Georgeta Radulescu is a research and development staff member in the Radiation Transport and Criticality (RTC) Group in the Nuclear Science and Technology Division. She received an M.S. degree in engineering physics from the University of Bucharest, Romania, in 1986 and M.S. and Ph.D. degrees in nuclear engineering from the University of Texas at Austin in 1997 and 2003, respectively. For her Ph.D. dissertation, she developed a method of generating space and energy-dependent variance reduction parameters for Monte Carlo shielding calculations using adjoint fluxes from three one-dimensional discrete ordinates calculations. Her prior work experience includes shielding design and dose rate evaluations for the proposed geologic repository at Yucca Mountain and reactor experiments and calculations for the 14-MW TRIGA material testing reactor at the Institute for Nuclear Research, Pitesti, Romania. Dr. Radulescu joined ORNL in August 2005, where she has been involved in research projects related to burnup credit for criticality safety calculations, such as sensitivity and uncertainty analysis of commercial reactor criticals, and the development of STARBUCS, a SCALE control module for automated criticality safety analyses using burnup credit. Her research interests include criticality safety, burnup credit, source terms and radiation shielding, and variance reduction methods for Monte Carlo dose-rate calculations.
