Russia begins construction of the new generation BREST nuclear reactor


 

Russia proceeded to the construction of the lead-cooled fast neutron reactor BREST-OD-300, the future heart of a pilot complex that will respond to the challenges of safety, sustainability, and competitiveness in the nuclear industry.


The first concreting in what will be the foundations of the new generation reactor was carried out on the premises of SCC (Siberian Chemical Combine), a plant of the Rosatom Corporation located in Séversk, in the Tomsk province (Siberia). A Sputnik correspondent attended the solemn ceremony that was attended by senior officials from the region and the nuclear sector.


The president of the Rosatom Supervisory Council and the first deputy head of Russia's presidential cabinet, Sergei Kirienko, described the start of the works as a radical advance.


Something we have dreamed of has come true, something that we have worked on and been preparing for a long time. Russia becomes the first in the world to achieve a closed nuclear fuel cycle, Kirienko said in a message sent to Séversk on the occasion of the event.


According to the Rosatom corporation, their design is an integral composition, since the steam generators are placed in a multilayer metal and concrete casing within the reactor block.


In turn, the director-general of the International Atomic Energy Agency, Rafael Grossi, declared that the world nuclear industry is advancing thanks to the Russian technology used in the BREST project.


The Russian nuclear power corporation Rosatom and the Russian Federation, as well as the global nuclear industry as a whole, are moving forward with the start of construction of BREST, Grossi said.


The physical launch of BREST, which will have a capacity of 300 MW, is scheduled for 2026.


The use of a lead coolant with a boiling point of the order of 1,700 ° C, dense mononitride fuel with a melting point greater than 2,800 ° C, passive removal of residual heat, and the ability to circulate the coolant even with The turned off pumps are natural safety systems that prevent any serious accident, such as the one that occurred in Chernobyl, in 1986, or in Fukushima, in 2011.


The BREST-OD-300 is part of an experimental pilot complex (ODEC) that will also include a fuel manufacturing-remanufacturing module and a spent nuclear fuel reprocessing module.
