Russia’s state atomic corporation Rosatom said on May 24 its TVEL Fuel Company has completed development of the new modification of VVER-440 fuel for Loviisa NPP in Finland. According to Rosatom, the new modification of VVER-440 fuel bundle with higher uranium load would enhance the efficiency of fuel usage and power plant’s operation in general.


In particular, increasing the mass of uranium in one fuel rod would enable to lower uranium enrichment level without reduction of thermal power generation in the reactor. In turn, a lower uranium enrichment will reduce the cost of the nuclear fuel production chain, as well as facilitate handling irradiated fuel.
