What two actions could be taken to reduce the temperature inside a nuclear reactor?

• Raise the control rods

• Lower the control rods

• Increase coolant flow

• Decrease coolant flow

What would happen if a nuclear reactor was not pressurized?

• The energy in the nuclear reaction would not be used efficiently.

• The energy in the nuclear reaction would be used efficiently.

• The reactor would become contaminated.

Which of the following did not contribute to the nuclear meltdown at Fukushima?

• routine maintenance procedure gone wrong

• water-damaged controls

• faulty power plant design

• a tsunami

Which of the following had the greatest effect on the health of citizens following the Chernobyl meltdown?

• the enormous amount of time it took to physically clean up the city

• the spread of radioactive contamination across Ukraine and neighboring parts of Europe

• the lack of access to medical care

• the hundreds of people left jobless after the meltdown

True or False: The "exclusion zone" around Chernobyl is to keep civilians from accessing a government research facility.

• True

• False

How are nuclear power plants, coal power plants, solar thermal power plants, and natural gas power plants similar?

• They each use fuel sources that are considered clean, and do not emit greenhouse gases like carbon dioxide.

• They each use a fuel source to heat water, create steam, and turn a turbine to generate electricity through electromagnetic induction.

• They each require a large amount of water to operate.

• They each require the use of radioactive materials like uranium-235.

One benefit of nuclear fission reactions is

• nuclear reactor meltdowns

• storage of waste materials

• biological exposure

• production of energy
