Changjiang is a 1,220 MW nuclear power station in Hainan, China. Based on its capacity (estimated), it can supply roughly 2,748,137 homes (estimated). It ranks #469 of 5,959 China power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 4.6% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 19.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 100% 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: 13/100 — this site sits in the bottom 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.
