In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Correct! Well done.

Fusion requires temperatures of about 100 million degrees Celsius, approximately six times hotter than the centre of the sun.

Correct! Well done.

The emissions from the big towers you see at a nuclear power station is just water vapor. The cooling towers are part of the cooling water system used to condense steam from the turbine back into water.

Correct! Well done.

Thorium is an abundant element found in nature. Like Uranium, its properties allow it to be used to fuel a nuclear chain reaction that can run a power plant and generate electricity. Thorium itself will not split and release energy. Rather, when it is exposed to neutrons, it will undergo a series of nuclear reactions until it eventually emerges as an isotope of uranium called U-233, which will readily split and release energy next time it absorbs a neutron.

Correct! Well done.

Geothermal energy is the thermal energy in the Earth’s crust which originates from the formation of the planet and from radioactive decay of materials.

Correct! Well done.

When deuterium and tritium fuse, they create a helium nucleus, which has two protons and two neutrons. The reaction releases an energetic neutron. Fusion power plants convert energy released from fusion reactions into electricity to power our homes, businesses, and other needs.
