While flipping through the course catalog at the University of Massachusetts–Amherst, I read that civil engineers can design amusement park rides. I was instantly inspired and chose my major because I wanted to design something for Walt Disney World. After college, I started my dream job at Simpson Gumpertz & Heger, which is famous for designing Spaceship Earth at Epcot Center, a celebration of human innovation, communication, and the progress of civilization. This was a win.

My introduction to nuclear

During my first two years at SGH, I experienced all aspects of working in the Engineering Mechanics & Infrastructure group, from analyzing structural failures to studying pipelines and modeling antennas. In 2006, I worked on my first nuclear facility. It consisted of structural analysis and design of the Integrated Waste Treatment Unit at Idaho National Laboratory.

LEGO model of Swiss research reactor needs supporters!

November 12, 2024, 9:30AMANS Nuclear Cafe

A fascinating interactive LEGO model of CROCUS, a zero-power, uranium-fueled, water-moderated fission reactor used for teaching and research purposes at Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL), has been created by Vincent Lamirand, a scientist at EPFL’s Laboratory of Reactor Physics and Systems Behaviour. Lamirand, who teaches courses on reactor experiments and radiation detection and leads the experimental research with CROCUS, is using the model to teach his students about the reactor. He is hoping that the LEGO company will eventually produce his model for the public to purchase.

History in the making: D&D begins on Three Mile Island-2

Constellation Energy has announced that it will seek to restart Unit 1 of the Three Mile Island nuclear power plant in Pennsylvania as part of an agreement with Microsoft to power that company’s data centers. Given the growing interest by tech companies in using clean, reliable nuclear power to meet their growing energy demands, the September 20 announcement to reopen TMI-1, which was shut down and defueled in 2019, was not a huge surprise.

UMich leads Space Force institute on hybrid nuclear power and propulsion concept

Seeking spacecraft that can “maneuver without regret,” the U.S. Space Force is investing $35 million in a national research team led by the University of Michigan to develop a spacecraft with an onboard microreactor to produce electricity, with some of that electricity used for propulsion. But this spacecraft would not be solely dependent on nuclear electric propulsion—it would also feature a conventional chemical rocket to increase thrust when needed.

New work for old FLiBe? DOE considers reuse of molten salt reactor coolant

FLiBe—a mixture of lithium fluoride and beryllium fluoride—is not an off-the-shelf commodity. The Department of Energy suspects that researchers and reactor developers may have a use for the 2,000 kilograms of fluoride-based salt that once ran through the secondary coolant loop of the Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory.

Federal and contractor officials, community leaders, and educators gathered in Knoxville, Tenn., on October 29 for a roundtable event focused on ensuring the Oak Ridge Office of Environmental Management (OREM) and its partners have the resources and infrastructure needed to support a robust, talented workforce in the years ahead.

Industry experts discuss nuclear’s role in powering data centers, meeting climate goals

November 7, 2024, 9:30AMANS News

As a primer to the American Nuclear Society Winter Conference and Expo, ANS Executive Director/Chief Executive Craig Piercy hosted a panel discussion titled “The State of Nuclear,” sponsored by the ANS Trustees of Nuclear. The October 29 discussion, the first in a two-part series, featured five thought leaders from the nuclear community as they reviewed the current state of nuclear power. The second panel will take place during the ANS Winter Conference in Orlando, Fla., on November 18.

The discovery of a rare species of bee by environmental regulators has blocked the plans of tech conglomerate Meta to build an artificial intelligence data center powered by nuclear energy—at least temporarily. Numerous media outlets, including Popular Science, have reported that the unnamed species of bee was detected by regulators who were surveying the land designated for the new data center—land that is located next to an unnamed nuclear power plant from which Meta had planned to obtain electricity.

Uranium prices have fallen to their lowest level in more than a month, to just under $79 per pound, on Friday, November 1, according to analyst website Trading Economics. The lower prices, according to the site, are related to recent evidence of increased supply. This contrasts with the longer-term expectations of bullish demand and higher prices.
