FUN 2 EO: 1.4-h

1 / 10

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

Manual adjustment of fuel rods

Movement of bottom entry control rods

A series of external pumps

Variation in the coolant flow

2 / 10

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

Goes directly to the turbine

Is released to the environment

Enters the two stages of moisture separation

Moves to the emergency core cooling systems

3 / 10

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

The steam void formation in the core

The use of multiple condensers

A varied reactor power by adjusting fuel rods

The lack of moisture separators

4 / 10

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

Recirculation pumps

Moisture separators

Neutron monitoring instruments

Core spray spargers

5 / 10

The reactor vessel support skirt's role is to:

Facilitate refueling operations

House the emergency core cooling systems

Mount the vessel to the reactor vessel support pedestal

Direct coolant up through the fuel assembly

6 / 10

The boiling water reactor fuel bundle is unique because it:

Is enclosed in a fuel channel

Lacks neutron monitoring instruments

Is not impacted by steam voids

Does not utilize control rods

7 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

The reactor vessel internals become dry

Reactor water level decreases rapidly, uncovering the core

The reactor automatically shuts down

8 / 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

9 / 10

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

Coolant travels down through the core releasing heat

Water is pumped back into the reactor vessel

Very pure water moves upward through the core absorbing heat

Moisture separators remove water from steam

10 / 10

The primary purpose of the reactor vessel assembly is to:

Cool the reactor turbine

Store unused fuel rods

Generate steam for the plant

House the reactor core
