Funding worth £13 million has been awarded to develop innovative technologies for current and next-generation nuclear power stations.
A total of 15 research and development projects as well as 26 smaller-scale feasibility studies will share the fund.
They include remote monitoring and sensors to eliminate the danger of people entering radioactive areas, an ocean imaging system to stop jellyfish blooms blocking cooling water intakes and extending the working lives of existing nuclear power stations.
The competition is a joint initiative between Innovate UK, the Nuclear Decommissioning Authority (NDA) and DECC.
Business Secretary Vince Cable said: “The nuclear industry offers billions of pounds of business opportunities for British businesses so we want to make the most of this growing sector. That is why we are funding inventors to use innovative processes to protect this valuable industry.
“Long-term, we will safeguard Britain’s legacy for ideas and ingenuity through the forthcoming Science and Innovation Strategy.”
