Nuclear waste could be a source of fuel in future reactors, say scientists.
American researchers are working on new systems to use waste products from the current fusion process to make a rare version of hydrogen called tritium.
The world is facing a growing need for electricity - from electric-powered cars to artificial intelligence (AI) data centers.
In theory, nuclear fusion - the process that fuses atoms together, releasing heat to turn generators - could provide huge energy supplies with minimal emissions.
But nuclear fusion is an expensive prospect because one of its main fuels is tritium.
Dr. Terence Tarnowsky, a physicist at Los Almos National Laboratory (LANL), New Mexico, explained that today’s nuclear power plants generate energy through a process cal
