NuclearBusanSouth Korea

Kori is a 3,137 MW nuclear power station in Busan, South Korea. It is operated by Korea Hydro and Nuclear. Based on its capacity (estimated), it can supply roughly 7,066,316 homes (estimated). It ranks #10 of 204 South Korea power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 29.6% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

Local climate & thermal context

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 35.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 9% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 47/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
