Will ITER break even?

Assuming the same η_heat = 0.7 and η_elec = 0.4, ITER (in theory) could produce as much as 112 MW of heating. This means ITER would operate at engineering breakeven.

Will ITER be successful?

Although the successful operation of ITER, still more than 6 years away, will be considered a major breakthrough for fusion energy, the new road map from the European Fusion Development Agreement (EFDA) includes a daunting list of the technical hurdles that fusion scientists and engineers still face over the next few ...

Is ITER a failure?

This, together with our incomplete knowledge of what to expect in the thermonuclear regime, makes ITER a risky project, whose failure could cause irreparable harm to the credibility of nuclear fusion.

Will ITER be self sustaining?

ITER, which will be completed in 2019 and ready for full-scale testing in 2026, will be closer to a functioning fusion generator but will not produce a self-sustaining fusion reaction.

How close is ITER to being done?

The reactor was expected to take 10 years to build and ITER had planned to test its first plasma in 2020 and achieve full fusion by 2023, however the schedule is now to test first plasma in 2025 and full fusion in 2035.

Former fusion scientist on why we won't have fusion power by 2040

Can ITER explode?

"A nuclear explosion in ITER is simply not possible," says Loughlin. Loughlin went on to address the subject of radioactivity. During fusion, neutrons escape the plasma at high speeds and activate the surrounding walls.

Will ITER produce electricity?

ITER is designed to produce a ten-fold return on energy (Q=10), or 500 MW of fusion power from 50 MW of input heating power. ITER will not capture the energy it produces as electricity, but—as first of all fusion experiments in history to produce net energy gain—it will prepare the way for the machine that can.

Is fusion still 20 years away?

Yet net gain in fusion, as the old joke goes, is always 10 to 20 years away, no matter what year it is. Or, as Galchen puts it, paraphrasing the White Queen in Lewis Carroll's Through the Looking Glass, “It is never jam today, it is always jam tomorrow.”

Why fusion is impossible?

On earth, we need temperatures exceeding 100 million degrees Celsius and intense pressure to make deuterium and tritium fuse, and sufficient confinement to hold the plasma and maintain the fusion reaction long enough for a net power gain, i.e. the ratio of the fusion power produced to the power used to heat the plasma.

Why is fusion power Impossible?

stars get all that energy "for free" by having massive, crushing levels of stellar gravity. we don't have that level of gravity available Earthside, therefore it's not even theoretically possible to build a viable fusion power plant.

Will ITER produce nuclear waste?

No long-lived waste

Fusion reactors, unlike fission reactors, produce no high activity/long life radioactive waste. The "burnt" fuel in a fusion reactor is helium, an inert gas.

Will nuclear fusion ever work?

It is expected to be the last step in proving nuclear fusion can become a reliable energy provider in the second half of this century. Operating the power plants of the future based on fusion would produce no greenhouse gases and only very small amounts of short-lived radioactive waste.

How much has ITER cost?

ITER is now expected to cost at least $21 billion and won't turn on until 2020 at the earliest. And a recent review slammed ITER's management. The cost of the U.S. contribution has increased, too, although by how much has been unclear.

Why is fusion taking so long?

In a fusion reactor, the plasma needs to be heated to at least 100 million degrees and forced to collide using electromagnets. Sadly, plasma is unstable and unpredictable, so the all-important collisions are difficult to force.

What is the status of the ITER fusion power project?

A partnership between the United States, Europe, Russia, India, Japan, China, and South Korea, ITER is scheduled to start operations in 2025, although it won't be fueled with the power-producing isotope tritium until 2035.

Why can't we make a fusion reactor using gravity?

Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.

Is fusion safer than fission?

Is Fusion or Fission More Dangerous? Nuclear fission is more dangerous than fusion as it produces harmful weapons-grade radioactive waste in the fuel rods that need to be stored safely away for thousands of years.

Is nuclear fusion getting closer?

Fusion is creeping inexorably forward and we are getting closer and closer to achieving that once distant dream of commercial fusion power. One day, it will provide a near limitless supply of low-carbon power for many future generations to come. So while it is not quite there yet, it is coming.

Is UK building a fusion reactor?

UK scientists set new record for generating energy from nuclear fusion with reaction '10 times hotter than the sun' The Joint European Torus is an experimental fusion machine in Oxford. Professor Ian Chapman said the results of the latest tests are a "landmark".

What is ITER tokamak?

The ITER Tokamak

The tokamak is an experimental machine designed to harness the energy of fusion. ITER will be the world's largest tokamak, with a plasma radius (R) of 6.2 m and a plasma volume of 840 m³.

Will ITER produce more energy than it consumes?

Although all fusion reactors to date have produced less energy than they use, physicists are expecting that ITER will benefit from its larger size, and will produce about 10 times more power than it consumes.

Could a fusion reactor melt down?

No risk of meltdown: A Fukushima-type nuclear accident is not possible in a tokamak fusion device. It is difficult enough to reach and maintain the precise conditions necessary for fusion—if any disturbance occurs, the plasma cools within seconds and the reaction stops.

Can fusion reactors melt down?

No, because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures with the support of external heating systems and confined by an external magnetic field.

Could a fusion reactor create a black hole?

So in short: No. Nuclear fission cannot generate black holes. Nor could nuclear fusion reactors (if they ever become feasible). However, micro-black holes ARE possible (in theory), but if one did form, it wouldn't be able to do any damage to Earth.

Is nuclear fusion cheap?

Electricity generated through fusion has no emissions, minimal waste, and there is no risk of out-of-control meltdowns like Chernobyl. The fuel, derived from helium or hydrogen, is cheap and plentiful. That's the theory.
