On 14 February, this report from RUSI says that Russia’s nuclear energy exports continue to expand, even as its overall economy bears the brunt of Western sanctions. Rosatom State Nuclear Energy Corporation (Rosatom), which has a monopoly over the Russian nuclear industry, has continued exports of nuclear fuel and other goods relevant to the nuclear energy sector. According to Russian customs data, sourced through a third-party commercial trade data provider, Russia has exported just over $1 billion-worth of nuclear energy-related goods and materials since the start of the war in Ukraine. It notes that generous Russian financing arrangements make Russia an attractive supplier among its other competitors in the nuclear energy sector.
