About In a few lines. What is ITER? What will ITER do? What is Fusion? What is a Tokamak? Who is participating in ITER? When will experiments begin? See images. The experimental campaign that will be carried out at ITER is crucial to advancing fusion science and preparing the way for the fusion power plants of tomorrow.
ITER will be the first fusion device to produce net energy. ITER will be the first fusion device to maintain fusion for long periods of time. And ITER will be the first fusion device to test the integrated technologies, materials, and physics regimes necessary for the commercial production of fusion-based electricity. Thousands of engineers and scientists have contributed to the design of ITER since the idea for an international joint experiment in fusion was first launched in Until a new arrangement is reached, the ITER Council has agreed that existing contracts, both with personnel and suppliers, will be honoured.
Fusion is the energy source of the Sun and stars. In the tremendous heat and gravity at the core of these stellar bodies, hydrogen nuclei collide, fuse into heavier helium atoms and release tremendous amounts of energy in the process.
Twentieth-century fusion science identified the most efficient fusion reaction in the laboratory setting to be the reaction between two hydrogen isotopes, deuterium D and tritium T. The DT fusion reaction produces the highest energy gain at the "lowest" temperatures. At extreme temperatures, electrons are separated from nuclei and a gas becomes a plasma—often referred to as the fourth state of matter.
Fusion plasmas provide the environment in which light elements can fuse and yield energy.

India, which has already spent close to Rs 2, crore on this project that involves building a megawatt fusion reactor, is supplying nine different packages, including cryostat, cooling water systems, vessel in-wall shielding blocks, radio frequency heating sources, cryodistribution and cryolines, power supplies, diagnostic neutral beam system and some of the diagnostics systems. The aim of the ITER project, which began inis to determine whether nuclear fusion can be a source of energy and electricity in the future.
The European Union accounts for 69 percent of the members working for the ITER and contributes 45 percent of the construction cost. However, ITER officials said the project, which is expected to get commissioned by Decemberwill not suffer despite Britan deciding to leave the European Union.

It has been designed as a medium-sized tokamak with superconducting magnets. The SST-1 project will increase India's stronghold in a selected group of countries who are capable of conceptualizing and making a fully functional fusion based reactor device. Saxena, Dr. Chenna Reddy, and is headed by Dr.
Subrata Pradhan. The first talks about SST Mission started in The technical details and mechanical drawings of the system were finalized in The machine was fabricated by Godrej -Boyce Pvt.
The improved version of the machine was completely assembled by January It was fully commissioned in As of Dec it is having upgrades including to the plasma facing components to allow longer pulses. This is a pretty good scheme in which creation, current-drive and heating are neatly integrated and remained a choice of the fusion community for many years until the stage came to heat the plasma to multi-keV temperatures. However, for relevance to future power reactors it is essential to operate these devices in a steady state mode.
The very idea of steady state operation presents a series of physics and technology challenges. For example, the excellent plasma performance which was accomplished earlier, was with the surrounding material wall acting as a good 'pump' of particles, a fact which may not be true in steady state.
Secondly, a host of engineering and technical considerations spring up. The magnets must be superconducting type, otherwise the power dissipation in conventional resistive types can reach uneconomical levels. The heat and particle exhaust must be handled in steady state with specialized tiles and active cooling. The advanced, so-called double null divertor plasma configuration has to be maintained through efficient feedback control avoiding plasma disruptions over long discharge durations.
SST-1 will feature many new plasma diagnostic devices, many of which are being used for the first time in fusion research in India. Some of the novel plasma diagnostics devices incorporated in SST-1 are:. Almost all of the diagnostic devices installed on SST-1 are indigenous and are designed and developed by Diagnostics Group of Institute for Plasma Research.Our simple visualization tracks the spread of Coronavirus by each day, and by each state in India.

The ITER thermonuclear fusion reactor has been designed to produce a fusion plasma equivalent to megawatts MW of thermal output power for around twenty minutes while 50 megawatts of thermal power are injected into the tokamak, resulting in a ten-fold gain of plasma heating power.
The total electricity consumed by the reactor and facilities will range from MW up to MW peak for second periods during plasma operation.
The emitted heat from the fusion reaction will be vented to the atmosphere. The EU, as host party for the ITER complex, is contributing about 45 percent of the cost, with the other six parties contributing approximately 9 percent each. Initial plasma experiments are scheduled to begin inwith full deuterium — tritium fusion experiments starting in The goal of ITER is to demonstrate the scientific and technological feasibility of fusion energy for peaceful use.
DEMO's anticipated success is expected to lead to full-scale electricity-producing fusion power stations and future commercial reactors. Fusion power has the potential to provide sufficient energy to satisfy mounting demand, and to do so sustainably, with a relatively small impact on the environment. Nuclear fusion has many potential attractions. Firstly, its hydrogen isotope fuels are relatively abundant — one of the necessary isotopes, deuteriumcan be extracted from seawaterwhile the other fuel, tritiumwould be bred from a lithium blanket using neutrons produced in the fusion reaction itself.
On 21 Novemberthe seven participants formally agreed to fund the creation of a nuclear fusion reactor. When supplied with MW of electrical power, ITER is expected to produce the equivalent of MW of thermal power sustained for up to 1, seconds.
The heat produced in ITER will not be used to generate any electricity because after accounting for losses and the MW minimum power input, the output will be equivalent to a zero net power reactor. Preparations for the first Gorbachev-Reagan Summit showed that there were no tangible agreements in the works for the summit. One energy research project, however, was being considered quietly by two physicists, Alvin Trivelpiece and Evgeny Velikhov.
The project involved collaboration on the next phase of magnetic fusion research — the construction of a demonstration model. Velikhov and Trivelpiece believed that taking the next step in fusion research would be beyond the budget of any of the key nations and that collaboration would be useful internationally.
A major bureaucratic fight erupted in the US government over the project. One argument against collaboration was that the Soviets would use it to steal US technology and know-how. A second was symbolic — the Soviet physicist Andrei Sakharov was in internal exile and the US was pushing the Soviet Union on its human rights record. Martin and Velikhov concluded the agreement that was agreed at the summit and announced in the last paragraph of this historic summit meeting, " The two leaders emphasized the potential importance of the work aimed at utilizing controlled thermonuclear fusion for peaceful purposes and, in this connection, advocated the widest practicable development of international cooperation in obtaining this source of energy, which is essentially inexhaustible, for the benefit for all mankind.
On 21 Novemberan international consortium signed a formal agreement to build the reactor. ITER's mission is to demonstrate the feasibility of fusion power, and prove that it can work without negative impact.
The ITER project was initiated in When deuterium and tritium fuse, two nuclei come together to form a helium nucleus an alpha particleand a high-energy neutron. While nearly all stable isotopes lighter on the periodic table than iron and nickelwhich have the highest binding energy per nucleonwill fuse with some other isotope and release energy, deuterium and tritium are by far the most attractive for energy generation as they require the lowest activation energy thus lowest temperature to do so, while producing among the most energy per unit weight.
All proto- and mid-life stars radiate enormous amounts of energy generated by fusion processes. Mass for mass, the deuterium—tritium fusion process releases roughly three times as much energy as uranium fission, and millions of times more energy than a chemical reaction such as the burning of coal.
It is the goal of a fusion power station to harness this energy to produce electricity. Activation energies for fusion reactions are generally high because the protons in each nucleus will tend to strongly repel one another, as they each have the same positive charge.
In ITER, this distance of approach is made possible by high temperatures and magnetic confinement. High temperatures give the nuclei enough energy to overcome their electrostatic repulsion see Maxwell—Boltzmann distribution. For deuterium and tritium, the optimal reaction rates occur at temperatures on the order ofK. The plasma is heated to a high temperature by ohmic heating running a current through the plasma.
Additional heating is applied using neutral beam injection which cross magnetic field lines without a net deflection and will not cause a large electromagnetic disruption and radio frequency RF or microwave heating.
