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.
It could be used with light water reactors.

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

Yes, they are fast nuclear reactors
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.

Liquid sodium has been used as a coolant in fast reactors, because it does not slow down and absorb fast neutrons. It does not control the nuclear reaction directly, for that variable neutron absorbers are required.
a moderator would slow the neutrons, hindering breeding
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.
Yes, liquid sodium is used as a coolant in some types of nuclear reactors, known as sodium-cooled fast reactors. These reactors use liquid sodium to transfer heat away from the reactor core, which helps generate electricity. Sodium's high heat capacity and low neutron absorption make it an effective coolant for these types of reactors.
Uranium-238 has only one disadvantage: it is not a fissile material with thermal neutrons.But it is a fertile material good for some types of reactors or can be used in reactors with fast neutrons.
