What type of coolant is used to remove heat from a nuclear reactor core?
Wiki User
∙ 12y ago
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.

Where is the nuclear energy produced in a nuclear reactor?
In the core.
What is in the core of a nuclear reactor?
The core of the nuclear reactor includes:nuclear fuel elements (composed of the fuel meat covered with cladding)reactor coolantreactor moderator (for thermal reactors)control elementsmeasuring instrumentsstructural and support structures
The part of a nuclear reactor in which the fuel is located is called the?
core
What is layer of lead around the core of a nuclear reactor?
Blanket
How is electricity made at a nuclear powerstation?
Electricity is made at a nuclear power station by creating a controlled nuclear chain reaction, fission, in the reactor core. This fission process generates heat, lots of it, due to the release of binding energy resulting from the loss of mass in the core. A coolant, usually water, keeps the temperature from reaching excessive levels. In the BWR (Boiling Water Reactor) that coolant flashes to steam. In the PWR (Pressurized Water Reactor) that coolant heats other coolant which flashes to steam. The steam spins a turbine / generator which makes electricity. The steam, which has now been condensed back to water by the turbine and condensor is reheated and fed back to the core (BWR) or steam generators (PWR) to repeat the cycle.
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
Where is the nuclear energy produced in a nuclear reactor?
In the core.
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 type of coolants is usually used to remove heat from a nuclear reactor core?
liquid sodium or water
Parts of nuclear reactor where nuclear fission occurs?
core
Why does the core of the reactor have a moderator?
The core of the reactor contains the nuclear fuel. Having a moderator in place within the core ensures that the nuclear fuel is processed at an accurate time duration. This can prevent serious problems from occurring within the entire nuclear reactor.
What part of a nuclear reactor would most likely contain plutonium?
This part is the core of the nuclear reactor containing the nuclear fuel.
The core of a nuclear reactor includes?
Fissionable substances.
