Astravets nuclear power plant is a 2,388 MW nuclear power station in Grodno, Belarus. It is operated by Republican Unitary Enterprise "Belarusian Nuclear Power Plant" [100%]. Based on its capacity (estimated), it can supply roughly 5.4 million homes (estimated). It ranks #2 of 29 Belarus power plants by installed capacity. Commissioned in 2021, it is around 5 years old — recently built. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 36.6% of Belarus's electricity; the national grid averages 309 gCO₂/kWh (41.4% low-carbon) (2025).

In context: how this plant compares
Technically it is described as pressurized water reactor. 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 54.8°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
