ROSATOM Modification for Lower Uranium Enrichment for Loviisa NPP
Rosatom’s TVEL Fuel Company of has completed development of the new modification of VVER-440 fuel for Loviisa NPP in Finland. 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.
The project of developing and validating the new fuel has been accomplished with contribution from a number of Russian nuclear industry enterprises, such as OKB Gidropress (an enterprise of ROSATOM machine-building division Atomenergomash), Bochvar Institute (material science research facility of TVEL Fuel Company), Elemash Machine-building plant and Kurchatov Institute national research center. The new fuel passed a range of hydraulic, longevity and vibration tests at the OKB Gidropress research and experiment facility site
TVEL Fuel Company of Rosatom (Fuel Division of the Rosatom State Corporation) includes enterprises for fabrication of nuclear fuel; conversion and enrichment of uranium, production of gas centrifuges. It also includes the research and development organizations. TVEL is the only supplier of nuclear fuel for Russian nuclear power plants; moreover, it supplies, in total, the fuel for 75 power reactors in 15 countries, and for the research reactors in 9 countries of the world, as well as for the fleet reactors of the Russian nuclear fleet. Every sixth power reactor in the world runs on TVEL fuel.
