Russia’s state nuclear corporation Rosatom has filed a lawsuit in Moscow against Finland’s Fortum and Outokumpu, demanding 227.8 billion roubles ($2.8bn, €2.4bn) in compensation for losses over the termination of a contract for the Hanhikivi-1 nuclear power plant in Finland, court documents and a Rosatom statement show.

Rosatom is seeking compensation for losses caused “by the unlawful termination of the EPC [engineering, procurement and construction] contract” for the construction of the nuclear power plant, “violations of the shareholder agreement, the fuel supply contract, and the refusal to repay the loan”, the company said on 5 May.
