NCCP. Production of nuclear fuel for nuclear power plants

NCCP. Production of nuclear fuel for nuclear power plants (2012)
Writes Gelio (Stepanov Glory)
It will be 30 pictures, and text.
Novosibirsk Chemical Concentrates Plant - one of the world's leading producers of nuclear fuel for nuclear power plants and research reactors in Russia and abroad. The only Russian manufacturer of lithium metal and its salts. Included in the Fuel Company "TVEL" State Corporation "Rosatom".

Despite the fact that in 2011 the NCCP produced and sold 70% of world consumption of the isotope lithium-7, the main activity of the plant is the production of nuclear fuel for power and research reactors.
This type is dedicated to the current photo essay.

The roof of the main building of the industrial complex

Workshop production of fuel rods and fuel assemblies for research reactors

Plot manufacture uranium dioxide powder by high pyrohydrolysis

Loading of containers with uranium hexafluoride

Room operators
From here there is control of the process of production of uranium dioxide powder, which is then manufactured fuel pellets.

The site manufacturing of uranium pellets
In the foreground are seen bicones, which houses the uranium dioxide powder.
In them the mixing powder and a plasticizer, which allows better compacted tablet.

Tablets nuclear ceramic fuel
They further administration in an oven for annealing.

Torch (post-combustion of hydrogen) in the sintering furnace pellets
Tablets are annealed in an oven at a temperature of not less than 1750 ° in a hydrogen reducing atmosphere for more than 20 hours.

Technical control of nuclear ceramic fuel pellets
One tablet weighing 4, 5 g of energy release is equivalent to 400 kg of coal, 360 cubic meters. m or 350 kg of gas oil.

All work carried out in the pits through special gloves.

Unloading a packing case with pills

Workshop production of fuel rods and fuel assemblies for nuclear power plants

The automated production line TVEL

It is filled zirconium tubes uranium dioxide pellets.
The result is a ready-made fuel rods around 4 m in length - the fuel elements.
Because of the fuel elements already collected FA, in other words, nuclear fuel.

Move finished fuel elements in shipping containers
Shoe even on wheels.

Land assembly TVS
Installing varnish coating on the fuel elements

Securing the fuel rods in the loading mechanism

Making the frame - welding and channel spacing grids
In this framework then install 312 fuel rods.

Technical control framework

Channels and lattice spacing

Automated equipment stands a fuel bundle

Assembling beam

Technical control TVS

Fuel elements with bar-code label on which can be traced back, literally, all the way to the production of the product.

Stands control and packaging of finished fuel assemblies

Control of finished fuel assemblies
Check that the distance between the fuel rods were the same.

Ready TVS

Two-pipe containers for transporting the fuel assembly
Fuel for nuclear power plants produced in the NCCP, used in Russian nuclear power plants and supplied to Ukraine, Bulgaria, China, India and Iran.
I have everything, thank you for your attention
