Dr. David Grabaskas is a nuclear engineer in the Safety Analysis Section at Argonne National Laboratory. He is a graduate of Ohio State University, where he received his BS in Mechanical Engineering, and MS and PhD in Nuclear Engineering with a focus on reactor safety and risk assessment. His research included advanced reactor accident analysis and future, risk-based regulatory requirements.
Since joining Argonne National Laboratory, Dr. Grabaskas’s work has centered on the safety of advanced reactor designs, including techniques to analyze the reliability of new passive safety systems (i.e., systems that require little to no human action or electrical power). Many new reactor designs include passive safety systems as a way to decrease the reliance on operator actions and off-site electrical power during accidents like those experienced at the Fukushima Daiichi Nuclear Power Plant in Japan.
Dr. Grabaskas also explores new risk assessment approaches for advanced reactors, in preparation for future regulatory licensing and to allow risk-based design option comparison. Recently, he has also been involved with the assessment of risk for offshore oil and gas platforms as part of a review following the Deepwater Horizon oil spill. He is a member of the American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) Joint Standard Committee for probabilistic risk assessment of advanced (non-light water) reactors.
