Why is nuclear fusion so difficult to achieve?
Nuclear fusion is difficult to achieve because it requires extreme conditions of temperature and pressure to overcome the repulsive forces between atomic nuclei. Additionally, containing and controlling the high-energy reactions involved in fusion is a major technical challenge.
Can plasma energy and atomic work together?
Plasma energy and atomic energy can work together in certain applications, such as in nuclear fusion reactors where plasma is used to confine and heat atomic nuclei to produce energy. However, they are distinct forms of energy with different properties and processes, so their compatibility depends on the specific technology and context in which they are used.
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.
Is fusion energy expensive?
"Expensive" is relative, since we have been unable to sustain a controlled break-even fusion reaction yet. So far, we have spent 10 billion euros attempting to do so, with another 100 billion budgeted in the next 50 years. If the theoretical concepts hold true, however, fusion power could well be the cheapest power on the planet.
What is the difference between a fission reactor and a fusion reactor?
In simplest terms, nuclear fission involves splitting atoms apart to make energy. Fusion involves smashing atoms together to make energy. Fusion reactors are currently entirely theoretical and do not exist. The main problem with fusion is figuring out how to get more energy out of the process than you put into making the fusion happen. Right now, the sun is the only place where fusion takes place on any meaningful scale.Another Answer:From a power production point of view, i.e. a controlledreaction, it is true that we have not been successful with fusion power. However, from a weapons point of view, i.e. an uncontrolled reaction, we have been successful. This is the basis of the hydrogen bomb. Interestingly, the hydrogen bomb requires so much energy to set it off that we use a fission bomb (the original atomic bomb) to initiate the fusion reaction.
Is it possible to contain plasma so it can be used as a weapon?
Not presently. We do not have a container for plasma. If we did, we would also have fusion reactors, which we do not.
Are there any fusion reactors operating now?
i believe they are still in the testing phases... but I have heard of one that was in operation not sure I would have to do some research again? So going on from here, Fusion reactors are still being tested small scale, and according to wikipedia, the worst source in the world. They are not expected to be used commercially untill atleast 2050.
What are ideal places for fission and fusion?
Fission takes place in nuclear reactors, which are useful to produce electricity. Fusion has not yet been harnessed on earth, so the only place it happens is in stars
How is the production of electricity by fission better than nuclear fusion?
In principle fusion should be better for the environment because it does not produce the active fission products. The snag is that it has not been made to work yet, and won't be for many years to come, so as a practical way of producing electricity it does not come into play, and we have to say fission is better than a non-existent fusion
Why are fusion reactors not yet present day reality like fission reactors?
Only beacuse of starting trouble. Any way we need billion kelvin temperature to start with for which we have to rely on fission reaction. One more important point we cannot have a controlled fusion reaction as we do so in fission ie nuclear reactor using control rods.
Does trap hole work on fusions?
A Fusion Summon, or the Summoning of any Monster (Synchro or Fusion) from the Fusion Deck (Extra Deck) is a special summon and so Trap Hole will not work on it.
What is the major disadvantage of using nuclear fusion reactors?
We don't have nuclear fusion reactors. We have not been able to sustain a controlled fusion reaction for more than a brief moment in time, and of more than a small amount of power. Only the Sun and stars have controlled fusion reactions, and Hydrogen bombs have uncontrolled fusion reactions. The problem is in maintaining the extremely high temperature and pressure required to sustain a fusion reaction, while at the same time containing the plasma that results from it. It is so hot that no container will hold it. We can build magnetic "bottles" so to speak, but the enormous flux required to do that requires super magnets, and that requires super-conductors and super-cold temperatures. Placing a super-hot plasma flow within the boundaries of a super-cold magnet is just not something we have accomplished yet. We are working on it, but, barring any stupendous discovery, I think controlled fusion reactors are at least 50 or a 100 years away.
How many years of nuclear power are left?
With fission reactors, probably at least a hundred years. By then fusion may be usable and this will last indefinitely, as so much deuterium is in the oceans.
Why is nuclear fusion so difficult to achieve?
Nuclear fusion is difficult to achieve because it requires extreme conditions of temperature and pressure to overcome the repulsive forces between atomic nuclei. Additionally, containing and controlling the high-energy reactions involved in fusion is a major technical challenge.
Why can't net fusion power be produced by linear particle acceleration?
Linear accelerators used in particle physics research are typically geared to accelerate a small amount of matter to extremely high energies. The energy required to do this is huge, but the energy gain not so. The trick in a fusion plant is not to achieve fusion, but to achieve a self-sustaining fusion reaction, like in the cores of stars, so that the output exceed the input.Particle accelerators may be used in fusion reactors to heat the plasma to temperatures required for fusion by neutral beam injection.
What is the current practical application of fusion?
The only current application of fusion is in fusion-type nuclear weapons. We cannot control fusion to use it in power sources, so we are limited to just a single use or application.
How would a fusion reactor differ from the nuclear reactors you currently have?
The nuclear reactors we have now are fission reactors. This means that they obtain their energy from nuclear reactions that split large nuclei such as uranium into smaller ones such as rubidium and cesium. There is a binding energy that holds a nucleus together. If the binding energy of the original large nucleus is greater than the sum of the binding energies of the smaller pieces, you get the difference in energy as heat that can be used in a power station to generate electricity. A fusion reaction works the other way. It takes small nuclei like deuterium (heavy hydrogen) and fuses them together to make larger ones such as helium. If the binding energy of the two deuterium nuclei is greater than that of the final larger helium nucleus, it can be used to generate electricity. There are two main differences between fission and fusion. The first is that the materials required for fission are rarer and more expensive to produce than those for fusion. For example, uranium has to be mined in special areas and then purified by difficult processes. By contrast, even though deuterium makes up only 0.02 percent of naturally occurring hydrogen, we have a vast supply of hydrogen in the water making up the oceans. The second difference is that the products of fission are radioactive and so need to be treated carefully, as they are dangerous to health. The products of fusion are not radioactive (although a realistic reactor will likely have some relatively small amount of radioactive product). The problem with building fusion reactors is that a steady, controlled fusion reaction is very hard to achieve. It is still a subject of intense research. The main problem is that to achieve fusion we need to keep the nuclei we wish to fuse at extremely high temperatures and close enough for them to have a chance of fusing with one other. It is extremely difficult to find a way of holding everything together, since the nuclei naturally repel each other and the temperatures involved are high enough to melt any solid substance known. As technology improves, holding everything together will become easier, but it seems that we are a long way off from having commercial fusion reactors.
