Best Answer

Uranium or plutonium are usually used in fission reactors, although certain special reactor designs are capable of burning all of the transuranic elements too.

Depending on the reactor design this fuel can be packaged in a variety of different ways:

  • uranium oxide powder (aka "yellowcake" because of its color) canned in small zirconium alloy pellets (this is used in the largest number of reactors now operating)
  • short metal rods canned in zirconium alloy or aluminum alloy pellets
  • uranium oxide and/or plutonium oxide solid ceramic clad in porous carbon
  • a solution of uranium sulfate and/or uranium nitrate dissolved in water (this has the advantage of acting simultaneously as fuel, moderator, and coolant and as this liquid is continuously circulating through the reactor core it is possible to easily remove spent fuel, reprocess to obtain plutonium, and refuel without disturbing the reactor operation in any way; however it has the disadvantage that coolant in the primary cooling loop is very radioactive thus the heat exchanger must be shielded and inside the containment building)
  • etc.

What is a used fuel in nuclear power plants?

The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).

What is a Nuclear reactor moisture separator?

This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
