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:

Attached to the reactor vessel's top head

Located within the core plate

Located between the core shroud and the vessel wall

Positioned above the reactor core

2 / 10

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

The use of multiple condensers

The lack of moisture separators

A varied reactor power by adjusting fuel rods

The steam void formation in the core

3 / 10

The reactor vessel support skirt's role is to:

Direct coolant up through the fuel assembly

House the emergency core cooling systems

Facilitate refueling operations

Mount the vessel to the reactor vessel support pedestal

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

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

Core spray spargers

Neutron monitoring instruments

Moisture separators

Recirculation pumps

6 / 10

The boiling water reactor fuel bundle is unique because it:

Lacks neutron monitoring instruments

Is enclosed in a fuel channel

Does not utilize control rods

Is not impacted by steam voids

7 / 10

In the event of a recirculation line break:

Reactor water level decreases rapidly, uncovering the core

The reactor automatically shuts down

The reactor vessel internals become dry

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

The primary purpose of the reactor vessel assembly is to:

Cool the reactor turbine

House the reactor core

Generate steam for the plant

Store unused fuel rods

10 / 10

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

Goes directly to the turbine

Is released to the environment

Moves to the emergency core cooling systems

Enters the two stages of moisture separation
