The plasma in a fusion reactor needs to be very hot to achieve the high temperature and pressure conditions required to overcome the electrostatic repulsion between positively charged atomic nuclei and initiate the fusion reaction. This high temperature allows the atomic nuclei to collide with enough energy to overcome the electrostatic barrier and fuse together, releasing energy in the process.
What else can I help you with?
Why is it difficult to develop a fusion reactor for power generation?
Developing a fusion reactor for power generation is challenging due to the need to confine and control the extremely high temperatures and pressures required for nuclear fusion to occur. Additionally, managing the plasma within the reactor, handling the intense neutron radiation, and finding suitable materials that can withstand the harsh conditions present further obstacles. Research is ongoing to overcome these challenges and make fusion power a viable energy source.
Does plasma have a lot of energy?
Yes, plasma has a lot of energy because it is made up of particles that have been ionized, meaning they have high kinetic energy. Plasma can reach very high temperatures, making it a powerful source of energy for applications such as fusion research and plasma-based technologies.
An example of plasma?
The sun is an example of a natural plasma. Plasma is the fourth state of matter, consisting of charged particles that are highly energetic and capable of conducting electricity. In the sun, the high temperatures and pressures cause atoms to become ionized, creating a plasma that generates heat and light through nuclear fusion.
What is plazma physics?
Q: What is plasma physics? not plazma. A:Matter assumes the state of gas, comprising of ions and electrons, at a very high temperature. This is called plasma. The study of properties of matter in this state is called plasma physics.
Why do you use fission reactors not fusion reactors?
No way has yet been found to reach break-even in a controlled fusion reaction and get as much energy out as was needed to put in to start the reaction. To make a reactor you need to go past break-even and release extra energy.
Can you make a real ark reactor?
An Ark reactor as currently describe in comic is very much like a Nuclear Fuel Cell. Possibly convert energy from Nuclear reaction to power. Possibly a plasma nuclear fusion reactor. I believe in the future it could be made. See the link and compare the similarity of fusion reactor and Ark reactor.

How expensive is nuclear fusion?
At this time:in a bomb, very cheapin a reactor, not yet possible
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 are the technical problems related to nuclear fusion?
Nuclear fusion requires very high temperatures and immense pressures to start and continue. The problems with a nuclear fusion reactor would be:- 1) the high temperatures would melt the container: therefore, the reaction would have to be stored in a vacuum suspended by a magnetic field and the reactor would have to be continually cooled. 2) nuclear fusion occurs naturally in stars such as our sun: unless the fusion reaction was limited in size in some way, it would be likely that our planet is vapourised by the reaction.
What is plasma and how does it happen?
Referred to as a 4th state of matter, plasma is a very hot condition that occurs in stars in which electrons are no longer orbiting individual nuclei, this allows collisions of nuclei which may lead to nuclear fusion.
What gases are burning in are sun?
In the Sun hydrogen is converted to helium. Both are PLASMA. It's a very common misconception that the fusion in the sun happens with gas. However, the heat created by this fusion heats up the gasses so much that the individual electrons become loose from the atom. We call this state plasma.
Does plasma have a lot of energy?
Yes, plasma has a lot of energy because it is made up of particles that have been ionized, meaning they have high kinetic energy. Plasma can reach very high temperatures, making it a powerful source of energy for applications such as fusion research and plasma-based technologies.
Why isn't fusion used in the production of nuclear power?
Fusion is not used in the production of nuclear power, other than in the Sun and stars, due to technological problems, primarily in containment. The Sun has it easy, so to speak, because its large gravity and mass causes the temperature and pressure necessary to initiate and sustain fusion, while its gravity also eliminates the need for containment. Attempting to do this on the Earth would not work because the size of the reactor would vastly exceed the size of the Earth. The alternative, building a containment vessel, is not working because the many millions of degrees of heat required for the plasma would destroy any vessel we have. Building a magnetic containment vessel, such as the tokamak (ITER) shows promise, but the technical problems of having supercold magnets in close proximity to superhot plasma are very overwhelming. First fusion for this project is set for 2019, and my guess is that commercial power from fusion is at least 50 to 100 years away.
Why are fusion reactions difficult to recreate in a scientific laboratory?
Fusion reactions require extremely high temperatures and pressures to overcome the electrostatic repulsion between positively charged nuclei and achieve fusion. Controlling and sustaining these extreme conditions in a laboratory setting is a significant technical challenge. Additionally, the high-energy neutrons produced by fusion reactions can damage the materials used in the fusion reactor, posing another obstacle to recreating fusion in a controlled manner.
How fast does a nuclear fusion reactor work?
A nuclear fusion reactor works by creating high temperatures and pressures to fuse atomic nuclei together, releasing vast amounts of energy in the process. The reaction itself happens very quickly, with fusion reactions occurring on the order of microseconds. However, sustaining and controlling the reaction to generate continuous energy requires sophisticated equipment and technology.
Is hydrogen like plasma?
Yes, plasma is the fourth state of matter where the gas phase is heated to high temperatures, causing the atoms to ionize. Hydrogen can be in a plasma state at very high temperatures, such as in stars or during fusion reactions.
