The Kola Nuclear Power Plant (Russian: Кольская АЭС [About this sound pronunciation ]), also known as Kolsk NPP or Kolskaya NPP, is a nuclear power plant located 12 km away from Polyarnye Zori, Murmansk Oblast in north-western Russia.

The Phase 1 (No. 1 and 2 reactors) at the Kola NPP went online in 1973 and 1974, respectively, and are part of Russia’s first generation of PWR reactors (the VVER 440/230 type). The Phase 2 (No. 3 and 4 reactors) went online in 1981 and 1984 with the improved VVER 440/213 type.

Phase 1 reactors were designed to work for 30 years and were originally slated to be shut down in 2003 and 2004. However the shutdown did not happen. Instead, the operational life spans of the reactors were extended, after a massive safety upgrade effort that included about 200 safety systems upgrade projects and was financed in part by the governments of Norway, Sweden, Finland and USA.
