BN reactor fuel
In the 1970’s JSC Mashinostroitelny Zavod commenced serial production of BN-350 and BN-600 nuclear fuel. BN-600 fuel is characterized by increased enrichment by uranium-235 as compared with VVER. Due to liquid sodium coolant used in BN reactor corrosion resistance steel is used as a structural material for fuel rods and assemblies.

Nuclear power industry is one of the youngest and most dynamically developing branches of the world economy. Its development is encouraged by the growing demands of the mankind for fuel and energy in view of limited renewable resources.
It should be noted that spent or irradiated nuclear fuel after special reprocessing can be used again.

Nuclear fuel cycle
Nuclear fuel cycle is a combination of techniques for mining uranium, nuclear reactor fuel production and preparing the fuel for the use and after-use disposal. The notion “fuel cycle” specifies the fact that spent or irradiated nuclear fuel (SNF) can be regenerated after special treatment. The nuclear fuel cycle, including ultimate disposal of high-level waste, takes generally 50 to 100 years.
Nuclear power fuel cycle can be divided into three phases. The initial phase covers uranium ore mining through supply of fabricated fuel assemblies to NPP sites. The next phase includes reactor operation to generate electricity and temporary store SNF at NPP site. The final phase includes several operations: irradiated fuel transportation to a special storage facility or SNF reprocessing plant and burial of vitrified high-level waste after reprocessing.
