NuclearCumbriaUnited KingdomAGRgas-cooled reactorRetired
Windscale AGR nuclear power plant is a retired nuclear power station in Cumbria, United Kingdom. Its current lifecycle status is “Retired” — so it is not yet, or no longer, generating at full output. It ranks #345 of 2,860 United Kingdom power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 12.4% of United Kingdom's electricity; the national grid averages 217 gCO₂/kWh (64.4% low-carbon) (2025).

In context: how this plant compares
At 36 MW, Windscale AGR nuclear power plant is below the median nuclear plant in United Kingdom (965 MW). Technically it is described as gas-cooled 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.
