What else can I help you with?
Does a breeder nuclear reactor use moderator?
No, a breeder nuclear reactor does not typically use a moderator. Breeder reactors are designed to produce more fissile material than they consume by using fast neutrons to convert non-fissile isotopes into fissile ones without slowing down the neutrons.
Is power reactor a thermal reactor?
Yes, a power reactor is a type of thermal reactor. Power reactors use nuclear fission to produce heat, which is then used to generate electricity. The heat generated in the reactor comes from the controlled chain reaction of nuclear fission, making it a thermal reactor.
Why is plutonium in a nuclear power sation?
Plutonium is used in nuclear power stations as a fuel in some types of reactors, like fast breeder reactors. It can undergo fission to produce energy. Additionally, plutonium can be created as a byproduct in nuclear reactors, which can then be reprocessed and reused as fuel.
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.
How is plutonium used in nuclear reactors?
Plutonium is used in nuclear reactors as a nuclear fuel (as dioxide, carbide or MOX). The isotopes 239Pu and 241Pu are fissionable with thermal neutrons; other isotopes are fissionable only with fast neutrons.
Is moderation of neutrons always used to slow nuclear fission?
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
What two metals are used as nuclear fules?
Two common metals used as nuclear fuels are uranium and plutonium. Uranium is the most widely used fuel in nuclear reactors, while plutonium is used as a fuel in some types of reactors, such as fast breeder reactors.
Does plutonium use for fuel nuclear?
Yes, plutonium is used as a fuel in nuclear reactors, specifically in certain types of reactors like fast breeder reactors and some types of advanced reactors. Plutonium-239, which is produced from uranium-238 in nuclear reactors, is a key fuel component due to its ability to sustain fission reactions.
What has the author W E Kastenberg written?
W. E. Kastenberg has written: 'Anticipated transients without scram for light water reactors' -- subject(s): Safety measures, Nuclear reactors, Liquid metal fast breeder reactors
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.
What reactors produces heat and a new supply of the radioactive isotope Pu-239?
Breeder reactors are designed to produce both heat and Pu-239 as a byproduct. These reactors use fertile material such as uranium-238 to breed plutonium-239 through neutron capture, resulting in a self-sustaining chain reaction. The produced Pu-239 can then be used as fuel in nuclear reactors or for nuclear weapons.
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.
