Nuclear science and engineering

MIT researchers have developed a framework to determine what is needed to make fusion energy commercially viable, writes World Nuclear News (WNN). “The parameters in the framework describe engineering features of the fusion power plant such as power density, the efficiency of converting fusion power into an economic product, and the durability of components used in the energy conversion, in addition to costing and market parameters that assess the expenses and returns from invested capital,” explains WNN.  

Prof. Dennis Whyte and Prof. Andrew Lo have built a framework to mitigate the economic challenges of fusion power, writes Interesting Engineering’s Ameya Paleja. “While there are multiple approaches to building a nuclear fusion facility, Whyte and colleagues believe that at the end of the day, the facility should be in a position to generate more money that has gone in to building and operating it, otherwise it won’t last for long,” writes Paleja. 

Bob Mumgaard PhD ‘15, co-founder and CEO of MIT spinout Commonwealth Fusion Systems, speaks to Fast Company’s Adele Peters about building his company’s first power plant, set to come online in the 2030s in Virginia. “To make fusion into more than just the first plants, it has to be an industry and there’s multiple parts of that,” says Mumgaard. 

Fast Company’s Adele Peters spotlights “Project Obsidian,” a new geothermal power plant developed by MIT spinout Quaise Energy. The findings of former Senior Research Engineer Paul Woskov helped Quaise develop their tech. “Paul’s epiphany was realizing that if we can use the same energy to heat plasmas to millions of degrees Celsius to get fusion, why not use that for heating and drilling through rock at a much more modest temperature?” says Matthew Houde, Quaise co-founder.  

Associate Prof. Areg Danagoulian has developed a satellite equipped with specialized neutron detectors that he hopes will fill the gaps in the 1967 Outer Space Treaty, which bans nuclear weapons in space without a way to verify satellites are not carrying them. “[I]f the concept proves to be practical enough to someone in charge, it could finally give us a way to verify that there really aren’t any nukes floating precariously over our heads,” writes Luis Prada for Vice. 

Financial Times reporter Michael Peel features CubeSat, a proposed satellite sensor by Associate Prof. Areg Danagoulian, able to identify hidden nuclear weapons in space.  “If one state suspects another of placing a nuclear weapon in orbit, the absence of a verification mechanism makes the crisis harder to manage,” says Danagoulian. “If a bad-faith actor knows that their attempt will be discovered via inspection, they will be more likely to decide it's not worth pursuing.” 

Gizmodo’s Ellyn Lapointe reports on a new paper from Associate Prof. Areg Danagoulian, which offers a  solution to verifying satellites aren’t carrying hidden nuclear weapons in space: an inspector satellite able to indicate the presence of uranium from neutron signals via sensor technology. Danagoulian’s proposal seeks to fill the gaps of The Outer Space Treaty (OST), established in 1967 and signed by 118 countries to ban nuclear weapons in space, which “has always lacked robust means of verification for space-based nuclear threats,” says Danagoulian. 

In a new study, Associate Prof. Areg Danagoulian proposes a satellite-based sensor that could monitor suspicious craft for signs of nuclear activity in space with 99% accuracy, reports Andrew Paul for Popular Science. “You can fake intelligence, but you can’t fake physics,” says Danagoulian. “The goal right now is to get national labs to use this work for their own research, and to get policymakers to seriously consider this technology as a potential part of national technical means.” 

Scientific American’s Adam Kovac highlights a paper by Associate Prof. Areg Danagoulian that proposes a satellite to detect and police hidden nuclear weapons in space by detecting spallation, the ejection of neutrons, from the bombardment of high energy protons, and uranium atoms. “If you detect those neutrons, that itself can be a telltale sign that there is an unusual amount of uranium on the satellite, and it’s most likely to be a nuclear weapon,” Danagoulian says.

For Scientific American’s special section “The Young American Scientists” Bob Mumgaard PhD ‘15, co-founder and CEO of Commonwealth Fusion Systems, speaks with Tara Haelle about the commercialization of fusion science and how automated tools have accelerated research. “Whether in areas such as fusion—or in drugs by design for diseases such as Alzheimer’s and Parkinson’s or in [the creation of] materials we never thought possible—our ability to use new tools to tackle some of these big, meaty problems is super exciting,” says Mumgaard. 

In a series of papers published in the Journal of Plasma Physics, researchers from MIT, Commonwealth Fusion Systems (CFS) and other universities were able to validate the science and feasibility behind CFS’ plans to build a 400-megawatt fusion power plant, reports Timothy Gardner for Reuters. 

Postdoctoral Fellow Florian Galleri speaks with Associated Press reporter Sylvie Corbet about France’s move to align “its nuclear deterrent strategy more closely with European allies while keeping full control over any strike decision.” Galleri says “the strategic backing intended to integrate French nuclear deterrence into a collective European defense framework necessarily requires a degree of coordination and joint planning.” 

Prof. Jacopo Buongiorno speaks with NBC News about the U.S. government airlifting parts of a nuclear reactor across three states and the future of nuclear power in America. “[It is] very positive. There is finally a sense of urgency and a push to increase our reliance on nuclear,” says Buongiorno. “I think nuclear has a lot of attractive features as an energy source. As I said earlier, it’s clean, it’s compact, it’s reliable.” 

Fast Company reporter Adele Peters spotlights Electrified Thermal Solutions, an MIT startup that has developed a new “thermal battery” that could be used to help power factories manufacturing energy-intensive materials like steel and cement. “The battery uses power from the grid to heat its custom bricks when electricity is cheap,” explains Peters. “When a factory needs hot air later, it’s provided by the superheated bricks.” 

Brian Bergstein at The Boston Globe speaks with Bob Mumgaard SM '15, PhD '15, CEO of MIT spinout Commonwealth Fusion Systems, about the company’s efforts to advance fusion technologies.  “When the federal government said in 2012 that it would cut funding for the experimental fusion reactor on campus, the MIT researchers took that as an opportunity to develop new fusion techniques — which eventually formed the basis of CFS’s plans,” writes Bergstein.
