President's ColumnThe value of “fluffy” stuffANS NewsDecember 16, 2020, 9:23AM|Mary Lou Dunzik-GougarMary Lou Dunzik-GougarYou know the old saying that those who can, do, and those who can’t, teach? Well, I say anyone thinking that way should be kept far away from students!In my time at Argonne National Laboratory and Idaho National Laboratory, I worked with incredible scientists and engineers doing cutting-edge research. Unfortunately, making progress in research is not always conducive to the education and training of those who haven’t yet gained the necessary expertise. And there is an interesting phenomenon that occurs the more one gains in education and experience: We tend to forget what we were like before, what it was like not to know everything we do now. More than one of my PhD colleagues at the national labs dismissed the education and outreach efforts that I pursued in my spare time: scouts, K-12 classroom visits, teacher workshops, science expos, etc., viewing any focus other than the truly technical as just “fluffy” and a waste of valuable time and effort.Go to ArticleTags:anldiscovery educationdoeeducationengineersinlk-12navigating nuclearscientiststeachingShare:LinkedInTwitterFacebook
Testing for Terrestrial Energy’s IMSR under way with research partnersNuclear NewsResearch & ApplicationsNovember 19, 2020, 7:00AM|Nuclear News StaffTerrestrial Energy and the Nuclear Research and Consultancy Group (NRG) have started a graphite irradiation testing program at NRG’s Petten Research Centre’s High Flux Reactor (HFR), located in the Netherlands. According to Terrestrial Energy, which is based in Ontario, Canada, the work is part of broader program of confirmatory testing of components and systems for the company’s Integral Molten Salt Reactor (IMSR), designed to produce both electricity and industrial heat.The testing program at NRG was planned to confirm the predicted performance of selected graphite grades throughout the seven-year cycle of an IMSR core. The testing was designed in cooperation with Frazer-Nash Consultancy, and will simulate IMSR core conditions at a range of operating temperatures and neutron flux conditions.“Our work with NRG at its Petten HFR facility is an important element of our overall IMSR test program, now well underway. The start of in-core irradiation tests speaks to our progress and comes after many months of prior work,” Simon Irish, CEO of Terrestrial Energy, said on November 12. “The NRG work also reflects an important feature of our testing strategy. That is to engage existing laboratories offering existing capabilities rather than build those in-house, a strategy that is essential for our early deployment schedule.”ExpandTags:advanced reactorsanlfuelmolten salt reactorsnrgterrestrial energyShare:LinkedInTwitterFacebook
Feature ArticleThe ongoing effort to convert the world’s research reactorsThe 40-year effort to make research reactors safer and more secure has led to the conversion of 71 reactors worldwide from HEU fuel to LEU.Nuclear NewsResearch & ApplicationsJuly 10, 2020, 2:17PM|Christina NunezThe Ghana Research Reactor-1, located in Accra, Ghana, was converted from HEU fuel to LEU in 2017. Photo: Argonne National LaboratoryIn late 2018, Nigeria’s sole operating nuclear research reactor, NIRR-1, switched to a safer uranium fuel. Coming just 18 months on the heels of a celebrated conversion in Ghana, the NIRR-1 reboot passed without much fanfare. However, the switch marked an important global milestone: NIRR-1 was the last of Africa’s 11 operating research reactors to run on high-enriched uranium fuel.The 40-year effort to make research reactors safer and more secure by replacing HEU fuel with low-enriched uranium is marked by a succession of quiet but immeasurably significant milestones like these. Before Africa, a team of engineers from many organizations, including the U.S. Department of Energy’s Argonne National Laboratory, concluded its conversion work in South America and Australia. Worldwide, 71 reactors in nearly 40 countries have undergone conversions to LEU, defined as less than 20 percent uranium-235. Another 31 research reactors have been permanently shut down.Go to ArticleTags:anlargonne national laboratoryatoms for peacedoeleumnsrnirr-1reduced enrichment for research and test reactorsresearch reactoru.s. doeShare:LinkedInTwitterFacebook
X-rays size up protein structure at the “heart” of COVID-19 virusNuclear NewsResearch & ApplicationsJune 29, 2020, 3:00PM|Nuclear News StaffOverlapping X-ray data of the SARS-CoV-2 main protease shows structural differences between the protein at room temperature (orange) and the cryogenically frozen structure (white). Graphic: Jill Hemman/ORNL, U.S. Dept. of EnergyA team of researchers at the Department of Energy’s Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease, the enzyme that enables the virus to reproduce.The X-ray measurements mark an important first step in the researchers’ ultimate goal of building a comprehensive 3D model of the enzymatic protein.ExpandTags:3d modelinganlcovid-19doeoffice of scienceornlsars-cov-2Share:LinkedInTwitterFacebook
General Chair’s Special Session: Advanced reactors in uncertain timesNuclear NewsJune 10, 2020, 5:28PM|Nuclear News StaffThe final plenary session of the American Nuclear Society's 2020 Virtual Annual Meeting was the General Chair’s Special Session, held on Wednesday, June 10. The session contained much information about the current and future role of advanced reactor technology. The session, with the subtitle “The Promise of Advanced Reactors during Uncertain Times: National Security, Jobs and Clean Energy,” featured two panels: the Lab Directors Roundtable and the Advanced Reactor Panel. The general chair is Mark Peters, Idaho National Laboratory director. The session was moderated by Corey McDaniel, of Idaho National Laboratory, and the assistant general chair of the Annual Meeting.A few of the issues covered during the dual plenary session included challenges to advanced reactor deployment, public-private partnerships in research and development, nuclear non-proliferation and security, workforce issues, and market conditions and demand.Go to ArticleTags:advanced reactorsanlans annual meetingdoegeneral chair’s special sessioninllanlornlvtrShare:LinkedInTwitterFacebook
