The agreement follows a similar memorandum signed by the nuclear agency and another Russian aluminum giant, Rusal, earlier in the day.
The memo signed with SUAL focuses on joint long-term investment projects.
Under the document, SUAL and the agency-controlled Research Institute for Nuclear Power Plant Operation (VNIIAES) will set up a headquarters for talks on implementing joint projects, determining construction sites, developing mechanisms for cooperation and setting the terms of project contracts.
One of the world's top 10 aluminum companies, SUAL has enterprises in nine Russian regions and in Ukraine, and annually mines over 5.4 million metric tons of bauxite, some 2.3 mln metric tons of alumina, over 1 mln tons of primary aluminum, and about 60,000 metric tons of silicon. It also manufactures aluminum products, including foil, wire, and wheel rims, and exports 80% of its production.
