Thorium Molten Salt Reactors Quiz

What is the main reason for the renewed interest in thorium-powered molten salt reactors?

• They are cheaper to build than traditional reactors.

• They offer a promising solution to the climate crisis.

• They are easier to maintain than other reactors.

• They have been proven to be more efficient than other reactors.

How does thorium-232 become a viable fuel for nuclear power generation?

• It is mixed with uranium-235 to sustain fission.

• It captures a neutron and eventually decays into uranium-233.

• It directly undergoes fission when exposed to neutrons.

• It is heated to high temperatures to initiate fission.

What is a key advantage of using molten salt as a coolant in reactors?

• It is cheaper than water as a coolant.

• It can passively cool itself without pressurization.

• It is more abundant than water.

• It requires high pressure to remain liquid.

Why is thorium considered more favorable than uranium for long-term nuclear waste management?

• Thorium produces less long-lived radioactive waste.

• Thorium produces no radioactive waste.

• Thorium waste is non-toxic.

• Thorium waste is easier to recycle.

Which countries, besides China, are working on developing thorium reactors?

• Russia, South Korea, and Australia

• Germany, Brazil, and Canada

• France, India, Japan, Norway, and the United States

• Italy, Spain, and South Africa
