The nuclear power station Obninsk (Russian: Обнинская АЭС, Obninskaja AES) was a part of the science city Obninsk, about 110 km southwest from Moscow. It was the first civilian nuclear power station in the world.[1] The plant is also known under the name APS-1 Obninsk (Atomic Power Station 1 Obninsk).



The reactor AM-1 ("Атом Мирный", Russian for Atom Mirny, or "peaceful atom"), had an electrical capacity of 6 MW but only produced around 5 MWe and thermal output was 30 MW, enough to power 2,000 modern homes for the time. It was a prototype design that used a graphite moderator and water coolant. This reactor was the forerunner of the further developed RBMK reactors.


Construction started on January 1, 1951, first startup was on June 1, 1954, and it was connected to the grid on June 26, 1954. For around 10 years, Obninsk remained the only nuclear power reactor in the Soviet Union, but continued after others were started up as well until April 29, 2002 when it was finally shut down.
