These results enable the operation to be estimated for a particular reactor and allow access to details that could not have been gained through measurements alone.
A detailed analysis of results enables engineers to improve reactor design for higher energy efficiency. Such reactors not only improve operating conditions
but also allow for a more sustainable use of resources. These outstanding results were possible thanks to a partnership between Prof.

The reactor itself would be largely self-sustaining meaning it would continuously heat the plasma to maintain thermonuclear conditions.
Heat generated from the reactor would heat up a coolant that is used to spin a turbine
and generate electricity similar to how a typical power reactor works. his is a much more elegant solution because the medium in

An unexpected pattern has been glimpsed in the solar wind the turbulent plasma of charged particles that streams from the sun. It offers clues for handling plasmas that roil inside nuclear fusion reactors On earth.
The result may help to control nuclear fusion reactors. These create energy in the same way as the sun by fusing a superheated plasma of hydrogen nuclei to form helium.
which can cause plasma to escape the magnetic field containing it in the reactor. They may also be able to use turbulence to disrupt high energy plasma blobs that can rip holes in the reactor.
These results look very promising says Todd Evans of nuclear energy firm General Atomics in San diego California.

The UK government has been criticised for guaranteeing the price that will be paid for any electricity the new Hinkley Point reactor produces.
or £89. 50 if EDF develops another new reactor in Sizewell, Suffolk. This simply reflects the fact that EDF's costs will be lower per reactor
if it builds two of them. If the market price of electricity falls below this level, the government has said in effect it will make sure EDF receives the difference between the two prices.
For this reason, EDF needs an added incentive to build the reactors. Knowing it will receive a guaranteed price for the electricity generated at Hinkley provides some kind of certainty that the investment will be worthwhile-in other words, profitable.
paving the way for other power companies to invest in new reactors in the UK, because two new reactors will not be enough
