Obninsk Institute for Nuclear Power Engineering (Russian: Обнинский институт атомной энергетики, traditionally abbreviated ИАТЭ) is an institution of higher education located in Obninsk. It began as a branch of the Moscow Engineering and Physics Institute in 1953 to provide specialists in the field of nuclear physics, reactor physics and reactor engineering for the Soviet Union's growing nuclear industry. The education was provided in close cooperation with nuclear-related research institutions in Obninsk. In 1985 the status was changed for Obninsk Institute for Nuclear Power Engineering to be the leading educational institution to train specialists for rapidly developing nuclear power in the former Soviet Bloc countries. In 2002 it acquired the status of the state technical university. In 2002-2009 it functioned as the Obninsk State Technical University for Nuclear Power Engineering. (Russian: Обнинский государственный технический университет атомной энергетики). In 2009 the Obninsk State Technical University for Nuclear Power Engineering was incorporated into the MEPhI National Research Nuclear University.

Obninsk Nuclear Power Plant (Russian: Обнинская АЭС, romanized: Obninskaya AES; ) was built in the "Science City" of Obninsk, Kaluga Oblast, about 110 km (68 mi) southwest of Moscow, Soviet Union. Connected to the power grid in June 1954, Obninsk was the first grid-connected nuclear power plant in the world, i.e. the first nuclear reactor that produced electricity industrially, albeit at small scale. It was located at the Institute of Physics and Power Engineering. The plant is also known as APS-1 Obninsk (Atomic Power Station 1 Obninsk). It remained in operation between 1954 and 2002. Its production of electricity for the grid ceased in 2002; thereafter it functioned as a research and isotope production plant only. According to Lev Kotchetkov, who was there at the time: "Although utilisation of generated heat was going on, and production of isotopes was even enhanced, the main task was to carry out experimental studies on 17 test loops installed in the reactor." The technology perfected in the Obninsk pilot plant was later employed on a much larger scale in the RBMK reactors.
