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.

What does ITER stand for?

Iter, which stands for International Thermonuclear Experimental Reactor, is a major international project to build a 500MW tokamak fusion device (requiring an input of 50MW) designed to prove the feasibility of fusion as a large-scale and carbon-free source of energy.

How much does the ITER tokamak cost?

ITER estimates the cost of design and construction at about 20 billion euros (currently about $22 billion).

What is ITER Upsc?

International Thermonuclear Experimental Reactor (ITER) is a nuclear fusion power plant. This article will provide information about International Thermonuclear Experimental Reactor (ITER) in the context of the IAS Exam. This topic is useful for GS Paper II and GS Paper III of the UPSC Syllabus.

What is a tokamak Upsc?

The energy was produced in a machine called a tokamak, a doughnut-shaped apparatus. A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus.

ITER: The $65BN Power Plant of the Future

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 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 ITER still under construction?

The ITER Project is currently under construction on a 180-hectare site in southern France. Thirty-nine buildings and technical areas house the ITER Tokamak and its plant systems.

How does a tokamak work?

In a tokamak, magnetic field coils confine plasma particles to allow the plasma to achieve the conditions necessary for fusion. One set of magnetic coils generates an intense “toroidal” field, directed the long way around the torus.

How big is a tokamak?

830 cubic metres. The ITER Tokamak will be the largest ever built, with a plasma volume of 830 cubic metres.

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 India a part of ITER?

As signatories to the ITER Agreement, the ITER Members China, the European Union, India, Japan, Korea, Russia and the United States will share in the cost of project construction, operation and decommissioning, and also share in the experimental results and any intellectual property generated by the project.

When did India join ITER?

India which formally joined the ITER project in 2005, is responsible for delivery of cryostat, in-wall shielding, cooling water system, cryogenic system, heating systems, Diagnostic Neutral Beam System, power supplies and some diagnostics.

What is the most advanced fusion reactor?

The JET tokamak is the largest and most advanced magnetic fusion reactor currently operating. But the next generation of reactors is already in the works, most notably the ITER experiment, set to begin operations in 2027.

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.

How hot will ITER get?

The temperatures inside the ITER Tokamak must reach 150 million degrees Celsius—or ten times the temperature at the core of the Sun—in order for the gas in the vacuum chamber to reach the plasma state and for the fusion reaction to occur.

Is ITER safe?

The ITER Organization's preliminary safety report concluded that under normal operation the radiological impact of the installation on the most exposed populations would be insignificant since it would be about one-thousandth of the background level of radiation from natural sources.

Will the tokamak work?

Tokamaks are not currently in use for energy production, as scientists still have to overcome the threshold of being able to create more energy than is used to start and maintain the fusion process. It is hoped that the ITER tokamak, which is being constructed in France, will be able to achieve this.

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.

What happens if tokamak fails?

If any of the systems fail (such as the confining toroidal magnetic field) or if, by accident, too much fuel is put into the plasma, the plasma will naturally terminate (what we call “disrupt”) – losing its energy very quickly and extinguishing before any sustained damage is done to the structure.

Can I invest in nuclear fusion?

The process generates energy by fusing or merging atoms. In contrast, nuclear fission, which powers today's nuclear power plants, makes energy by splitting atoms. Nuclear fission technology is already commercialized, and you can invest in it.

Is the UK still part of ITER?

The UK will remain a member of Fusion for Energy. UK companies can continue to bid for ITER contracts tendered by both Fusion for Energy and the ITER organisation. UK researchers and staff can continue working at ITER from 1 January 2021.

Is Pakistan a member of ITER?

Talking to The Express Tribune a senior official of the National Centre for Physics (NCP), who wished not to be named, said that Pakistan has been trying to become an ITER member since 2003, but is still unable to secure a place in the group mainly because of shortage of funds and insufficient number of researchers in ...

When did China join ITER?

Since it joined the Iter project in 2003, China has actively participated in the Iter test blanket programme. It proposed and developed the concept of HCCB TBS.
