Namie-Odaka nuclear power plant — Japan

Namie-Odaka nuclear power plant is a 825 MW nuclear power station in Fukushima Prefecture, Japan. It ranks #118 of 692 Japan power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 9.1% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

In context: how this plant compares

At 825 MW, Namie-Odaka nuclear power plant is below the median nuclear plant in Japan (2,070 MW). Technically it is described as advanced boiling water reactor. Its current lifecycle status is “Cancelled” — 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.
