The US Energy Department has launched a competition to help develop advanced nuclear reactor concepts.
It aims to bring together the nuclear industry with laboratories to help provide clean, affordable and secure energy.
It is looking for proposals for cost-shared advanced reactor development projects, with the potential of being demonstrated by 2035.
The Energy Department will partner with industry to fund up to two awards of around $6 million (£3.9m) each in 2015.
Recipients will be required to invest $1.5 million (£0.96m) as part of the cost share.
Acting Assistant Secretary for Nuclear Energy, John Kotek, said: “We believe this funding opportunity will foster scientific innovation to advance the goals of the Department in developing clean energy technologies.”
