To make nuclear fusion a reliable energy source one day, scientists will first need to design heat- and radiation-resilient materials

Fusion energy has the potential to be an effective clean energy source, as its reactions
generate incredibly large amounts of energy. Fusion reactors aim to
reproduce on Earth what happens in the core of the Sun, where very light
elements merge and release energy in the process. Engineers can harness
this energy to heat water and generate electricity through a steam turbine,
but the path to fusion isn’t completely straightforward.

Controlled nuclear fusion has several advantages over other power sources for
generating electricity. For one, the fusion reaction itself doesn’t
produce any carbon dioxide. There is no risk of meltdown, and the reaction
doesn’t generate any long-lived radioactive waste. I’m a nuclear
engineer who studies materials that scientists could use in fusion
reactors.

Fusion takes place at incredibly high temperatures. So to one day
make fusion a feasible energy source, reactors will need to be built with
materials that can survive the heat and irradiation generated by fusion
reactions.
