A crucial operation to install metal shells of the peripheral cavity has begun at the site of the innovative power unit with the BREST-OD-300 reactor in Seversk (Tomsk Region). Four large-sized structures, each comparable in size to a five-story residential building, were delivered from the enterprises of Rosatom's machine-building division.
The total weight of the installed elements exceeds 1000 tons. The installation is carried out with millimeter precision using a Liebherr construction crane with a lifting capacity of over 1000 tons — a key piece of equipment for assembling new generation nuclear facilities.
BREST-OD-300 is a power unit with a fast neutron reactor operating on uranium-plutonium nitride fuel and cooled by lead. This is the world's first reactor project implementing the concept of a "closed nuclear fuel cycle" directly at the power unit site: spent fuel will be regenerated and returned to the reactor without being taken outside the facility.
The installation's capacity is 300 MW. The project is being implemented as part of Rosatom State Corporation's "Proryv" strategy and is designed to lay the foundations for safe, cost-effective, and resource-saving nuclear energy of the future.
