A Rosatom feasibility study has concluded that up to 38 cogeneration reactors could potentially be deployed at 14 sites for this purpose.

In many Russian cities district heating is a common feature that sees a local power plant supply up to around 250 MWe to the grid, as well as process heat to a communal system to warm homes, schools, factories and offices. These systems have traditionally relied on fossil fuels but will need to change in line with incoming goals to gain in efficiency and to decarbonise, as set out by a Presidium of the State Council which specifically mentioned nuclear as a potential technology.

In response, NIKIET has completed the detailed design of the VK-300 reactor.

VK-300 is a boiling water model with 750 MW thermal capacity and 150-250 MW electric depending on the required mix of heat and power. It uses proven components, including similar fuel elements to the large established VVER pressurized water design.
