Vladimir Sobes

Research and Development Staff

Dr. Vladimir Sobes is currently a Research and Development Staff Member in the Nuclear Data and Criticality Safety group at Oak Ridge National Laboratory (ORNL). He received a Bachelor of Science degree in Nuclear Science and Engineering from the Massachusetts Institute of Technology (MIT) in 2011. After receiving his Doctoral degree from the same department two and half years later, Sobes began working at ORNL.As a nuclear data specialist, Dr. Sobes focuses his research on evaluation of nuclear data and propagation of nuclear data uncertainty for a wide range of end-use applications. The motivating factor for his research is to optimize the benefits of nuclear energy by increasing the safety of nuclear installations by providing better nuclear data and the understanding of how the uncertainty in nuclear data drives our ability to perform predictive modeling and simulation of nuclear systems. As a member of the nuclear data team at ORNL, Dr. Sobes shares responsibilities for the measurement, evaluation and validation of nuclear data for the international nuclear community, methods and code development for data applications, nuclear criticality safety analysis and reactor physics methods development. He is also the ORNL oversight technical lead for the design and construction of the University of Tennessee, Knoxville (UTK) sub-critical experiment facility.Dr. Sobes has demonstrated his flexibility and breadth of knowledge by taking on research outside the field of nuclear data. He has contributed to the United States (US) Department of Energy effort of evaluating the feasibility of direct disposal of spent nuclear fuel in a geologic repository. Early on in his career, Dr. Sobes conducted reactor analysis research and in recent years he took on a research project to develop new statistical inference methods for criticality calculations for the US Nuclear Regulatory Commission.Dr. Sobes has over 30 peer-reviewed publications in international journals, technical reports and conference proceedings. He is an active member of the American Nuclear Society serving on the Education Committee and the Technical Program Committee for the Nuclear Criticality Safety Division. He is also an active participant in two OECD/NEA1 Working Party on International Nuclear Data Evaluation Co-operation (WPEC) expert subgroups and group coordinator and founding member of a new subgroup on "Investigation of Covariance Data in General Purpose Nuclear Data Libraries."
