Landmarks of OKBM History

The enterprise was founded on December 27, 1945, when the USSR Government Resolution formed the "OKB for design of special machines" on the basis of Gorky Artillery Plant No. 92 to fulfill the tasks under the Soviet "Atomic Project". Beginning from the late 1940's, OKB takes an active part in development of the first production reactors and in the 1950's it participates in development of reactors for the Navy and civil fleet. In 1960, OKBM received the Top State Award, Order of Lenin, for taking part in development of the nuclear power plant for the first in the world civil nuclear ship, the "Lenin" icebreaker.  
In 1963, because the OKB research area and workscopes of reactor development  for various applications had been expanded substantially, the USSR Government made a decision to detach OKB from the Gorky Artillery Plant. January 1, 1964 OKB became an independent organization to be a part of the USSR State Committee for the Use of Nuclear Energy. January 1, 1967, the enterprise received an open name "Experimental Design Bureau for Machine-Building" (OKBM).  
Further on, OKBM was part of the USSR Ministry of Medium Machine Building, Russian Federation Ministry for Atomic Energy, Federal Agency for Atomic Energy. At the present time, JSC Afrikantov OKBM is part of the integrated company JSC Atomenergoprom that consolidates civil assets of the Russian nuclear industry and provides the complete production cycle for nuclear applications ranging from uranium mining to NPP construction and electricity generation. JSC Atomenergoprom is part of the Rosatom State Corporation for Atomic Energy. In 1998, OKBM was named after I.I. Afrikantov, who was OKBM Chief Designer (from 1951) and Head (from 1964 to 1969). In 2004 OKBM was given the status of a Federal Scientific and Production Center (Arckhangelsk Region) by the RF Government Resolution.  
In total about 500 nuclear reactors and steam generating plants, hundreds of pieces of complex process equipment were constructed and successfully operated with our enterprise actively taking part. These achievements were to a great extent related to Academician F.M. Mitenkov's indefatigable creative and organizational activity, who was the OKBM Leader for 28 years (1969 – 1997) and made an enormous contribution to develop the unique experimental and production bases at OKBM. He is the one owing to whom the enterprise became the renowned scientific and production center of nuclear engineering.  In 1990's, the enterprise together with the entire nuclear sphere was living through the hard times of depression when orders were reduced in the civil and military nuclear industry. Facing the growing financial and economic hardships, OKBM leadership had to adopt an adequate business strategy under the new economic conditions. The strategy was based on the active approaching the high-tech market mostly with accomplished, OKBM-manufactured products. The goals were also to expand the research area for nuclear industry and non-nuclear market, active involvement of foreign customers. The program, of which development and implementation is related to the latest OKBM leaders, and V.I. Kostin, was supported by the team and quickly produced the expected results.  
In 2003, new stage began in OKBM's active development and steady growth of its financial and economic performance. The enterprise embarked on the extensive program to restructure and upgrade the production facilities aiming at achievement of new business capabilities and extension of the range of products and services.  
At the present time, OKBM is one of the leading design organizations in Rosatom State Corporation, large scientific and industrial center of nuclear engineering with a versatile design team and its own research, experimental and production base. OKBM scientific and production potential makes it possible to perform all types of activities to develop various reactor plants and the entire range of equipment for them including design documents, required analyses, R&D, manufacturing and testing of experimental samples to master the industrial production technology, fabrication and supervised installation of standard equipment, its preoperational adjustment and comissioning, maintenance of equipment at operating facilities and decommissioning.  
As part of implementation of the Federal Target Program for Development of Nuclear Industry in Russia, OKBM takes an active part in development of a number of next generation power units as the Chief Designer and single-source manufacturer of reactor plants. They include:  
- BN-800 power unit based on the advanced sodium-cooled fast reactor with uranium-plutonium fuel and enhanced nuclear fuel breeding. The 880 MW(e) BN-800 power unit is under construction at the Beloyarsk NPP;
- floating power unit based on the commercially available icebreaker reactor KLT-40S for heat and electric power supply to isolated consumers in remote Northern and Eastern areas of Russia. The 70 MW pilot floating nuclear power unit is currently being constructed at “Baltiysky Zavod” in Saint Petersburg.  
The enterprise also takes an active part in development of other objects for nuclear applications in Russia and abroad, co-operates with IAEA, national laboratories and companies in China, India, USA, Republic of Korea, and France.  
OKBM’s main strength is its employees who possess great experience in development of a wide spectrum of nuclear power engineering devices, unique technologies, original engineering knowledge and solutions. About 4000 people work at OKBM, including over 1600 design engineers, technologists and test engineers. Among the employees, there is two Members of the Russian Academy of Sciences, 23 Doctors and 72 Candidates of Sciences. OKBM Director's Scientific Advisor, Academician F.M. Mitenkov, was awarded with the international "Global Energy" Prize in 2004 for his immense contribution to the development of physical and technological fundamentals and creation of fast neutron reactors. OKBM was awarded with the Order of Lenin in 1960 and the Order of October Revolution in 1985 for the immense contribution to the development of nuclear technologies.  
The title of Lenin Prize Winner was awarded to 14 OKBM employees, the title of State Prize Winner was awarded to more than 40 employees; 3 employees were awarded with the title of "Hero of Socialist Labor" for the outstanding achievements in the development of new technologies. The title of the "Honored Designer of RF" was awarded to 20 employees.
