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 do you use nuclear Fusion?

Right now it can only be used in weapons, no fusion reactor experiment yet has even reached breakeven (releasing as much energy as was put in to start fusion). You must go well past breakeven to get usable power.


How much does a fusion reactor cost?

Nobody knows- they have not yet built a fully working fusion reactor.


How fast does a nuclear fusion reactor work?

Do you mean how much power does it produce? None are working as yet.


What are the main reasons why fusion reactions are not used in nuclear reactors?

No design of a fusion reactor has yet been able to reach what is called breakeven: the ability to make as much energy as it takes to operate the reactor. Until a prototype fusion reactor can make enough energy to operate itself, it is useless to even consider the uses of fusion reactions in possible power plants of the future.The temperature of a fusion reaction is not only high enough to melt any matter it touches but to vaporize that matter into a plasma! Therefore the reacting materials and their products must be confined in the reactor using forcefields not matter. We do not yet know how to make strong enough forcefields reliably.


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.


How much is a fusion reactor in world war?

ATTENTION SUPERVISORS: This question makes no sense.


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.


How much energy is lost during nuclear power producttion?

The efficiency of a PWR or BWR reactor power plant is about 33 percent, so this means that about 67 percent of the reactor's thermal output is rejected to the cooling water


How much uranium produces nuclear power?

The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.


How much energy is produced by a nuclear reactor?

For a typical fission reactor, power output can range from maybe 700 to 1000 MW (megawatts) with most modern deisgns being in the high end of that range.


How much plutonium is needed to run a reactor?

This depends on the type and power of the reactor; say tens of metric tons for a commercial reactor..
