Rosatom’s Mechanical Engineering Division has completed the manufacturing of key equipment for Russia’s Generation IV nuclear power unit, currently under construction as part of the Pilot Demonstration Energy Complex (PDEC).
The 300 MW power unit is based on the innovative BREST-OD-300 fast neutron reactor, which uses lead as a coolant—a significant advancement in next-generation nuclear technology.
Six critical components, weighing over 1,000 tons in total, have already been produced. Unlike the VVER and RITM reactor units, which Rosatom has mass-produced for years, the BREST-OD-300 features uniquely shaped and dimensioned elements to accommodate its cutting-edge design.
Designed to operate at temperatures up to 600 degrees Celsius, the reactor requires specialized steel with exceptional mechanical strength. The reactor unit will be assembled directly at the construction site, where approximately 2,300 tons of equipment will be delivered. Once completed, the full installation, including concrete structures, will weigh around 16,000 tons.
This project marks a major step toward the realization of Generation IV nuclear energy systems, which aim to offer enhanced safety, sustainability, and fuel efficiency.
