In context: how this plant compares

At 1,200 MW, Clinch River SMR nuclear power plant is below the median nuclear plant in United States of America (1,350 MW). Technically it is described as boiling 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
