Fusion reactors could become an economically viable means of generating electricity within a few decades, and policy makers should start planning to build them as a replacement for conventional nuclear power stations, according to new research.

Researchers at Durham University and Culham Centre for Fusion Energy in Oxfordshire, have re-examined the economics of fusion, taking account of recent advances in superconductor technology for the first time. Their analysis of building, running and decommissioning a fusion power station shows the financial feasibility of fusion energy in comparison to traditional fission nuclear power.

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.
