INL reports findings on unusual quantum behavior of plutonium
Scientists at Idaho National Laboratory have discovered that plutonium hexaboride (PuB6) displays a type of unusual quantum property called a topological Kondo insulating state. Materials with this property are neither typical electricity conductors nor regular insulators. Rather, they have exterior surfaces that strongly conduct electricity and interiors that block electricity.

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.
