ITER fusion reactor enters key construction phase.

The $20bn fusion reactor has entered it&amp;#8217;s first key phase of construction which involves pouring 15,000 cubic metres of concrete into a hole on the site in the south of France. The plan for ITER was born in 1985 at the Geneva Superpower Summit, the idea was to develop fusion energy for peaceful purposes because it&amp;#8217;s benefits are so great.
Construction first started in 2010, but has since fallen behind schedule, with physicists now wanting to start the first experiments in 2020, but not use any of the hydrogen isotopes until 2027.&nbsp;David Campbell,who is the project&rsquo;s head of plasma operation, said this: &ldquo;Although there are a lot of uncertainties in fusion plasma physics and it will take some time to optimise conditions in the reactor, the work already done [in smaller experiments and computer modelling] makes me confident there are no show-stoppers to prevent us producing a few hundred megawatts of fusion power.&rdquo;
