Qinshan 2 is a 4,101 MW nuclear power station in Zhejiang Sheng, China. It is operated by China National Nuclear Corporation (CNNC). Based on its capacity (estimated), it can supply roughly 9,237,795 homes (estimated). It ranks #30 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 30.4°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 32% 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: 37/100 — 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.
