In the PWR the top houses the steam outlet, not inlet, and coolant flow is applied to the pressure vessel inlet connections.
A glass lined vessel would simply not be durable enough for a 40 or hopefully 60 year life. If it started cracking or peeling off, how would it be repaired?
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.
a reactor is generally termed as an autoclave reactor,when it is a high pressure batch reactor.mostly this kind of reactors are used for sterilization the reactants..
Probable you think to a breeder reactor; this type of nuclear reactor produce more fissile material than it consumes.
a smoothing reactor in dc circuits reduces harmonic currents in dc lines.
which material used in glassline reactors? What is glassline material ? Basic
The most common coolant used in nuclear reactors is water. There are light water reactors (using "regular" water), and the heavy water kind of reactor.
Coolant Systems on a Nuclear Reactor works by pumping large amounts of Sea Water into the reactors to cool it down and produce steam.
During normal operation, reactor coolant is not high radioactive. Otherwise it could not be transformed into steam that goes directly to turbines in Boiling Water Reactors.

Some early and some experimental reactors used sodium as the primary coolant.
Presumably you mean nuclear reactor coolant? This is the fluid that transfers the reactor thermal output to the steam raising units in a PWR, or to the turbine in a BWR, in which cases it is natural water. Gas cooled reactors can use carbon dioxide or helium, and CANDU reactors use heavy water.
All power reactors are thermal reactors except few ones that are fast nuclear reactors.
Water is used as coolant in most reactor plants to keep the reactor cool and prevent over heating. They do not necessarily need to be near a source of water; water just has to be available. However, a lot of nuclear reactors are build by a natural source of water so that the water can be used as an emergency source of coolant to keep the reactor covered with water in case of a rupture.
Many pressurized water reactors use "regular" water (light water) as a primay coolant. That means that "only heavy water" is not a rule as regards reactor design. Reactor design specifies the coolant to be used.
Nuclear reactors use coolants (a main coolant) to keep form overheating, of course. They are also used totransfer the thermal energy (heat) generated by a reactor to the steam generating units.

Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
