Tubes
The plant’s pipe-rolling workshop manufactures complete spectrum of tubes required for nuclear fuel production. The applied technology and equipment enable the Works to manufacture high-precision tubes of geometrical size ± 0,03 mm, and with such surface quality that defect level not exceeds 0,015 mm at depth and with the minimal range of parameters according to microstructure and mechanical properties.

RBMK-1000 fuel assemblies have been serially manufactured since 1973 but RBMK-1500 fuel assemblies were commenced in 1982. The supplies are made to Russia (Leningrad NPP, Kursk NPP, Smolensk NPP) and Lithuania (Ignalina NPP).
The RBMK-1000 and RBMK-1500 fuel assemblies with burnable poison are made of zirconium alloys. Their life is up to 8 years to ensure nuclear safety and good economics. RBMK-1000 fuel assemblies widely use the recovered nuclear fuel.

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.
