Wigner effect
Well kiddo, do you know what happens when you play with play-doh for a really long time? It gets all mushy and eventually starts to break down and fall apart, right? That's kind of what the Wigner effect is all about.
When we use something called a nuclear reactor, we're basically playing with really tiny Lego blocks that make a lot of heat. And just like how play-doh can get mushy and fall apart over time, these tiny Lego blocks can also start to break down and become weaker over time, which can make the reactor less safe.
This process is called "radiation damage," and it happens because tiny particles called neutrons are bouncing around inside the reactor and hitting the Lego blocks, which can change their structure and make them weaker. The Wigner effect is specifically when these Lego blocks, which are actually called graphite bricks, start to change shape and become more brittle over time, which can make them more likely to break if there's a problem with the reactor.
So just like how you have to be very careful when playing with play-doh for a long time, scientists and engineers have to be very careful when using nuclear reactors to make sure they stay safe and don't break down. They constantly monitor the reactor and the graphite bricks to make sure everything is working properly and that the Wigner effect isn't causing any problems.
