Hello today we are going to a nuclear plant to see how nuclear energy works.
We already learned this why learn again?
The isotope U-235 is important because under certain conditions it can readily be split, yielding a lot of energy. It is therefore said to be 'fissile'. Meanwhile, like allradioactive isotopes, it decays.
Uranium-238 decays too slowly, but you have to take the uranium-238 out of the ore to get the Uranium-235 also known as enriched ore.
Why don't nuclear plants use U-238? since it is more common.
The control rods, made of Boron, are used to control the speed of the reaction by soaking up the neutrons. The fuel rods bring the uranium into the water. and when you remove the control rods the process proceeds.
During nuclear fission, a neutron collides with a uranium atom and splits it, into Barium, krypton, and 3 neutrons are produced, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits. These neutrons continue to collide with other uranium atoms, and the process repeats itself over and over again.
But what about the fuel rods and control rods Mr. Moton?
Mr. Moton how does any of this make eneregy?
the process of nuclear fission generates heat to produce steam, which is used by a turbine generator to generate electricity. When the turbine turns the generator turn. All that energy goes to the grid.
So nuclear plants cannot get rid of all the U-238 so when a neutron hit U-238 it turns into Plutonium, which is way more radioactive than uranium, also creating nuclear waste.
