FUN 2 EO: 1.4-h - Radiation Protection Tech.

FUN 2 EO: 1.4-h

1 / 10

Jet pump assemblies in the reactor vessel are primarily:

Located between the core shroud and the vessel wall

Positioned above the reactor core

Attached to the reactor vessel's top head

Located within the core plate

2 / 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

3 / 10

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

Recirculation pumps

Core spray spargers

Moisture separators

Neutron monitoring instruments

4 / 10

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

Moisture separators remove water from steam

Water is pumped back into the reactor vessel

Coolant travels down through the core releasing heat

Very pure water moves upward through the core absorbing heat

5 / 10

In the event of a recirculation line break:

Reactor water level decreases rapidly, uncovering the core

The reactor vessel internals become dry

Moisture separators prevent core exposure

The reactor automatically shuts down

6 / 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

7 / 10

The reactor vessel support skirt's role is to:

Facilitate refueling operations

House the emergency core cooling systems

Direct coolant up through the fuel assembly

Mount the vessel to the reactor vessel support pedestal

8 / 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

9 / 10

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

A series of external pumps

Movement of bottom entry control rods

Manual adjustment of fuel rods

Variation in the coolant flow

10 / 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
