Understanding Nuclear Fission in Power Plants

AI Thread Summary
Nuclear fission in power plants begins when fuel rods are submerged in coolant water, which moderates the fission process. The arrangement of fuel rods initiates a chain reaction, while control rods manage the reaction rate by absorbing neutrons. The heat generated from fission produces steam, which drives a turbine connected to an industrial generator that produces electricity. Some of this electricity is used to power the plant itself. Various coolants and moderators can be employed, indicating flexibility in reactor design.

So I need some help verifying this information.(I had to dumb it down, for the younger ones) -

The Nuclear Fission process is started when the Nuclear fuels rods are submerged in coolant water to moderate the Nuclear fission process. When the Fuel rods are put close together this sets of a Nuclear fission. The Control rods are used to contain the Nuclear fission. The control rods are raised to increase energy output and are lowered to decrease energy output. The Nuclear fission naturally has a heat output. The heat is used to generate steam. The steam is used to turn a steam turbine, which turns the Industrial grade generator. The industrial grade Generator produces electricity which gives power to whatever they are diverting it to. Some of the electricity is siphoned off to use as power for the power plant.

It all depends on who your target audience happens to be.
The basis of the fission reaction is that the neutrons from one nucleus cause a chain reaction as they hit other nuclei.
The action of the moderator is to slow the neutrons down and to increase the probability of collisions and, thus, the chain reaction; that's a sophisticated idea but important. The control rods adjust the rate of the reaction by absorbing the neutrons. etc. etc.
Water is not always the coolant and nor is is always the moderator. Many combinations have been tried.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
