Y10 DCSG Nuclear Reactor Quiz

Contain the uranium needed for the reactor

• Fuel Rods

• Moderator

• Daughter Nuclei

• Reactor Core

Smaller nuclei produced in a nuclear reactor

• Daughter Nuclei

• Fission

• Fuel Rods

• Enriched Uranium

Turned by steam from reactor to generate electricity

• Turbine

• Chain reaction

• Enriched Uranium

• Control rods

Used to absorb excess neutrons and prevent a runaway or uncontrolled chain reaction

• Control rods

• Daughter Nuclei

• Chain reaction

• Moderator

Where a large nucleus is split into two smaller nuclei, releasing lots of energy

• Fission

• Turbine

• Fission/ Thermal Neutrons

• Fusion

Substance (usually water or CO2) used to absorb energy from the nuclear reactor to generate electricity.

• Coolant

• Moderator

• Reactor Core

• Control rods

Slow moving neutrons which combine with Uranium-235 nuclei, causing them to become unstable and split into two smaller nuclei

• Fission/ Thermal Neutrons

• Daughter Nuclei

• Coolant

• Reactor Core

A strong, thick walled steel vessel containing the fuel rods, control rods and coolant and moderator.

• Reactor Core

• Control rods

• Moderator

• Fuel Rods

Where one fission causes several more fission events which themselves cause many more.

• Chain reaction

• Reactor Core

• Control rods

• Coolant

Uranium containing 2-3% Uranium-235 (the isotope which undergoes fission)

• Uranium-238

• Enriched Uranium

• Infused Uranium

• Charged Uranium
