Why the steam inlet at the top and coolant circulation from bottom of the reactor why we can't use the glass lined reactors for alkali reactions?

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?

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.
What is an autoclave reactor?
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..
What are feeder reactors?
Probable you think to a breeder reactor; this type of nuclear reactor produce more fissile material than it consumes.
What are smothing reactors?
a smoothing reactor in dc circuits reduces harmonic currents in dc lines.
Which material use in glass line reactor?
which material used in glassline reactors? What is glassline material ? Basic
How do coolant systems work in nuclear reactors?
Coolant Systems on a Nuclear Reactor works by pumping large amounts of Sea Water into the reactors to cool it down and produce steam.
Is a reactor coolant high radioactive?
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.

How sodium is used in nuclear reactor?
Some early and some experimental reactors used sodium as the primary coolant.
How are nuclear reactors used in nuclear reactors?
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
Why is sodium used as a coolant for nuclear reactors?
Sodium is used as a coolant in nuclear reactors because it has excellent heat transfer properties, allowing it to efficiently remove heat generated in the reactor core. It also has a high boiling point, which helps maintain stable coolant temperatures. Additionally, sodium does not moderate neutrons, which is important in certain reactor designs to prevent unwanted reactions.
What is a nuclear reaction 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.
Does liquid sodium is used as a coolant in nuclear reactors?
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.
What are the three main advantages of a fusion reactor compared to a fission reactor?
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.
Why is only heavy water used as coolant for nuclear energy and can you use any other coolant used replacing D2O?
Heavy water is used as a coolant in nuclear reactors because it is a good moderator, slowing down neutrons to sustain the nuclear chain reaction. While other coolants like light water or gas can be used in certain reactor designs, heavy water offers advantages in certain types of reactors, such as CANDU reactors. Other coolants can be used with modifications, but their effectiveness in moderating neutrons may vary.
How do you control nuclear reactors inside a nuclear reactor?
Nuclear reactors are controlled using control rods that absorb neutrons and regulate the rate of fission in the reactor core. By adjusting the position of these control rods, operators can manage the nuclear reaction and control the power output of the reactor. Additionally, coolant flow and reactor temperature are also monitored and adjusted to ensure safe and stable operation.
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.
