What is the temperature of nuclear fuel in a fission reactor?
In water reactors, PWR and BWR, the fuel itself is in the form of tubes about 10mm diameter, filled with UO2 fuel and clad in zircaloy sheathing. It is important to avoid melting of the sheath, which...

What does the moderator do in a nuclear fission reactor?
The moderator is there to slow down the neutrons produced by fission. These are produced with high energy, that is they move fast, but Uranium235 has a capture cross section much greater for slow...

What is needed in a nuclear fission reactor?
A fissionable material that is self-sustainable on a practical level (like U-235), a material to slow down the neutrons caused by the fission (like water), a material to control the chain reaction by...
