessel assembly is to:

Generate steam for the plant

Store unused fuel rods

Cool the reactor turbine

House the reactor core

2 / 10

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

Is released to the environment

Enters the two stages of moisture separation

Goes directly to the turbine

Moves to the emergency core cooling systems

3 / 10

In the event of a recirculation line break:

Reactor water level decreases rapidly, uncovering the core

Moisture separators prevent core exposure

The reactor automatically shuts down

The reactor vessel internals become dry

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

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

Coolant travels down through the core releasing heat

Moisture separators remove water from steam

Very pure water moves upward through the core absorbing heat

Water is pumped back into the reactor vessel

6 / 10

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

Moisture separators

Core spray spargers

Neutron monitoring instruments

Recirculation pumps

7 / 10

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

A varied reactor power by adjusting fuel rods

The use of multiple condensers

The steam void formation in the core

The lack of moisture separators

8 / 10

The boiling water reactor fuel bundle is unique because it:

Lacks neutron monitoring instruments

Is enclosed in a fuel channel

Does not utilize control rods

Is not impacted by steam voids

9 / 10

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

A series of external pumps

Movement of bottom entry control rods

Variation in the coolant flow

Manual adjustment of fuel rods

10 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located between the core shroud and the vessel wall

Located within the core plate

Positioned above the reactor core

Attached to the reactor vessel's top head
