Most reactors use water as a coolant, but many other materials have been used:
- liquid metals like Lithium, Sodium, Potassium, Mercury, Lead, etc.
- gasses like Helium, Air, Carbon Dioxide, etc.
- hydrocarbons like Oil, Paraffin, Diphenyl, etc.
- etc.
A few reactors have been built using liquid slurry fuel, where the fuel is both fuel and coolant at the same time. Such reactors do have the problem that the primary cooling loop and primary heat exchanger must be heavily shielded.

How much coolant is used in a nuclear power reactor?
The amount of coolant used in a nuclear power reactor can vary depending on the design of the reactor. Generally, a nuclear power reactor may use thousands to millions of gallons of water or a different coolant material to remove heat generated during the nuclear fission process. The coolant circulates through the reactor core to transfer heat and help regulate the temperature of the reactor.
What is the purpose of the reactor vessel?
The reactor vessel is the main container that houses the nuclear fuel, control rods, and coolant in a nuclear reactor. Its purpose is to contain and shield the nuclear reactions happening inside, and to provide structural support and safety for the reactor core.
What is the part of a nuclear reactor called where the nuclear reaction takes place?
The part of a nuclear reactor where the nuclear reaction takes place is called the reactor core. It typically contains the fuel rods, control rods, and coolant necessary for sustaining and controlling the nuclear reaction.
Name one type of nuclear reactor?
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
What is the function of the pressure vessel of a nuclear reactor?
The pressure vessel of a nuclear reactor contains the reactor core and helps to maintain a high pressure environment to prevent coolant water from boiling. It also serves as a barrier to contain radioactive materials and provide structural support for the reactor.
What type of coolants is usually used to remove heat from a nuclear reactor core?
Water is the most common coolant used to remove heat from a nuclear reactor core. In pressurized water reactors (PWRs), water is used both as a coolant and as a moderator.

What is the name of the coolant used in a pressurized water reactor?
The coolant used in a pressurized water reactor is typically purified water. This water is pressurized to prevent it from boiling and is circulated through the reactor core to remove heat generated during the nuclear reaction.

The reactor vessel is the main container that houses the nuclear fuel, control rods, and coolant in a nuclear reactor. Its purpose is to contain and shield the nuclear reactions happening inside, and to provide structural support and safety for the reactor core.
What are the functions of pressure vessel and turbine in a nuclear reactor?
The pressure vessel contains the reactor core with its fuel, coolant, moderator, control elements, and emergency systems. The turbine is the device that on receiving the steam it spins and turns the electric generators to produce electricity.
What is the part of a nuclear reactor called where the nuclear reaction takes place?
The part of a nuclear reactor where the nuclear reaction takes place is called the reactor core. It typically contains the fuel rods, control rods, and coolant necessary for sustaining and controlling the nuclear reaction.
Can you increase the thermal power of a nuclear reactor without changing the core of the reactor?
Yes, we can increase the thermal power of a nuclear reactor without changing the core of the reactor; primarily by:increasing the coolant mass flow rate,modifying the control rod patterns, andupgrading the turbo generator system

Why is a coolant important in a nuclear reactor?
Coolant is important in a nuclear reactor to transfer heat away from the reactor core, preventing it from overheating. It helps regulate the temperature within safe limits by absorbing and removing the heat generated during the nuclear fission process. Additionally, coolant also serves to slow down neutrons to facilitate efficient fission reactions.
What is the function of the pressure vessel of a nuclear reactor?
The pressure vessel of a nuclear reactor contains the reactor core and helps to maintain a high pressure environment to prevent coolant water from boiling. It also serves as a barrier to contain radioactive materials and provide structural support for the reactor.
Can a power plant can explode like a nuclear weapon?
No, a nuclear weapon needs a specific geometry to detonate, and it has to be held in this position by very high explosives to keep it in this shape. In a nuclear reactor, if the reactor core goes critical then the force of the expanding coolant will blow the reactor apart, preventing a nuclear blast.
What is the function of reflector and reactor core?
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
