Which is an advantage of thorium nuclear fission over uranium nuclear fission?

• Has a freeze plug safety shut-off.

• Emits no air pollution.

• Emits no greenhouse gases.

• Is useful for making nuclear bombs.

Which is easier, cheaper, and safer to mine and process for nuclear fission?

If we emit too much greenhouse gases, like carbon dioxide (CO₂) and methane (CH₄), which is not true?

• Most of earth will overheat.

• Many Americans will migrate to cooler Canada.

• Earth will have another mass extinction event.

• More people will wear coats in the summer.

If an accelerator-driven thorium nuclear fission reactor loses electricity for its thermostat and controls, ____. Choose all correct answers.

• It melts out of control and then explodes, leaking out radioactive poisons.

• Its required neutron beam turns off, which shuts off the reactor.

• A cooling fan turns off, so the liquid fluoride thorium salt melts and drains out, which stops the reactor.

• It splits its cooling water into hydrogen and oxygen, which explode, causing a leak of dangerous radioactive poisons.

Which of the following was not a nuclear disaster?

• Chernobyl

• Three Mile Island Partial Meltdown

• Fukushima Daiichi

• Lawn Lake Dam
