Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
Keynotes Session

Session Chair:
Fan-Bill Cheung (PSU)
Dr. Robert (Bob) Salko performs research in the area of computational thermal hydraulics to support modeling and simulation of light water reactors and molten salt reactors. His primary focus has been on development of subchannel and system thermal hydraulics codes, which includes modeling of two-phase flow and heat transfer, coupling with other reactor modeling tools, deployment on high performance computing systems, and implementing quality assurance measures and releasing software for users in the nuclear community. Bob has been working at Oak Ridge National Laboratory for approximately ten years, where he has supported efforts in the US Department of Energy Consortium for Advanced Simulation of Light Water Reactor and Nuclear Energy Advanced Modeling and Simulation programs. Prior to that, Bob obtained his PhD in nuclear engineering from The Pennsylvania State University.
