In context: how this plant compares
At 110 MW, Ust-Kuyga nuclear power plant is below the median nuclear plant in Russia (2,364 MW). Technically it is described as pressurized water reactor. Its current lifecycle status is “Pre 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.
