Established in 1956, NIIP designs and tests instruments and electronic equipment to measure radiation, creates physical and mathematical models to determine the effects of varying types of radiation exposure on equipment, develops automated instruments for taking measurements during radiation research, and conducts surveys of ionizing radiation fields at nuclear installations. 1 The Institute has one operational research reactor, which is powered by highly-enriched uranium (HEU). 2 For an overview of Russia’s HEU policy and the full list of Russia’s facilities using HEU, see the Russia Civilian HEU profile.


Radioactivity: The spontaneous emission of radiation, generally alpha or beta particles, often accompanied by gamma rays, from the nucleus of an unstable isotope.
Research reactor
Research reactor: Small fission reactors designed to produce neutrons for a variety of purposes, including scientific research, training, and medical isotope production. Unlike commercial power reactors, they are not designed to generate power.
Highly enriched uranium (HEU)
Highly enriched uranium (HEU): Refers to uranium with a concentration of more than 20% of the isotope U-235. Achieved via the process of enrichment. See entry for enriched uranium.
