Residuos nucleares

The video discusses induced nuclear fission, a process that splits an atom's nucleus to produce energy, resulting in smaller, unstable nuclei called radioisotopes. It highlights the challenges of managing radioactive waste, which can remain hazardous for thousands of years. The video explains the disposal methods, including cooling pools and solidification with glass composites, and the potential for reusing spent nuclear fuels. However, it also warns of the dangers associated with reused fuels, such as the production of plutonium. The video concludes by questioning the sustainability of nuclear energy due to the long-term risks of waste disposal and plant decommissioning.

What is produced when an atom's nucleus is split during nuclear fission?

• Greenhouse gases

• Radioisotopes

• Nuclear weapons

• Stable atoms

How is liquid radioactive waste typically made safer for storage?

• By diluting it with water

• By mixing it with glass composites

• By burning it

• By burying it in the ocean

What is a potential benefit of reusing spent nuclear fuel?

• It eliminates the need for nuclear plants

• It generates more high-level waste

• It produces more greenhouse gases

• It reduces the amount of waste produced

What is a major component of nuclear weapons that is also produced by reused nuclear fuel?

• Uranium

• Radon

• Plutonium

• Thorium

What is a significant concern regarding the long-term use of nuclear energy?

• The safe disposal of nuclear waste

• It is not a reliable energy source

• It is too expensive to produce

• It produces excessive greenhouse gases
