A Tokamak reactor uses strong magnetic fields to contain the fusion reaction. While significant progress has been made in the field of fusion, temperatures high enough for continuous fusion have not been sustained for long periods of time. (Chemistry: Matter and Change; book)

Where is heat from a nuclear reactor transferred to in the cooling system?
Heat from a nuclear reactor is transferred to the cooling system, where it is carried away by water or another coolant to prevent the reactor from overheating.
What part of the nuclear reactor is the fuel located in?
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
What is core of nuclear reactor?
In the PWR and BWR types it is a matrix of fuel assemblies stabilised with zircaloy fittings, and with control rods in certain specified channels within this matrix. This is where the nuclear heat is generated, and this heat is carried away by a flow of very pure water circulated by large pumps and at a high pressure.
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.
When should decay heat be removed from the reactor core to prevent fuel damage?
Decay heat should be removed from the reactor core as soon as possible after the reactor is shut down to prevent fuel damage. If the heat is not removed, it can cause the fuel to overheat and potentially result in damage to the fuel rods, leading to a meltdown. Cooling systems such as circulating water or coolant are used to remove the decay heat from the reactor core.
Why do nuclear fuel rods heat in a reactor that is shut down?
Because the fission products that are contained in the fuel are radioactive and produce a substantial amount of heat.
What substance is used in a nuclear reactor to absorb heat released from the reactor?
Coolant, such as water or a specific type of liquid metal, is used in a nuclear reactor to absorb the heat released during the nuclear fission process. The coolant carries away the heat and helps to regulate the temperature within the reactor to prevent overheating.
A reactor and uranium are used in the production of .?
A reactor and uranium are used in the production of nuclear energy. Uranium undergoes a process called nuclear fission within the reactor, where atoms split and release energy in the form of heat. This heat is then used to generate electricity through steam turbines.
What is the function of baffles in a chemical reactor?
Baffles in a chemical reactor serve to improve mixing and promote uniform distribution of reactants. They help prevent swirling or vortex formation, which can affect the reaction rate and efficiency. Baffles also assist in dissipating heat and enhancing heat transfer within the reactor.
Where is heat from a nuclear reactor transferred to in the cooling system?
Heat from a nuclear reactor is transferred to the cooling system, where it is carried away by water or another coolant to prevent the reactor from overheating.
What limits scientists from downsizing the tokamak reactor?
Scientists are limited in downsizing tokamak reactors due to the need for a certain magnetic field strength to confine the plasma, control instabilities, and sustain fusion reactions. Additionally, scaling down the size of the reactor can lead to challenges in maintaining high plasma temperatures and controlling heat and particle loads on the materials. Researchers are actively exploring new designs and technologies to overcome these limitations for potential future reactors.
What does a nuclear reactor heat?
Water.
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 purpose a nuclear reactor?
To produce heat.
What is a star and how are they classified?
A star is a large, naturally occurring fusion reactor. Stars are classified by size, content, heat, and position within life cycle.
How do you do an energy balance for a cs-tr?
To perform an energy balance for a CSTR (continuous stirred-tank reactor), you need to account for the energy input (heat, work) and output (cooling, agitation losses, heat exchange with surroundings) in the system. The energy balance equation typically involves the heat generated or consumed in the reaction, the heat capacity of the reactor contents, and the temperature changes within the reactor. By summing up these energy terms, you can determine the overall energy balance for the CSTR system.
How does a nuclear reactor eliminate heat?
Heat is eliminated through use of reactor coolant passing over the nuclear fuel in the primary coolant loops.
