  • 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.
