nuclear fission makes energy

An example of public science dialogue likely to encourage alternative conceptions:

"So uranium is made out of a number of different isotopes. Isotopes are just different atoms with different masses. So, there's two major isotopes of uranium, that's uranium 2-35 and uranium 2-38, and uranium 2-35 is the one that fissions, that if you hit it with a neutron it splits and it makes energy. And the other one doesn't, the other one doesn't do anything. So you typically want to enrich it for a nuclear reactor, to make it make energy, you want to make the 2-35 number go up, and that's what you do in an enrichment facility. They can do that in a number of ways, but the way that it is normally done is via a centrifuge which spins it round and round and round like a merry-go-round…The Zaporizhzhia plant is a fission plant so they're actively sort of splitting those uranium atoms up inside that reactor to make energy."

Professor Simon Middleburgh (School of Computer Science & Engineering, Bangor University) was interviewed on an episode (What happens when you bomb a uranium enrichment site?) of BBC Inside Science.
