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 use of multiple condensers

The steam void formation in the core

A varied reactor power by adjusting fuel rods

2 / 10

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

A series of external pumps

Variation in the coolant flow

Movement of bottom entry control rods

Manual adjustment of fuel rods

3 / 10

The primary purpose of the reactor vessel assembly is to:

Cool the reactor turbine

Store unused fuel rods

House the reactor core

Generate steam for the plant

4 / 10

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

Neutron monitoring instruments

Recirculation pumps

Moisture separators

Core spray spargers

5 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located within the core plate

Positioned above the reactor core

Located between the core shroud and the vessel wall

Attached to the reactor vessel's top head

6 / 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

7 / 10

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

Goes directly to the turbine

Moves to the emergency core cooling systems

Enters the two stages of moisture separation

Is released to the environment

8 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

The reactor automatically shuts down

Reactor water level decreases rapidly, uncovering the core

The reactor vessel internals become dry

9 / 10

The boiling water reactor fuel bundle is unique because it:

Does not utilize control rods

Lacks neutron monitoring instruments

Is not impacted by steam voids

Is enclosed in a fuel channel

10 / 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

Water is pumped back into the reactor vessel

Very pure water moves upward through the core absorbing heat
