The final, seventh block truss for covering the turbine hall roof for Rosatom’s Brest-OD-300 reactor plant has been installed in the design position.
The Brest-OD-300 lead-cooled fast reactor is being built at the Siberian Chemical Combine (SKhK – Sibirskovo Khimicheskovo Kombinata) in Seversk, Tomsk region. Brest (Bistrii Reaktor Estestvennoi-bezopasnosti co Svinstovim Teplonositelem – Fast Natural-safety Reactor with Lead Coolant) is part of the pilot demonstration power complex (ODEK – Opitno Demonstratsionovo Energo-Kompleksa), being built under the Breakthrough (Proryv) project intended to demonstrate closed fuel cycle technology. As well as Brest, ODEK also includes on-site nuclear fuel cycle facilities: a module for fabrication and refabrication (MFR-YaT – Modulya po Fabrikatsii/Refabrikatsii Yadernovo Tolpliva) and a module for reprocessing and recycling irradiated fuel.
The metal truss, without equipment, weighs 52 tonnes with a length of more than 42 metres. It was moved to the top point of the turbine hall using a self-propelled Liebherr crane and mounted in the opening between the previously installed structures. Installation was completed within 2.5 hours.
Since May, the builders have installed six block trusses. The total weight of all seven coating blocks, together with the necessary connections and corrugated sheeting, is more than 500 tonnes.
“The completion of roofing work and the creation of a thermal circuit for the turbine room will allow us to continue installing the turbine compartment equipment and begin installing the turbine unit of the power unit in the winter,” noted Ivan Babich, Director of the Brest-OD-300 power unit at ODEK.
During the summer, a large batch of the main power equipment for the power unit was delivered to Seversk. After decades of development, in 2021, regulator Rostechnadzor issued a licence for the construction of the Brest-OD-300 reactor.
