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

FUN 2 EO: 1.4-h

1 / 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

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

The steam void formation in the core

A varied reactor power by adjusting fuel rods

3 / 10

In the event of a recirculation line break:

Moisture separators prevent core exposure

Reactor water level decreases rapidly, uncovering the core

The reactor vessel internals become dry

The reactor automatically shuts down

4 / 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

5 / 10

The boiling water reactor fuel bundle is unique because it:

Does not utilize control rods

Lacks neutron monitoring instruments

Is enclosed in a fuel channel

Is not impacted by steam voids

6 / 10

Jet pump assemblies in the reactor vessel are primarily:

Positioned above the reactor core

Located between the core shroud and the vessel wall

Located within the core plate

Attached to the reactor vessel's top head

7 / 10

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

Neutron monitoring instruments

Moisture separators

Recirculation pumps

Core spray spargers

8 / 10

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

Variation in the coolant flow

Manual adjustment of fuel rods

A series of external pumps

Movement of bottom entry control rods

9 / 10

The primary purpose of the reactor vessel assembly is to:

Store unused fuel rods

House the reactor core

Cool the reactor turbine

Generate steam for the plant

10 / 10

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

Coolant travels down through the core releasing heat

Very pure water moves upward through the core absorbing heat

Water is pumped back into the reactor vessel

Moisture separators remove water from steam
