WebJun 23, 2024 · Mohamed Abdou, a nuclear engineer at the University of California, Los Angeles, believes future reactors may operate less than 5% of the time. Compare this, he says, with today’s fission reactors. They can keep running even when individual fuel rods fail. Cranes can swap out fuel rods in just a couple of days. WebThis is fuel designed for thermal-neutron reactors, virtually 100% of the world's installed nuclear power today. If you want to breed with 238-U, you need fast neutrons, which means radically different reactor designs.
