In Seversk, Tomsk Oblast, concreting of the turbogenerator foundation for the innovative BREST-OD-300 reactor has begun. The work is being carried out by Siberian Chemical Combine, part of Rosatom.
The turbogenerator foundation is designed for seismic loads up to 7 points on a 12-point scale. The structure must ensure the stability of equipment with a total mass of over 1.7 thousand tons and reduce vibrational impact on the power unit's technological systems.
The foundation will be concreted in three stages. The total volume of materials will exceed 620 cubic meters of concrete of various classes – from heavy to fine-grained. The structure will also use more than 100 tons of rebar and embedded parts.
To reduce vibrations, 36 spring elements will be embedded in the foundation. They will reduce the load from the operating turbogenerator on the foundation columns and adjacent equipment.
The BREST-OD-300 project is being implemented as part of the "Proryv" (Breakthrough) industry project, which aims to create a closed nuclear fuel cycle and develop fast neutron reactors. The experimental demonstration power complex in Seversk will combine nuclear fuel production, a power unit with a lead-cooled reactor, and a module for processing irradiated fuel.
