FUN 2 EO: 1.4-h

1 / 10

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

The lack of moisture separators

The steam void formation in the core

The use of multiple condensers

A varied reactor power by adjusting fuel rods

2 / 10

The primary purpose of the reactor vessel assembly is to:

Generate steam for the plant

House the reactor core

Cool the reactor turbine

Store unused fuel rods

3 / 10

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

Moves to the emergency core cooling systems

Enters the two stages of moisture separation

Is released to the environment

Goes directly to the turbine

4 / 10

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

Water is pumped back into the reactor vessel

Very pure water moves upward through the core absorbing heat

Moisture separators remove water from steam

Coolant travels down through the core releasing heat

5 / 10

The reactor vessel support skirt's role is to:

Facilitate refueling operations

Mount the vessel to the reactor vessel support pedestal

Direct coolant up through the fuel assembly

House the emergency core cooling systems

6 / 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

7 / 10

In the event of a recirculation line break:

Reactor water level decreases rapidly, uncovering the core

The reactor vessel internals become dry

The reactor automatically shuts down

Moisture separators prevent core exposure

8 / 10

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

Movement of bottom entry control rods

Variation in the coolant flow

Manual adjustment of fuel rods

A series of external pumps

9 / 10

Jet pump assemblies in the reactor vessel are primarily:

Attached to the reactor vessel's top head

Positioned above the reactor core

Located within the core plate

Located between the core shroud and the vessel wall

10 / 10

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

Core spray spargers

Neutron monitoring instruments

Moisture separators

Recirculation pumps
