Researchers at Idaho National Laboratory identified a topological Kondo insulating state in plutonium hexaboride by analyzing electron behavior at quantum scales. This study provides new data on how actinide materials respond to extreme radiation and temperature conditions. These findings may assist in the development of safer reactor designs and improved methods for monitoring the aging of nuclear materials.

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...

The findings of this research—which was published in the journal Physical Review Research and supported with funding from the Department of Energy's Office of Science—has implications for the nuclear power industry. According to the investigators, the study could lead to practical developments that improve the safety and security of nuclear reactors and extend the lives of nuclear materials.
