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

FUN 2 EO: 1.4-h

1 / 10

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

Variation in the coolant flow

Movement of bottom entry control rods

A series of external pumps

Manual adjustment of fuel rods

2 / 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

3 / 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

4 / 10

In the event of a recirculation line break:

The reactor vessel internals become dry

Moisture separators prevent core exposure

Reactor water level decreases rapidly, uncovering the core

The reactor automatically shuts down

5 / 10

The reactor vessel support skirt's role is to:

Direct coolant up through the fuel assembly

Mount the vessel to the reactor vessel support pedestal

Facilitate refueling operations

House the emergency core cooling systems

6 / 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

Positioned above the reactor core

Located within the core plate

7 / 10

The primary purpose of the reactor vessel assembly is to:

Generate steam for the plant

Store unused fuel rods

Cool the reactor turbine

House the reactor core

8 / 10

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

Moves to the emergency core cooling systems

Goes directly to the turbine

Enters the two stages of moisture separation

Is released to the environment

9 / 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

10 / 10

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

Recirculation pumps

Moisture separators

Neutron monitoring instruments

Core spray spargers
