Making the heart of a star power the world

What is the main difference between nuclear fusion and nuclear fission?

• Both fusion and fission split atoms.

• Both fusion and fission combine atoms.

• Fusion combines atoms, while fission splits them.

• Fusion splits atoms, while fission combines them.

Why is nuclear fusion considered a cleaner energy source compared to fission?

• It produces more carbon emissions.

• It produces less radioactive waste and no carbon emissions.

• It generates more radioactive waste.

• It requires less energy input.

What was the significant achievement at the JET facility in February?

• They sustained a fusion reaction for 101 seconds.

• They produced 59 mega joules of energy in a fusion experiment.

• They produced 1.3 mega joules of energy.

• They achieved a net positive energy output.

Which country recently managed to sustain a fusion reaction at 120 million degrees for 101 seconds?
