The first production batch of low-enriched fuel assemblies (19.7%) "MR" for the Polish research reactor "Maria" is manufactured at the Novosibirsk Chemical Concentrates Plant (part of Rosatom Fuel Company "TVEL"). FAs are accepted by representatives of the National Centre for Nuclear Research (NCBJ, Otwock, Poland) on the territory of PJSC "NCCP".
Until recently, the "Maria" reactor has used French low-enriched fuel. Developed by Russian specialists LEU fuel assembly has higher consumer properties in comparison with the French, which allowed the Russian side to win the tender in 2015 and to sign the contract for the supply of fuel assemblies "MR" in Poland.
As a result of acceptance, the bilateral protocol was signed, which says FAs meet requirements of the contract and are ready for delivery to Poland.
