|Other Name:||(Национальный исследовательский центр Курчатовский институ) Петербургский институт ядерной физики им. Б.П. Константинова, ПИЯФ, part of the National Research Center Kurchatov Institute|
|Location:||Gatchina, Leningrad Oblast|
|Subordinate To:||Russian Academy of Sciences|
Founded in 1956 as a branch of the Ioffe Physico-Technical Institute, PNPI became an independent entity in 1971.  The Institute, which is a part of the Russian Academy of Sciences, is a state research center. and is one of the four organizations comprising the pilot cooperation project at the National Research Center Kurchatov Institute, established in 2009. 
PNPI conducts research on neutron physics, high energy physics, theoretical physics, and molecular and radiation biophysics. Its primary activities in the area of nuclear physics include proton and small-angle diffraction scattering. It also conducts applied research in engineering, medicine, and ecology. 
The institute is home to a critical assembly and two research reactors, all of which are HEU-powered. The VVR-M reactor, commissioned in 1959, is one of the oldest in Russia. In turn, the PIK high-flux research reactor is Russia's newest research reactor.  The startup of the PIK has been repeatedly delayed.  For an overview of Russia's HEU policy and the full list of Russia's facilities using HEU, see the Russia Civilian HEU profile.
