Seversk nuclear power plant is a 2,775 MW nuclear power station in Tomsk, Russia. It is operated by Rosatom [100%]. Based on its capacity (estimated), it can supply roughly 6.3 million homes (estimated). It ranks #23 of 678 Russia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 18.3% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

At 2,775 MW, Seversk nuclear power plant is well above the median nuclear plant in Russia (2,400 MW). Technically it is described as pressurized water reactor. Its current lifecycle status is “Construction” — so it is not yet, or no longer, generating at full output. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 56.7°N — which shapes how much energy it can produce and how its output varies through the year.
