A corporate agreement between Rosatom and Rolls-Royce signed during a visit to Moscow by the UK’s prime minister could open up Russia-UK collaboration in nuclear energy.

The firms will consider possibilities for “mutually beneficial co-operation in a comprehensive series of activities in Russia, the UK and third countries,” said Rosatom’s deputy head Kirill Komarov.

Collaborative work between the two firms under the memorandum of understanding could total £1bn (£1.6bn) in value, according to the office of UK Prime Minister David Cameron.

Cameron met his Russian counterpart Dmitry Medvedev in an attempt to improve relationships between the two countries, which have been tense since the murder of the Russian émigré Alexander Litvinenko in London in 2006.

“We have agreed to work together on a range of issues, including the development of nuclear energy, and I’m delighted that this means Rolls-Royce will be working with Rosatom,” said Cameron.

The Russian state nuclear giant Rosatom is currently building ten large power stations at home and three abroad. Rolls-Royce provides instrumentation and controls for systems in France’s 58 nuclear power reactors and for another 50 around the world.
