Brest-OD-300 (nuclear reactor)

2021: Start of nuclear reactor construction

On June 8, 2021, Rosatom announced the start of construction of a 300 MW nuclear power unit with an innovative fast neutron reactor with a lead coolant in Seversk, Tomsk Region. A reactor called Brest-OD-300 will be created at the site of the Siberian Chemical Plant.

The implementation of the project is reported in the official Twitter account of Rosatom. As   the scientific director of the Rosatom enterprise "Research and Design Institute of Power Engineering named after Dollezhal" (NIKIET) Yevgeny Adamov told TASS, the cost of building the reactor is about 100 billion rubles.

Near Tomsk began the construction of an atomic reactor for 100 billion rubles

Initially, Rosatom planned to spend 43-45 billion rubles on the project and implement it until 2021, but as a result, the cost of construction increased, and the deadlines for the start of work shifted.

The facility under construction is an experimental, the world's first model for the development of fourth-generation nuclear technologies, the administration of the Tomsk region reports. Construction is planned to be completed in 2026, the commissioning of the pilot demonstration energy complex is planned for the 2029th.

It is noted that Brest-OD-300 will become a key element of the experimental demonstration energy complex, which also includes a module for fabrication/refabrication of mixed nitride uranium-plutonium nuclear fuel, as well as a module for processing irradiated fuel.

The power unit is being built as part of the Breakthrough project to create a new technological platform for the nuclear industry with a closed nuclear fuel cycle, as well as to solve the problems of spent nuclear fuel.

Fast neutron reactors are more efficient and safer than thermal neutron reactors, by June 2021 in the Russian Federation they are used only at two nuclear power plants.^[1]
