Researchers at MIT have developed a “new type of transistor using semiconductor nanowires made up of gallium antimonide and iridium arsenide,” reports Alex Knapp for Forbes. “The transistors were designed to take advantage of a property called quantum tunneling to move electricity through transistors,” explains Knapp.
Prof. Jacopo Buongiorno speaks with Nature reporter Davide Castelvecchi about how AI has increased energy demand and the future of nuclear energy.
Prof. Jacopo Buongiorno speaks with Nature reporter Michael Greshko about the reopening of Three Mile Island, a former Pennsylvania nuclear power plant that will now be used to generate power for artificial intelligence. “It’s further confirmation of the value of nuclear, and, if the deal is right — if the price is right — then it makes business sense, as well,” says Buongiorno.
Prof. Jacopo Buongiorno speaks with ABC News reporter Julia Jacobo about the reopening of Three Mile Island, a former Pennsylvania nuclear power plant, to generate power for artificial intelligence. “Since building a new nuclear power plant can be so time consuming and expensive, extending the license of current plants or refurbishing and restarting those that have been recently shutdown is a very attractive proposition,” says Buongiorno.
Graduate student Zoe Fisher speaks with Yusuf Khan of The Wall Street Journal’s about what inspired her to pursue a career in nuclear engineering, noting that being able to fight climate change firsthand is one of the key reasons she wanted to make a career in nuclear.. “It’s a cool thing to study that is going to have a lot of broader impacts,” Fisher says.
Writing for Nature, Marinko Sarunic and Cynthia Toth memorialize the life and work of Joseph A. Izatt PhD '91, who “had a special gift, and commitment, to reaching out and working with students and clinicians to create transformative technology." After undergraduate studies at MIT, Izatt focused on applied optics for his graduate work, with his mentors Prof. Michael Feld and Prof. James Fujimoto.
Research affiliate Thomas Neff, a physicist known for his proposal aimed at “reducing the global stockpile of nuclear weapons and helping stabilize the former Soviet Union,” has died at age 80, reports Harrison Smith for the Washington Post. Credited with the “Megatons to Megawatts” agreement, “Dr. Neff spent years working in arms control, nuclear weapons proliferation and uranium markets, bridging the divide between experts who specialized in the kind of highly enriched uranium used for warheads and the far less enriched version used for electricity generation,” Smith writes.
Research affiliate Thomas Neff, a physicist whose work with nuclear weapon conversion led to an agreement “that reduced nuclear threats and produced one of the greatest peace dividends of all time,” has died at the age of 80, reports William J. Broad for The New York Times. Neff’s idea of converting Soviet nuclear weapons into electricity used to power American cities “turned some 20,000 Russian nuclear arms into electricity, lighting billions of American lightbulbs.”
Prof. R. Scott Kemp and Principal Research Scientist Charles Forsberg speak with Verge reporter Justine Calma about the nuclear proliferation concerns raised by the higher concentrations of uranium used in next-generation nuclear reactors. “We need to make sure that we don’t get in front of ourselves here and make sure that all the security and safety provisions are in place first before we go off and start sending [high-assay low-enriched uranium] all around the country,” says Kemp.
Explaining China’s increasing advantage over the U.S. in fusion technology, Prof. Dennis Whyte is interviewed for a Wall Street Journal article by Jennifer Hiller and Sha Hua. Noting China took just 10 years to build world-class fusion research facilities, Whyte says “it was almost like a flash that they were able to get there. Don’t underestimate their capabilities about coming up to speed.”
MIT scientists have published a new study questioning the use of high-assay low-enriched uranium (HALEU) planned for next-generation U.S. nuclear reactors, writes Timothy Gardner for Reuters. "This material is directly usable for making nuclear weapons without any further enrichment or reprocessing," explains Prof. Scott Kemp, noting while the uranium is enriched to levels of up to 20%, compared with about 5% for most reactor fuel, 10% to 12% would be far safer.
Conner Galloway SB '08 SM '09 and Alexander Valys SB '08 lead Xcimer Energy Company, a startup seeking to provide economical nuclear fusion power and “pursuing what’s best described as a ground-up redesign of the underlying technology,” writes Tim De Chant for TechCrunch. “This is proven science,” Galloway, the CEO of Xcimer CEO, explains. “It’s just a matter of building a big enough laser, cheap enough laser and efficient enough laser.”
MIT spinoff Electrified Thermal Solutions is developing electrically charged bricks that generate and store heat as part of an effort to one day replace fossil fuels, reports Phil McKenna for Inside Climate News. “If you are running an industrial plant where you’re making cement or steel or glass or ceramics or chemicals or even food or beverage products, you burn a lot of fossil fuels,” explains Daniel Stack SM '17, PhD '21, chief executive of Electrified Thermal Solutions. “Our mission is to decarbonize industry with electrified heat.”
Prof. Jacopo Buongiorno talks with Steve Curwood of Living on Earth about new investments in nuclear power generation, advanced reactors and waste disposal. He notes roughly half the clean energy in the U.S. comes from nuclear, with great potential due to its adaptability. “The nice thing about nuclear is that it’s a fairly versatile energy source,” explains Buongiorno. “It can give you heat, if you want heat. It can give you electricity if you want electricity. It can give you hydrogen if you need hydrogen, or some kind of synthetic fuel for transportation."
Senior Lecturer John Parsons speaks with Grist reporter Gautama Mehta about the future of nuclear energy in the United States. “It’s also possible that nuclear, if we can do it, is a valuable contribution to the system, but we need to learn how to do it cheaper than we’ve done so far,” explains Parsons. “I would hate to throw away all the gains that we’ve learned from doing it.”
