But Rosatom is not just a supplier of civil nuclear infrastructure. The company is one of the key stewards of Russia’s nuclear weapons complex and is increasingly involved in developing and supplying conventional weapons to the Russian military, including systems being deployed in Ukraine. Yet Russia’s nuclear sector remains largely unsanctioned, allowing Rosatom to continue generating revenue, including from business in Europe. According to the Stokholm International Peace Research Institute, as of 2016, enterprises in Rosatom’s nuclear weapons complex employed about 38% out of the company’s 250,000 employees. These Rosatom subsidiaries conduct nuclear weapons research, assembly and related material production, and several have come under US and/or EU sanctions.
