2nd nuclear fusion breakthrough could "pave way for future of clean power"
In December 2022, California scientists achieved a major breakthrough -- a nuclear fusion reaction that produced more energy than was used to create it. Scientists have done it again and this time their results produced even more energy. Professor Peter Hosemann, chair of nuclear and mechanical engineering at the University of California, Berkeley, joins CBS News to discuss the implications of this accomplishment.

State of Play

Nuclear energy provides almost 20 percent of the U.S. electricity supply. Advocates have called for an expanded role for nuclear as an emissions-free fuel source. But the economics of building new reactors are daunting. In addition, lingering safety concerns are an institutionalized part of the calculation of nuclear regulation, and highly radioactive nuclear waste remains a can that public officials have been inclined to kick down the road. The Energy Information Administration projects a sharp decline in nuclear power generation over the next decade, as new nuclear plants — two are planned — are more than offset by anticipated retirements of several operating reactors.
