The Corporation’s share at the world market amounts up to 17%. The products are supplied to 13 countries. TVEL-labeled nuclear fuel runs 46 foreign commercial reactors as well as research reactors of many countries.
The Corporation supplies to traditional foreign markets, which operate the Russian (Soviet) design NPPs and to the Western Europe countries. Presently, JSC TVEL supplies and renders scientific and engineered support to nuclear fuel operation at NPPs of Ukraine, the Czech Republic, Bulgaria, Hungary, Slovakia, Lithuania, Finland and Armenia. High-end technological products of the Corporation are in demand in such countries as Germany, the Netherlands, Sweden and Switzerland. The Russian nuclear fuel runs research reactors in Hungary, Kazakhstan, Uzbekistan, Poland, Ukraine, the Czech Republic, Bulgaria, Vietnam and Libya.
The Corporation is continuously expanding sales markets, in particular, through the contracts for fuel supplies to Asia. In 2004 fuel supplies were commenced for CEFR reactor and Tianwan NPP (China).
Expanded geography is a result of nuclear fuel supplies secured for newly commissioned power units. Two new power units - Khmelnitski-2 and Rovno-4 – were commissioned in 2004 in Ukraine and use the Russian fuel. Once new power units are constructed and commissioned in India (Koodankulam NPP) and Iran (Busherh NPP) it is planned to supply nuclear fuel as well.

Questions & Answers
Nuclear fuel means fuel assemblies (FAs). FA is a complex construction, the main element of which being a bundle of fuel rods made from stainless steel or zirconium. A bundle of fuel rods is filled with uranium dioxide pellets, enriched to 5 % U235. Rods, sealed tightly and loaded with fuel pellets, are called "fuel rods". In order to reduce the gaps between fuel rods and to acquire the necessary structural rigidity, fuel assembly has a number of structural elements: tailpiece, cap and a set of spacing grids. In some cases, they are equipped with a shroud tube. Depending on the reactor types FAs have different number of rods.
Nuclear fuel is delivered by air, sea, railway and motor special transport. Previously, it is placed in high-strength metallic containers, specially certified for transportation of nuclear materials. A special route and transportation schedule are worked out; an additional control of safe transportation on the way is provided. Fuel transportation has never experienced a single accident resulted in enhancement of radiation background.
