Oak Ridge second-grader Amya is one smart cookie. She might not be able to give a textbook explanation of Isaac Newton’s third law of motion, but she knows how to apply it. In a recent classroom experiment, Amya grasped a billiard ball on one end of a long, narrow wooden cradle and struck a line of billiard balls in the cradle, sending the ball on the opposite end rolling. There you have it: For every action, there is an equal and opposite reaction. “I thought at first I was going to get all of the balls rolling, but I only got one,” Amya said. “I learned that.”
At this year's big supercomputing conference, SC19, the top of the list of the fastest machines in the world is unchanged, but there are a number of new technologies being talked about that portend the era of exascale computing—machines theoretically capable of a billion billion (i.e. a quintillion) calculations per second. As it has been since June of last year, the Summit computer at the Department of Energy's Oak Ridge National Laboratory (ORNL) is now on top of the Top 500 list, with a sustained theoretical performance of 148.6 petaflops on the High Performance Linpack test used to rank the Top500 list.
Isotek Systems, TerraPower, and the U.S. Department of Energy (DOE) today announced an innovative public-private partnership agreement that is providing extremely rare and unique isotopes for next-generation cancer research and treatment. DOE Deputy Under Secretary for Science T.L. Cubbage was joined by Senator Marsha Blackburn, U.S. Representative Chuck Fleishmann and senior leadership from TerraPower, Isotek, and Isotek’s parent companies— Atkins and SNC-Lavalin— at an event announcing this new beneficial and impactful arrangement.
As EM crews work to ensure the Oak Ridge National Laboratory’s (ORNL) Molten Salt Reactor Experiment (MSRE) remains safe until its decommissioning, they are also collaborating with academic and industry professionals interested in developing new molten salt reactors for nuclear power production. MSRE only operated from 1965 until 1969, but it earned an enduring legacy as an innovative technology concept. The reactor is shut down, but certain systems within the reactor building continue to operate to keep it safe and stable.
The contractor that runs Idaho National Laboratory is looking for private partners to build the first new test reactor in the United States in decades. The Versatile Test Reactor will have dedicated “fast-neutron-spectrum” testing capability, creating the conditions necessary to see how fuels, materials and sensors endure when battered with radiation in the form of fast neutrons. Assistant Secretary of Nuclear Energy Rita Baranwal, who ran the Gateway for Accelerated Innovation in Nuclear before being named to her current job a year ago, made the announcement Monday at an American Nuclear Society meeting in Washington, D.C. The Gateway for Accelerated Innovation in Nuclear is managed by INL.
Vistage Chair Kurt Greene recently launched a new chief executive board in the Knoxville market. The new Vistage members join a worldwide community of CEOs, executives, and business owners and will meet monthly to discuss business issues, share expertise and provide one another confidential help to achieve their goals. Greene is part of a community of more than 1,000 Chairs worldwide who lead local area boards, which total more than 23,000 members in 20 countries. The Knoxville area alone has 50 active and alumni members. Vistage is the oldest and largest peer advisor membership group.
DOE's Office of Environmental Management (EM) announced today the appointment of Jack Zimmerman as Director of the Environmental Management Consolidated Business Center (EMCBC), in Cincinnati, Ohio. Mr. Zimmerman is presently Manager of the Idaho Cleanup Project at the Idaho National Laboratory. For the past five years he has provided leadership in all aspects of the EM cleanup mission at the site, involving high level radioactive waste, low level and transuranic radioactive waste, spent nuclear fuel, and contaminated buildings, sites, and special nuclear material.
UniTech Services Group announces the hiring of Kevin Bumpus as Business Development Manager for government accounts. The talent acquisition signals the company’s expanding commitment to serving U.S. Department of Energy National Laboratories, designated Department of Energy (DOE) facilities and projects, as well as U.S. Department of Defense (DOD) groups.
Researchers at the Georgia Institute of Technology have achieved world record performance on the Summit supercomputer using a new algorithm for turbulence simulation. Turbulence, the state of disorderly fluid motion, is a scientific puzzle of great complexity. Turbulence permeates many applications in science and engineering, including combustion, pollutant transport, weather forecasting, astrophysics, and more. One of the challenges facing scientists who simulate turbulence lies in the wide range of scales they must capture to accurately understand the phenomenon
A team of four business students from Pellissippi State Community College took home first place in a national entrepreneurship competition last month for a new app that would make tutoring accessible to struggling high school students regardless of their ability to pay. Catherine Taylor, Joe Bedford, Jameisha Robinson and Vanya Malmstead from Pellissippi State were awarded $1,000 by the National Association for Community College Entrepreneurship for their business idea, the East Tennessee Tutor Network. Meanwhile, a second Pellissippi State team – comprised of Jeannette Green, Angela Heaverlo, David Scott and Tabitha Uremovich – finished in the top 3 of the online competition for their business idea, Kids Tech, which would provide tablets with educational apps free of charge for students in first through third grades.
