EDUCATION Ph.D., Technical Sciences, I. V. Kurchatov Institute of Atomic Energy, Moscow, 1990 M.S., Material Science, Moscow Institute of Engineering and Physics (MIFI), Moscow, 1982. MEMBERSHIP IN PROFESSIONAL SOCIETIES International Group on Radiation Damage Mechanism (IG-RDM) American Society for Testing and Materials (ASTM) HONORS AND AWARDS 1994 Significant Contribution Award by the Materials Science and Technology Division of the American Nuclear Society The Premium of the Council of Ministers of the U.S.S.R. in the field of science and technology for creation of the scientific basis and implementation of annealing of VVER-440 reactor pressure vessels to enhance the safety of nuclear power plants, 1991 Title of Senior Research Scientist from the Academy of Science of the U.S.S.R,, 1990 The First Premium in the field of radiation damage of materials by the Ministry of Atomic Energy and Industry of the U.S.S.R., 1987 I. V. Kurchatov prize in research field by Institute of Atomic Energy (currently Kurchatov Institute), 1986 EXPERIENCE 1997 to Present - Task Leader, U.S. Nuclear Regulatory Commission (NRC) Heavy-Section Steel Irradiation Program, ORNL 1992 to 1997 - Assignment at Oak Ridge National Laboratory for Oak Ridge Associated Universities. Engaged in studies as one of the task leaders for the Heavy-Section Steel Irradiation Program sponsored by the NRC 1982 to 1992 - Russian National Research Center, "Kurchatov Institute," Reactor Materials Division; originally as associate Researcher and later as Senior Research Scientist. Studied the effect of radiation exposure on the mechanical properties of reactor vessel steels; specific tasks included investigation of the effect of annealing on the recovery of materials properties of the steel. Took part in almost all annealing of VVER-440 vessels in Russia and Eastern Europe as scientific supervisor. 1991 to 1992 - Associate Professor (docent) at Moscow Institute of Engineering and Physics (part- time). Taught graduating students on investigation of mechanical properties of irradiated materials. SCOPE OF RESEARCH Studying the effects of radiation exposure on degradation of mechanical properties, fracture toughness and microstructure of low-alloyed steels Establishing of temperature-time recipe for thermal annealing beneficial for recovery of irradiated reactor pressure vessel steels Exploring the applicability of nonstandard specimen and/or technique to characterization of fracture toughness and mechanical properties of irradiated steels Fracture toughness studies of low-alloy pressure vessel steels to provide engineering data for structural integrity assessments of nuclear reactor vessels
