The rotor of the steam turbine and the stator of the generator set for the innovative BREST-OD-300 reactor power unit have been delivered to the construction site of the Generation IV Pilot Demonstration Energy Complex in the city of Seversk, Tomsk Region. The complex is being built at the Siberian Chemical Plant (part of the Fuel Division of the Rosatom State Corporation). The power equipment was transported via the Northern Sea Route and the Tom River, with the final leg completed by special road transport after transshipment at a river port.
The stator weighs 245 tonnes and measures 8 metres in length, approximately 4.5 meters in height, and 4.8 meters in width. The turbine rotor, also delivered by water, weighs 98 tonnes. In addition, the generator rotor was delivered by rail.
“The turbogenerator for the BREST-OD-300 power unit is a unique Russian design featuring full air cooling. Its design ensures enhanced safety and efficiency. For the Tomsk energy system, this will be the most powerful energy facility,” said Ivan Babich, Director of the BREST-OD-300 power unit at the Siberian Chemical Plant.
Rosatom’s
“Proryv” (Breakthrough) project is aimed at achieving a new level of nuclear power development through
the creation and commercial implementation of a closed nuclear fuel cycle based
on fast neutron reactors. The project is managed by JSC “Proryv” and involves
leading Russian scientists and engineers, with participation from a number of
industry institutes. As part of the project, a nuclear energy complex will be
created, comprising a nuclear power plant and facilities for the regeneration
(reprocessing) and refabrication of nuclear fuel. The Pilot
Demonstration Energy Complex is under construction at the site of the Siberian
Chemical Plant (Seversk, Tomsk Region). It will include a power unit with a
BREST-OD-300 reactor using lead coolant, and an on-site plant consisting of a
reprocessing module for irradiated mixed uranium-plutonium (nitride) fuel and a
fabrication/refabrication module to produce initial fuel assemblies from
supplied materials, and later from reprocessed spent nuclear fuel. The complex
is intended to demonstrate the stable operation of systems enabling a closed
nuclear fuel cycle.
In 2021, Rostekhnadzor issued a construction license for the
BREST-OD-300 reactor. According
to IAEA classification, Generation IV nuclear systems involve various
technologies that share common goals: greater fuel efficiency, enhanced safety,
improved energy performance, and reduced nuclear waste. The 300 MW power unit,
based on a fast neutron reactor with lead coolant, is the key facility of the
Generation IV Pilot Demonstration Energy Complex. The complex is being
built at the site of the Siberian Chemical Plant under the strategic industry
project “Proryv.” In addition to the BREST-OD-300 reactor, the energy complex
will also include on-site closed fuel cycle facilities—a plant for the production
of mixed uranium-plutonium nitride fuel and a module for reprocessing
irradiated nuclear fuel.
Rosatom’s Fuel Division managed by TVEL JSC includes enterprises for nuclear fuel fabrication, uranium conversion and enrichment, gas centrifuge manufacturing, and R&D organisations. As the sole supplier of nuclear fuel for Russian NPPs, TVEL provides fuel for over 70 power reactors in 15 countries, research reactors in 9 countries, and propulsion reactors of the Russian nuclear fleet. Every sixth power reactor in the world runs on TVEL fuel. The Fuel Division is the world’s largest producer of enriched uranium and a leader in the global stable isotope market. It is also actively developing new businesses in chemistry, metallurgy, energy storage technologies, 3D printing, digital products, and nuclear decommissioning. The division also hosts Rosatom’s industry integrators for additive technologies and energy storage systems. www.tvel.ru
Siberian Chemical Plant located in Seversk, Tomsk Region unites four nuclear material processing plants: an isotope separation plant, a conversion plant, a radiochemical plant, and a chemical-metallurgical plant. One of the Plant’s main areas of activity is supplying uranium for nuclear fuel to NPPs. The Siberian Chemical Plant is also the site for the “Proryv” project, which aims to create a new technological platform for the nuclear industry based on a closed nuclear fuel cycle using fast neutron reactors. www.shk.tvel.ru
