Scientists now began to assemble a giant machine in southern France after they got an official go-ahead after 14 years of waiting.




The machine which is designed to demonstrate that nuclear fusion same as on Sun, that power the sun and other stars emit can be safely produced and viable energy source too and that too on earth.

ITER is the multinational experiments has been receiving the components in the tiny commune of saint-paul-les-Durance from worldwide in the recent months amid the pandemic.


the project ITER has been considered as the worlds largest puzzle. scientists believe that the assembling must be painstakingly done.

with initial experiments set to begin in December 20205, the plant's goal, for now, is to demonstrate that that fusion power can be generated sustainably, safely, that too on a large commercial scale.

the fusion power the all the stars including our sun produced when light and atomic nuclei fuse together to form heavier-ones releases a huge amount of energy in doing so.

the big challenge for those scientists is to build a machine that can harness the energy released which is meant to be held in the reactor vessel and controlled by an immensely strong magnetic field.

"With fusion, nuclear holds promise for the future, As a technology, it promises clean, no-carbon, safe and practically waste-free energy," - French President Emmanuel Macron said in a message broadcast to an event Tuesday to mark the official start of assembly.

South Korea's President Moon Jae-in, for his part, hailed "the biggest international science project in human history," which he said offered hope of a clean, safe energy source as soon as 2050.

ITER project was landed in 2006 by 38 countries including united states, Russia, China, Britain, India, Japan, South Korea and also 28 members of the europian union(EU).

"Fusion is safe, with minute amounts of fuel and no physical possibility of a run-away accident with meltdown" as with traditional nuclear power stations, the partners said in a statement.

"A pineapple-sized amount of this fuel is the equivalent of 10,000 tonnes of coal," the partners said.

A further advantage: the fuel for fusion and lithium to help manage the reaction is found in seawater and is abundant enough to supply humanity for millions of years

Its "Tokamak" nuclear fusion reactor will comprise about a million components in all, some like its hugely powerful superconducting magnets standing as high as a four-floor building and weighing 360 tonnes each.

Some 2,300 people are at work on-site to put the massive machine together.

"Constructing the machine piece by piece will be like assembling a three-dimensional puzzle on an intricate timeline," said ITER's director-general Bernard Bigot.

"Every aspect of project management, systems engineering, risk management and logistics of the machine assembly must perform together with the precision of a Swiss watch," he said, adding: "We have a complicated script to follow over the next few years."

Once finished, the reactor should be able to recreate the fusion processes that occur at the heart of stars at a temperature of some 150 million degrees Celsius, 10 times hotter than the sun.

It could reach full power by 2035, but as an experimental project, it is not designed to produce electricity.

If the technology proves feasible, future fusion reactors would be capable of powering two million homes each at an operational cost compared to those of conventional nuclear reactors.

The ITER project is running five years behind schedule and has seen its initial budget triple to some 20 billion euros ($23.4 billion).
