Understanding Nuclear Fusion

What is the primary goal of developing nuclear fusion technology?

• To reduce the Earth's gravitational pull

• To replace solar energy

• To provide a limitless supply of clean energy

• To create a new form of nuclear weapon

What are the two types of hydrogen needed for nuclear fusion on Earth?

• Hydrogen and Oxygen

• Deuterium and Tritium

• Helium and Neon

• Carbon and Nitrogen

How does nuclear fusion differ from nuclear fission?

• Fusion splits atoms, while fission combines them

• Fusion is safer and produces less high-level waste than fission

• Fission is used in the sun, while fusion is used in power plants

• Fusion requires less energy input than fission

What is a major challenge that all types of fusion reactors face?

• Finding enough space for the reactors

• Generating more energy than is input

• Cooling the reactors efficiently

• Preventing the reactors from melting

What was the significant achievement of the JET experiment in February 2022?

• Achieving energy break-even

• Reaching 150 million degrees Celsius

• Generating enough energy to power a city

• Creating a self-sustaining fusion reaction

What is a potential solution to the tritium supply issue in fusion reactors?

• Using only deuterium for fusion

• Breeding tritium within the reactor

• Importing tritium from other planets

• Replacing tritium with helium

What is the expected timeline for fusion energy to significantly contribute to the power grid?

• By 2030

• Between 2060 and 2070

• By 2050

• Between 2100 and 2200

What is a major concern regarding the investment in nuclear fusion?

• The high cost of building reactors

• The uncertainty of achieving large-scale energy production

• The lack of interest from private investors

• The environmental impact of fusion

Why might some experts argue against investing heavily in fusion right now?

• Fusion is already a proven technology

• Fusion reactors are too small to be effective

• Renewables are a more certain solution for current energy needs

• Fusion technology is too simple

What is a positive outlook on the future of nuclear fusion?

• It will be the only source of energy by 2200

• It will replace all other forms of energy by 2050

• It will provide a solution for energy needs beyond 2100

• It will eliminate the need for solar panels
