Nuclear science and engineering

Graduate student Lt. Col. Jill Rahon, a war veteran and seasoned pilot, discusses her journey from her tours in Afghanistan to her research at MIT on engineering solutions for the enforcement of nuclear nonproliferation accords, writes Sam Cavanaugh for Hoodline. “The path Rahon has blazed is marked by courage and ingenuity, from deftly handling the controls of a Chinook helicopter over the treacherous terrains of Afghanistan to meticulously studying the nuances of resonance analysis to keep nuclear powers in check,” writes Cavanaugh. 

MIT irradiation facilities engineer Andriy Tuz and Prof. Jacopo Buongiorno speak with Jennifer Hiller of the Wall Street Journal about Tuz’s path from Ukraine to MIT. Tuz joined the Institute “through the U.S. government’s Uniting for Ukraine program, which provides a way for Ukrainian citizens displaced by the war to stay temporarily in the U.S.,” writes Hiller.

ClimateWire reporter John Fialka writes that MIT engineers have developed a new process to convert carbon dioxide into a powder that can be safely stored for decades. “The MIT process gets closer to an ambitious dream: turning captured CO2 into a feedstock for clean fuel that replaces conventional batteries and stores electricity for months or years,” writes Fialka. “That could fill gaps in the nation's power grids as they transition from fossil fuels to intermittent solar and wind energy.”

Prof. Jacopo Buongiorno speaks with Danny Lewis, host of The Wall Street Journal’s “Future of Everything” podcast, about the future of nuclear power plants. “As countries, regions, businesses contemplate their future plans for reducing carbon emissions, nuclear is one technology that they have got to consider,” says Buongiorno. “It's an incredibly dense energy source, so you don't need a big supply chain that continuously feeds the power plant with fuel, the same way that you would with coal, for example. Also, the machine itself, the reactor is very, very compact.”

Prof. M. Taylor Fravel speaks with NPR reporter Emily Feng about a new Pentagon report highlighting China’s accelerated efforts to develop a nuclear arsenal. “It’s a complete transformation of China's approach to nuclear weapon,” says Fravel. “[The information found in the report] confirms “the rapid modernization foreshadowed several years ago is on track.”

Graduate student Kaylee Cunningham speaks with CBS Boston about her work using social media to help educate and inform the public about nuclear energy. Cunningham, who is known as Ms. Nuclear Energy on TikTok, recalls how as a child she was involved in musical theater, a talent she has now combined with her research interests as an engineer. She adds that she also hopes her platform inspires more women to pursue STEM careers. “You don't have to look like the stereotypical engineer,” Cunningham emphasizes.

Dan Stack PhD ’20 speaks with TechCrunch reporter Tim De Chant about his startup Electrified Thermal Solutions, which is developing electrified firebricks to help decarbonize building materials.  

Prof. Jacopo Buongiorno speaks with NBC reporter Catherine Clifford about the future of nuclear energy in the United States. “The US may catch up if the new technologies being developed here — small modular reactors and microreactors above all — will prove to be technically and commercially successful, which is currently uncertain,” says Buongiorno.

In an article he co-authored for Fortune, postdoctoral associate Matthew Hughes explains how extreme heat affects different kinds of machines. “In general, the electronics contained in devices like cellphones, personal computers and data centers consist of many kinds of materials that all respond differently to temperature changes,” they write. “So as the temperature increases, different kinds of materials deform differently, potentially leading to premature wear and failure." 

Prof. Tracy Slatyer and Prof. Janet Conrad speak with Scientific American reporter Clara Moskowitz about their favorite discoveries in the field of physics. Slatyer notes that “the accelerating expansion of the universe has to be a strong contender.” For Conrad, “I think my favorite event in physics was the prediction of the existence of the neutrino [a subatomic particle with no charge and very little mass] because so much of our fundamental approach to physics today grew out of that moment.”

In this video for Wired, Prof. Anne White explains the nature of nuclear fusion in five levels of increasing difficulty to a child, a teen, a college student, a grad student, and an expert. “Fusion is so exciting because it is extraordinarily beautiful physics, which underpins some of the most basic processes in our universe," says White. “Nuclear processes have a tremendously valuable application for humankind, a virtually limitless, clean, safe, carbon-free form of energy.”

Researchers from MIT’s Plasma Science and Fusion Center and Commonwealth Fusion Systems (CFS) are using high-temperature superconducting tape as a key part of the design for their tokamak reactor, reports Tom Clynes for IEEE Spectrum. The researchers believe that “this novel approach will allow it to build a high-performance tokamak that is much smaller and less expensive than would be possible with previous approaches,” Clynes notes.

Jacob DeWitte SM ’11, PhD ’14 co-founded Oklo, a startup working toward developing small nuclear power plants to deliver emission-free, reliable, and affordable power, reports Heather Wishart-Smith for Forbes.

Commonwealth Fusion Systems, MIT’s Plasma Science and Fusion Center and others are working to build SPARC, a prototype device that aims to extract net energy from plasma and generate fusion power, reports Philip Ball for Scientific American. “SPARC will be a midsize tokamak in which the plasma is tightly confined by very intense magnetic fields produced by new high-temperature superconducting magnets developed at MIT and unveiled in 2021.”  

Writing for The Boston Globe, Prof. Emeritus Ernest Moniz writes that the National Ignition Facility’s fusion energy advancement “is exciting because when the journey from science demonstration to a commercially viable power plant is completed, the electricity grid will be revolutionized.” Moniz continues, “To meet widely accepted climate objectives, we must double the clock speed of the clean energy innovation process.”
