Understanding Nuclear Fusion and ITER

What does the acronym ITER stand for?

• International Thermonuclear Experimental Reactor

• International Thermal Energy Reactor

• Integrated Thermonuclear Energy Research

• Innovative Thermonuclear Energy Reactor

How does nuclear fusion differ from nuclear fission?

• Both fusion and fission split atoms

• Fusion combines atoms, while fission splits them

• Fusion splits atoms, while fission combines them

• Both fusion and fission combine atoms

What is the main goal of achieving fusion ignition?

• To create a new type of nuclear weapon

• To split atoms more efficiently

• To create a sustainable reaction that produces more energy than it consumes

• To reduce the cost of nuclear energy

What shape is a tokamak designed in?

• Rectangular

• Donut-shaped

• Cylindrical

• Spherical

What is the role of the Joint European Torus (JET) in relation to ITER?

• JET is a competitor to ITER

• JET is unrelated to ITER

• JET is a scaled-down version of ITER used for testing

• JET is a larger version of ITER

What are the two heavy versions of hydrogen used in fusion experiments?

• Deuterium and Tritium

• Tritium and Helium

• Tritium and Oxygen

• Deuterium and Helium

Why is tritium considered rare and challenging to work with?

• It is highly toxic

• It is expensive to produce

• It decays quickly and is rare in nature

• It is abundant but unstable

What is a key goal of the experiments at JET involving tritium?

• To reduce the cost of nuclear energy

• To understand the plasma dynamics in a D-T reaction

• To eliminate the use of deuterium

• To create a new type of nuclear weapon

What is a potential benefit of using tritium in fusion reactions?

• It produces fewer neutrons

• It has a lower energy yield

• It can help produce more tritium for future experiments

• It is easier to handle than deuterium

What is the ultimate dream of achieving fusion ignition?

• To reduce the cost of nuclear energy

• To produce a nearly limitless supply of clean energy

• To eliminate the use of nuclear reactors

• To create a new type of nuclear weapon
