The
70ies and the first half of the 80ies are characterized by the most intensive
nuclear industry development in Russia. In 1970 the development of serial
pressurized water reactor with electrical capacity of 1000 MW - VVER-1000
reactor began.
In 1980 the first commercial variant of new reactor was
put into operation at Novovoronezh NPP. At the next stage of nuclear industry
evolution (till 1995) 20 reactor units with VVER-1000 reactors were built
and put into operation on the European territory
of Russia, in the Ukraine and Bulgaria.
Since
the 90ies the construction of VVER-1000 reactor units with increased safety
began in Central and South-Eastern Asia. At the
beginning of twenty first century 438 nuclear power reactors with total
installed power nearly 350 Mln. kW producing 16% of the total electrical
energy output in the world were in operation at NPPs the world over. Approximately
6% of nuclear power reactors in the world operate using nuclear fuel produced
at JSC NCCP.
Fuel
assembly (FA) production cycle includes the following operations: uranium
dioxide powder fabrication and the fuel pellets on its basis, fuel pellets
filling into the cladding, fuel element pressurization, fabrication of
component parts and FA assembly. This production cycle is in operation
and is constantly improved during more than 20 years. Production processes
are based on the latest achievements in the field of treatment and welding
of zirconium alloys, material protection from local and general corrosion,
heat transfer, stabilization of the applied material structure and their
physical and mechanical characteristics
Fuel element (FE) and fuel assembly (FA) production complex is provided
with automated equipment, modern control systems thanks to which the production
process stability and high product quality is guaranteed.
Constant improvement of FA - the principal component
of nuclear reactor cores provides for evolution of consumer fuel characteristics,
high level of fuel operation safety and reliability.
Nuclear fuel users confidence
in high quality of supplied products is based on the stable quality assurance
system developed in accordance with the requirements of international
standard ISO 9002 and certified by RF Gosstandart.
