Okay, here's a slightly more technical explanation:

In a nuclear fission reactor, atoms of a radioactive element like uranium are bombarded with neutrons. This causes the uranium atoms to split apart or 'fission', releasing energy as well as more neutrons. The released neutrons then go on to split more uranium atoms, resulting in a controlled chain reaction. The energy is used to heat water into steam, which then spins a turbine to generate electricity. The byproducts of the fission reaction are radioactive waste products which must be safely stored or disposed of. So the key steps are: fission reaction -> heat generation -> water boiling -> turbine spinning -> electricity generation. But it all starts with initiating the fission chain reaction in the radioactive material. Now, you may have heard of nuclear energy before, and you might even know that it comes from splitting atoms. Well, that's exactly what we do in a nuclear fission reactor.

So, let me break it down for you. Atoms are the tiny building blocks that make up everything around us. Every atom has a nucleus in the center, which is made up of even smaller particles called protons and neutrons. In nuclear fission, we take a special type of atom called a uranium atom and we split it in two by shooting tiny particles at it.

When we split the uranium atom, it releases a lot of energy in the form of heat. This heat is used to turn water into steam, and that steam can then be used to turn turbines, which generate electricity. It's kind of like a big, high-tech steam engine!

But, nuclear fission can be dangerous if not handled properly. That's why we have special safety procedures and systems in place to make sure that everything is under control. It's important to make sure that the reactor is always being watched and monitored so that everyone stays safe.

So, there you have it - a quick rundown of nuclear fission reactors. They are a powerful source of energy that can help us create electricity in a clean and efficient way. But, we need to make sure that we use them responsibly and safely.
