Leningrad NPP is a 4,376 MW nuclear power station in Leningrad, Russia. It is operated by JSC "Concern Rosenergoatom". Based on its capacity (estimated), it can supply roughly 9.9 million homes (estimated). It ranks #11 of 678 Russia power plants by installed capacity. Commissioned in 1974, it is around 52 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 18.3% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

At 4,376 MW, Leningrad NPP is well above the median nuclear plant in Russia (2,400 MW). Technically it is described as light water graphite 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.

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 59.9°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).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #6 largest nuclear power plant of 28 in Russia by capacity.
Russia has 28 nuclear power plants in this dataset, together about 68,383 MW of capacity.
