Nuclear fusion financially viable in decades claim researchers

Fusion reactors could become an economically viable means of generating electricity within a few decades, a team of UK researchers has claimed.

The group, from Durham University and Culham Centre for Fusion Energy in Oxfordshire, has re-examined the economics of fusion, and taken into account recent advances in superconductor technology.

The research, published in the journal Fusion Engineering and Design, builds on earlier findings that a fusion power plant could generate electricity at a similar price to a fission plant and identifies new advantages in using the new superconductor technology.

Fusion reactors generate electricity by heating plasma to around 100 million degrees centigrade so that hydrogen atoms fuse together, releasing energy. This differs from fission reactors which work by splitting atoms at much lower temperatures.

The report, which was commissioned by Research Council UK’s Energy Programme focuses on recent advances in high temperature superconductors. These materials could be used to construct the powerful magnets that keep the hot plasma in position inside the containing vessel, known as a tokamak, at the heart of a fusion reactor.
