State Scientific Institution "JIPNR-Sosny" NAS of Belarus


About us

The Joint Institute for Power and Nuclear Research – Sosny of the National Academy of Sciences of Belarus is the legal successor of the Nuclear Power Engineering Institute of the BSSR Academy of Sciences, founded on June 22, 1965.

The first Institute Director was Academician A. K. Krasin

Andrew Kapitonovich Krasin (21.05.1911 – 28.03.1981) is a great nuclear power energy scientist. He was an academician of National Academy of Sciences of Belarus (1960), doctor of physical and mathematical sciences (1955), professor (1957). He was awarded by the name of Honored Science and Techniques Worker of BSSR (1968).He participated in Great Patriotic War. He graduated Tomsk University in 1934. In period 1934-1940 he worked in Siberian physical and technical Institution and in Tomsk University as senior lecturer. In 1945 A.K. Krasin worked in I.V. Kurchatov laboratory.

From 1946 he worked in Obninsk Physical-Energetic Institution – as a scientific vise-director, then in 1956-1959 as director and in 1959-1961 as a researcher. In 1961 he becomes a leader of atomic energy department in the Institute of Energy of AS BSSR. In 1965-1977 he was a director of Nuclear Energy Institution of AS BSSR. Simultaneously, he was Academician-Secretary of Physical-Engineering Science Department of AS BSSR. From 1977 he was a head of hydrogen energetics laboratory of Heat and Mass Transfer Institution of AS BSSR.

Scientific research of Krasin was devoted to physics of interactions between radiation and substances, development and building nuclear power stations. He participated in creation of the first in the world Beloyarsk nuclear power plant (Obninsk). He participate also in development of reactors and heat-transfer agents

He was ordered by Lenin premium in 1957 for the development of the first in the world nuclear power plant. He is an author of more than 350 scientific works and special developments, 3 books and several inventions.

A. K. Krasin was ordered by Lenin order (1958), October revolution order (1971), order of Patriotic War II-degree (1945) and several medals.

Main publications: Energetic nuclear reactors, M. 1957; Atomic electrical power stations, M. 1959; Reactors of nuclear power plants, Minsk, 1971.

By that time the Institute had commissioned an on-site research nuclear reactor IRT-1000 the capacity of which was subsequently increased to 4,000kW; a laboratory for physical capacity reactors and a test building with thermophysical experimental installations. Works on creating a radiochemical laboratory with hot cells for operations with highly- active materials and substances were close to completion. In 1973, a Special Design Bureau with pilot production facilities was founded and the first line of experimental production facilities was constructed, to include special stands, installations and new technological processes for manufacturing and testing nuclear power equipment. Since the foundation of the Nuclear Power Engineering Institute and until the Chernobyl accident, the Institute primarily specialized in such basic and applied research areas as material- radiation interaction, development of gas-cooled slow- and fast-neutron nuclear reactors and application of ionizing radiation sources in the national economy. Assisted by over 150 organizations and enterprises of the USSR in 1985 the Institute created and started-up the world’s first mobile nuclear power plant Pamir-630D with a thermal power of 10 MW (electric output of640 kW) with dissociated coolant and N2O4-based nitrine working fluid. The plant was to be used as an independent electric power source for mobile and stationary facilities located in poorly accessible regions of the USSR. Simultaneously, research and design work was underway to design an NPP with a fast breeder reactor with dissociated coolant. There was developed an engineering design of a pilot nuclear power station with a fast breeder reactor BRIG-300 (electric output of 300 MW). In those years the Institute became one of the USSR’s major research centers for nuclear power. Immediately after the accident at the Chernobyl Nuclear Power Station the Institute became actively involved in solving such critical problems as identifying levels of radiological contamination of the country’s territory with radio-nuclides and exposure levels of the population in affected areas, testing domestically-produced foodstuffs for radiological contamination which played an important role in determining the strategy and tactics of radiological safety activities. At present the Institute’s staff consists of 380 employees including 15 researchers with Doctor of Sciences degreе and 45 with Ph. D.
