#This fusion reactor could be cheaper than coal University of Washington Posted by Michelle Ma-Washington on October 16 2014fusion energy almost sounds too good to be true#zero greenhouse gas emissions no long-lived radioactive waste a nearly unlimited fuel supply.
They have designed a concept for a fusion reactor that when scaled up to the size of a large electrical power plant would rival costs for a new coal fired plant with similar electrical output.
The team published its reactor design and cost-analysis findings last spring and will present results this week at the International atomic energy agency s Fusion energy Conference in St petersburg Russia. ight now this design has the greatest potential of producing economical fusion power of any current conceptsays Thomas Jarboe a professor
The reactor called the dynomak started as a class project taught by Jarboe two years ago.
After the class ended Jarboe and doctoral student Derek Sutherland#who previously worked on a reactor design at the Massachusetts institute of technology#continued to develop
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
which is crucial to keeping a fusion reactor going. The new design is known as a spheromak meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself.
and actually allows researchers to shrink the overall size of the reactor. Other designs such as the experimental fusion reactor project that s currently being built in France#called Iter#have to be much larger than the dynomak
because they rely on superconducting coils that circle around the outside of the device to provide a similar magnetic field.
When compared with the fusion reactor concept in France the dynomak is much less expensive#roughly one-tenth the cost of Iter
Jarboe and colleagues factored the cost of building a fusion reactor power plant using their design and compared that with building a coal power plant.
because the commercial reactor unit already looks economicalsutherland says. t s very exciting. ight now the concept is about one-tenth the size and power output of a final product

#Self-healing materials could lead to safer nuclear reactors One of the key challenges when designing nuclear reactors is finding materials that can withstand the massive temperatures, radiation, physical stress and corrosive conditions of these extreme environments.
Exposure to high radiation alone produces significant damage at the nanoscale, so scientists at Los alamos National Laboratory, New mexico, have been working on a mechanism that allows nanocrystalline materials to heal themselves after suffering radiation-induced damage.
This gives hope for materials that will improve the reliability, safety and lifespan of nuclear energy systems.
or accelerate the design of highly radiation-tolerant materials for the next generation of nuclear energy applications.

Within India, DAE employees are concerned that an influx of proposed new reactors could lead to quality standards being compromised.
The country's Atomic energy Regulatory Board will have to inspect and clear several new reactors of different designs as they are approved."
"Our primary concern is over safety, "says A. Sathasivam, president of the National Federation of Atomic energy Employees.

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.
Though less dense and cooler than the hydrogen of a fusion reactor the wind is a plasma
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.

David cameron and President Xi Jingping are expected to sign a deal this afternoon agreeing to Chinese investment in a new nuclear power station in Somerset.
The UK government has been criticised for guaranteeing the price that will be paid for any electricity the new Hinkley Point reactor produces.
The government has maintained all along that it will not provide any public subsidies to the nuclear industry. It would not actually be illegal to do so,
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.
Nuclear reactors cost a lot of money, and EDF wants to build two of them. The final bill for just Hinkley is estimated at £24. 5bn.
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.
In other words, how much of your electricity is generated by nuclear power. At the moment, almost 20%of the UK's power is generated by nuclear reactors
but this is likely to fall in the short term as the UK's current nuclear capacity is decommissioned.

he predicted, providing a cheaper alternative to nuclear power 24-hour output. Gundersen predicted the cost of the utility-scale battery would fall to 2 cents per kwh of the electricity that passes through it
which in coming years would render renewable energy with reliable storage cheaper than a new nuclear plant.

Several privately funded companies and small university-based research groups pursuing novel fusion reactor designs have delivered promising results that could shorten the timeline for producing a prototype machine from decades to several years.
