Composites are in demand in the nuclear industry

On the eve of the New Year in the company of the state corporation "Rosatom" in Snezhinsk — Russian Federal Nuclear Center — All-Russian Research Institute of Technical Physics (VNIITF) completed repairs of composite materials based on carbon fiber — The reinforcement system of carbon ribbons FibARM.

Just last year the composites was renovated six nuclear facilities.

The object of repair Snezhinsk — crane beams of one of the industrial buildings. As the sales manager of the Holding Company "Composite" Eugene Rafailov, "In recent years, due to the non-project bearing crane rail, beams perceived increased loads, resulting in cracks in them, and a decrease in the strength of concrete, and as a consequence — the loss of bearing capacity."

According to Eugene Rafailova, the use of external reinforcement systems carbon ribbons FibARM to repair beams was found to be optimal. The technology developed by the Holding company "Composite" managing the assets of "Rosatom" for the production of carbon fiber.

Repair lasted a month with a small non-stop production. Carrying out repairs using traditional materials of concrete and metal would have taken much longer and would require virtually complete stop production. The loss of the bearing capacity of the crane structure was rebuilt according to the requirements of the enterprise at 35% of the project status.

In late December, repairs were completed with the use of carbon fiber for another two plants of the state corporation "Rosatom". At the Federal State Unitary Enterprise "Instrument-Making Plant" in Trehgornyi conducted gain slabs and beams in one of the buildings. And of "Chepetsky Mechanical Plant" in Glazov carbon ribbons were reinforced plate and cover in one of the buildings of an industrial building.

The reinforcement system earlier carbon ribbons FibARM was used for the repair of industrial buildings at FSUE "PA" Mayak ", Ozersk. There intensely concrete pipe height of 40 meters with the use of carbon rods and a carbon-reinforced shotcrete. Composites are also used to repair facilities at FSUE FNPC "" Start "in Zarechnyj and the Kovrov Mechanical Plant, which is part of" fuel elements ".

The project is implemented within the framework of the "Program implementation polymer composite materials at nuclear industry", approved by the Director General of the State Corporation "Rosatom" Sergey Kiriyenko in July 2011.
