Japan Power Demonstration Reactor nuclear power plant is a retired nuclear power station in Ibaraki Prefecture, Japan. Its current lifecycle status is “Retired” — so it is not yet, or no longer, generating at full output. It ranks #527 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 13 MW, Japan Power Demonstration Reactor nuclear power plant is below the median nuclear plant in Japan (2,070 MW). Technically it is described as boiling water reactor. Its lifecycle status is Retired; it no longer generates electricity. 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.
