TVEL, the fuel-manufacturing subsidiary of Rosatom, delivered a batch of fuel for China's Experimental Fast Reactor (CEFR). The CEFR reactor has been operating with Russia-supplied HEU fuel (reported to be 64.4% HEU) since 2010. Additional fuel supply agreements were reached in 2013 (one batch) and in 2016 (two batches). It is not immediately clear if the fuel delivered in July 2019 completes the supply under the 2016 agreement.
