In context: how this plant compares

At 345 MW, Natrium nuclear power plant is below the median nuclear plant in United States of America (1,350 MW). Technically it is described as liquid-metal-cooled fast 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.
