Will ITER break even?
Assuming the same ηheat = 0.7 and ηelec = 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 energy positive?
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.
How does the ITER work?
In the core of the sun, huge gravitational pressure allows fusion to take place at temperatures of around 15 million °C. To achieve fusion, therefore, ITER will use a device called a tokamak, which holds the reacting plasma away from the furnace’s walls with intense magnetic fields.
How much energy does ITER produce?
ITER will produce about 500 MW of fusion power in nominal operation, for pulses of 400 seconds and longer. Typical plasma heating levels duriung the pulse are expected to be about 50 MW, so power amplification (Q) is 10. Thus during the pulse the ITER plasma will create more energy than it consumes.
Is ITER completed?
The ITER project was initiated in 1988. Ground was broken in 2007 and construction of the ITER tokamak complex started in 2013. Machine assembly was launched on 28 July 2020….Timeline and status.

How is ITER doing?
As of May 2021 ITER is near 75\% complete toward first plasma. Start is scheduled for late 2025. The start of the project can be traced back to 1978 when the European Commission, Japan, United States, and USSR joined together for the International Tokamak Reactor (INTOR) Workshop.
What is the role of ITER in modern energy sources?
ITERs goals are: to achieve enough fusion to produce 10 times as much thermal output power as thermal power absorbed by the plasma for short time periods; to demonstrate and test technologies that would be needed to operate a fusion power plant including cryogenics, heating, control, and diagnostics systems, including …
What is Lawson criterion in nuclear fusion?
Lawson criterion of important magnetic confinement fusion experiments The Lawson criterion is a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment.
What is the Lawson criterion for energy balance?
Energy balance. The central concept of the Lawson criterion is an examination of the energy balance for any fusion power plant using a hot plasma. This is shown below: Net power = Efficiency × (Fusion − Radiation loss − Conduction loss) Net power is the excess power beyond that needed internally for the process to proceed in any fusion power plant.
What is the closest we can get to Lawson’s criterion?
The closest approach to Lawson’s criterion has been at the Tokamak Fusion Test Reactor (TFTR) at Princeton. It has reached ignition temperature and gotten very close to Lawson’s criterion, although not at the same time.
What are the conditions for fusion to occur?
Conditions for Fusion. In addition to providing a sufficiently high temperature to enable the particles to overcome the Coulomb barrier, that temperature must be maintained for a sufficient confinement time and with a sufficient ion density in order to obtain a net yield of energy from a fusion reaction.
