FUN 2 EO: 1.4-h

1 / 10

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

Moisture separators

Core spray spargers

Recirculation pumps

Neutron monitoring instruments

2 / 10

The boiling water reactor fuel bundle is unique because it:

Lacks neutron monitoring instruments

Is enclosed in a fuel channel

Is not impacted by steam voids

Does not utilize control rods

3 / 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 lack of moisture separators

The use of multiple condensers

The steam void formation in the core

4 / 10

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

Movement of bottom entry control rods

Manual adjustment of fuel rods

Variation in the coolant flow

A series of external pumps

5 / 10

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

Very pure water moves upward through the core absorbing heat

Moisture separators remove water from steam

Water is pumped back into the reactor vessel

Coolant travels down through the core releasing heat

6 / 10

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

Moves to the emergency core cooling systems

Is released to the environment

Goes directly to the turbine

Enters the two stages of moisture separation

7 / 10

In the event of a recirculation line break:

The reactor vessel internals become dry

Reactor water level decreases rapidly, uncovering the core

The reactor automatically shuts down

Moisture separators prevent core exposure

8 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located within the core plate

Positioned above the reactor core

Attached to the reactor vessel's top head

Located between the core shroud and the vessel wall

9 / 10

The primary purpose of the reactor vessel assembly is to:

House the reactor core

Store unused fuel rods

Generate steam for the plant

Cool the reactor turbine

10 / 10

The reactor vessel support skirt's role is to:

Direct coolant up through the fuel assembly

Facilitate refueling operations

House the emergency core cooling systems

Mount the vessel to the reactor vessel support pedestal
