Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.

Does a breeder nuclear reactor use moderator?
Thermal Breeder Reactors use moderators but Fast Breeder Reactors don't use moderator.
Is power reactor a thermal reactor?
All power reactors are thermal reactors except few ones that are fast nuclear 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.
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.
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 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.

Can a reactor without moderator is present?
Yes, they are fast nuclear reactors
What solutions have been found for nuclear energy?
Solutions? The most effective way to use nuclear power yet found is the PWR, with BWR a close second. These work well, but more advanced solutions will be developed in the future, like fast breeder reactors and fusion.
Why fast neutrons are not captured by nucleus?
The nucleus is very small; if it were the size of a golf ball the outer electrons would be about as far away as the height of the empire state building. If a neutron was moving very fast it probably wouldn't hit a nucleus. When , occasionally, a neutron does hit a nucleus, it might start nuclear fission- especially when the nucleus is heavy like Uranium 235 (U-235). So, to sum it up, most neutrons are not captured by a nucleus because they are both so small relative to the space that they are in, but sometimes a neutron will hit a nucleus.
