Mainly Plutonium fuel.
They are usually started on highly enriched uranium (i.e., weapons grade) fuel, with a breeding blanket of depleted uranium surrounding the core. Over time the breeding blanket is periodically changed and the old one reprocessed to extract plutonium; which is used to make replacement fuel for the reactor (and sometimes others). So the reactor starts on uranium fuel and each time the fuel is replaced it transitions gradually to plutonium fuel.
It is also possible to tune a breeder reactor to operate as a plutonium burner (without breeding new fuel). Such a reactor would burn plutonium only. This has been suggested as an effective means of disposing of the current "excess" of plutonium removed from retired nuclear weapons.
What else can I help you with?
Why moderator is not used in case of fast breeder reactor?
Moderator is not used in case of fast breeder reactor because there is no need to slow down neutron energy. Nuclear fission takes place at high energy of neutrons.
Which elements are used for nuclear reactors in India?
Uranium. There is some interest in using thorium in the future. Thorium cannot be used directly as fuel in a reactor as it does not fission, it requires a fast breeder reactor to convert it to Uranium-233 which does fission.
In a breeder reactor a. Plutonium is converted into uranium or b. Uranium is converted into plutonium?
Uranium. A breeder reactor can use either Uranium, Plutonium, or mixed Transuranic elements for fuel. Depleted Uranium or Thorium is used as the breeding blanket. Periodically the breeding blanket is changed: the old one reprocessed to make new fuel.
What element uses breeder reactor uranium or plutonium?
A breeder reactor uses uranium-238 or plutonium-239 as fuel. These elements can undergo fission reactions and produce additional fuel as a byproduct, making breeder reactors efficient in generating more nuclear fuel than they consume.
Does a breeder reactor use uranium as a fuel?
Yes, a breeder reactor uses uranium as a fuel. Specifically, it uses a specific isotope of uranium, such as uranium-235 or uranium-238, to sustain a nuclear chain reaction. The reactor can also produce more fissile material, like plutonium-239, through breeding reactions.
Which Fuel is used in Fast Breeder Reactor?
Fast Breeder Reactors typically use a combination of plutonium-239 and uranium-238 as fuel. This type of reactor produces more fissile material than it consumes, making it an efficient way to generate nuclear power.
Location of prototype fast breeder reactor?
The advantage is mainly that more active fuel can be created than is used, so getting 'something for nothing'. However experimental reactors such as the sodium cooled fast reactor at Dounreay in Scotland have proved very difficult in practice, with material problems, and as far as I know such experiments are in abeyance at the moment.
Why moderator is not used in case of fast breeder reactor?
Moderator is not used in case of fast breeder reactor because there is no need to slow down neutron energy. Nuclear fission takes place at high energy of neutrons.
What is the coolant used in kalpakkam power station in India?
Kalpakkam has both Thermal reactor (Madras Atomic Power Station) and Fast Breeder Reactor -FBTR and PFBR (Under construction). In MAPS (thermal reactor) it is Heavy Water (D2O) Which acts as a coolant as well as moderator, where as in Fast Breeder Test Reactor (FBTR) and Prototype Fast Breeder Reactor (PFBR) Sodium (Na) is used as coolant. Since there should not any moderators for fast reactors D2O will not be used as coolant in fast reactors.
Which type of pump is used to pump liquid metal in fast breeder reactor?

Which elements are used for nuclear reactors in India?
Uranium. There is some interest in using thorium in the future. Thorium cannot be used directly as fuel in a reactor as it does not fission, it requires a fast breeder reactor to convert it to Uranium-233 which does fission.
What is done with the Pu 239 from a fast breeder reactor?
The idea is to use it for nuclear fuel in other reactors, this is why it is called a breeder process. Uranium-238 which is not fissile is converted to Pu-239 in the breeder reactor, but of course there is a chemical separation process to go through before the Pu is available.
How does one use a breeder reactor?
It would be used as a more efficient version of a Nuclear Reactor. While a regular nuclear reactor requires almost a factor of 100 greater in fuel amounts, a Breeder reactor uses much less and produces less waste.
In a breeder reactor a. Plutonium is converted into uranium or b. Uranium is converted into plutonium?
Uranium. A breeder reactor can use either Uranium, Plutonium, or mixed Transuranic elements for fuel. Depleted Uranium or Thorium is used as the breeding blanket. Periodically the breeding blanket is changed: the old one reprocessed to make new fuel.
What is produced from uranium-238 in a breeder reactor?
In a breeder reactor, uranium-238 absorbs a neutron and transmutes into plutonium-239, which is a fissile material that can sustain a nuclear chain reaction. This plutonium-239 can then be used as fuel in the reactor to produce energy.
Why moderator is not use in bleeder reactor?
Moderators are not used in a breeder reactor because their primary purpose is to slow down neutrons to increase the likelihood of fission events in a thermal reactor. In a breeder reactor, fast neutrons are required to convert non-fissile uranium-238 into fissile plutonium-239, so using a moderator would hinder this process.
What element uses breeder reactor uranium or plutonium?
A breeder reactor uses uranium-238 or plutonium-239 as fuel. These elements can undergo fission reactions and produce additional fuel as a byproduct, making breeder reactors efficient in generating more nuclear fuel than they consume.
