Connecting nuclear engineers and scientists with space exploration missions has been a focus of the American Nuclear Society’s Aerospace Nuclear Science and Technology Division since its creation in 2008. One of the main ways those connections are made is through the Nuclear and Emerging Technologies for Space (NETS) conference, which the division supports in conjunction with the National Aeronautics and Space Administration.

Purdue University mass-alpha spectroscopy research draws notice

April 14, 2022, 12:00PMNuclear News

Research into the high-resolution detection of plutonium mixtures by Purdue University professor Rusi Taleyarkhan and his team was featured on the cover of the February issue of the Journal of Analytical Atomic Spectroscopy, published by the British Royal Society of Chemistry.

The published research focuses on novel hybrid mass-alpha spectroscopy technology. Taleyarkhan and his team applied centrifugally tensioned metastable fluid detector sensor technology to the detection of mixtures of plutonium-239/240. This technology can serve as an alternative to conventional alpha radiation spectroscopy sensors and to mass spectroscopy systems, which can take weeks to deploy and are cost-prohibitive, especially when deployed in low-radiation fields for long periods of time.

DOE says sale of HALEU will not adversely affect uranium industry

April 12, 2022, 3:02PMNuclear News

The Department of Energy has determined that the sale, lease, or transfer of up to 750 kilograms of high-assay low-enriched uranium (HALEU) per calendar year to support the production of molybdenum-99 will not have an adverse material impact on the domestic uranium mining, conversion, or enrichment industry.

Schönfeldt

In a recent episode of Azeem Azhar’s Exponential View, Troels Schönfeldt, chief executive officer of Seaborg Technologies, discussed his company’s reactor technology and other nuclear-related issues. Seaborg Technologies, which was founded in Copenhagen, Denmark, in 2014, is developing a compact molten salt reactor (CMSR) that it says is safe, significantly smaller, better for the environment, and inexpensive, even compared to fossil fuels, and can be manufactured quickly and deployed on barges to any location worldwide. The Exponential View is a podcast presented by the Harvard Business Review and hosted by Azhar, an entrepreneur and investor.

Different type of reactor: “We’re designing a fundamentally different type of nuclear reactor,” Schönfeldt said. “The powerful bullet points [are] that it cannot melt down or explode, it cannot release gases, it cannot be used for nuclear weapons. It could even burn nuclear waste, so we can get rid of some of the old waste stockpiles.”

We cannot eliminate our way to net zero,” said Sen. Joe Manchin (D., W.Va.) during a visit to the ITER site in Cadarache, France, on March 25. “We have to innovate, not eliminate, our way to carbon neutrality."

Manchin was joined by Ali Nouri, assistant secretary for congressional and intergovernmental affairs at the Department of Energy; Kathy McCarthy, director of the U.S. ITER Project Office; and other U.S. officials for a tour of the ITER Assembly Hall led by ITER chief scientist Tim Luce, head of the ITER Science and Operations Domain. The visit was described in an ITER Newsline article published on March 28.

The White House Office of Science and Technology Policy and the Department of Energy cohosted the White House Summit on Developing a Bold Decadal Vision for Commercial Fusion Energy on March 17. The livestreamed event brought together fusion leaders from government, industry, academia, and other stakeholder groups to showcase recent achievements in fusion research and discuss the administration’s strategy to support the development of commercial fusion energy. Energy Secretary Jennifer Granholm’s announcement of a new agency-wide fusion energy initiative and a funding opportunity worth $50 million for magnetic confinement fusion research made March 17 a lucky day indeed for the U.S. fusion energy community.

NRC probe of NIST reactor fuel failure finds apparent violations

In the 13 months since a fuel element failure triggered a scram of the research reactor at the National Institute of Standards and Technology’s NIST Center for Neutron Research (NCNR), the event and its causes have been scrutinized by both NIST and the Nuclear Regulatory Commission.

Initial conclusions from an NRC special inspection released on March 16 confirm that while public health and safety was maintained during and after the event, and doses to reactor facility staff were well below regulatory limits, a safety limit was violated when the temperature of the fuel cladding of a single fuel element in the 20-MWt research reactor reached a temperature high enough to partially melt the element.

DOE funds R&D for advanced reactor fuel cycle management

March 14, 2022, 7:01AMNuclear News

The Department of Energy's Advanced Research Projects Agency–Energy (ARPA-E) has awarded a total of $36 million for 11 projects to develop technologies that will limit the amount of waste produced from advanced reactors and will support sustainable domestic fuel stocks. The projects include research into the facilities and systems required to reprocess, recycle, and dispose of spent fuel generated through diverse advanced reactor fuel cycles.

With three commercial teams under contract to produce reactor designs for nuclear thermal propulsion rockets that would use solid high-assay low-enriched uranium fuel to heat hydrogen propellant, NASA’s investment in nuclear thermal propulsion (NTP) has increased in recent years. But just as there is more than one way to fuel a terrestrial reactor, other fuels are under consideration for future NTP rocket engines.

Constellation Energy’s Dresden nuclear power plant in Illinois is helping University of Chicago researchers to detect neutrinos in an effort to advance knowledge of the fundamental laws governing particle and nuclear interactions. The researchers are taking advantage of the large number of neutrinos generated by Dresden’s boiling water reactors to conduct experiments, using what UChicago calls the world’s smallest neutrino detector to track and record the ghostlike particles.

Researchers advancing particle accelerator technology for medical, security, energy, and industrial applications have a new funding opportunity announced on February 16 by the Department of Energy’s Office of Science (DOE-SC). The funding will support research to advance particle accelerator technology for medical, security, energy, and industrial applications. Grants will be awarded for work focused on innovation, technology transfer, and supply chain resiliency that falls under one of two DOE-SC programs: the Accelerator Stewardship program, which supports cross-disciplinary teams to solve high-impact problems, and the Accelerator Development program, which is aimed at strengthening domestic suppliers of accelerator technology.

Powering our nuclear fleet with artificial intelligence

February 18, 2022, 2:55PMNuclear NewsJ. Thomas Gruenwald, Jonathan Nistor, and James Tusar

We’ve all heard the stories of lost treasures being found in dust-­filled attics, locked away in forgotten wall safes, or hidden in secret compartments of antique desks. Some of these true accounts, such as a rare copy of the Declaration of Independence hidden behind wallpaper or an authentic Van Gogh relegated to collecting dust in an attic, can lead to seven-­ and eight-­figure jackpots when the discoveries are made.

What about our own treasures locked away in long-­forgotten data storage drives or plant process computers? Imagine that you could gain keen insight into every operational issue you have by using the data you’ve been collecting for decades. In a nuclear power plant, data is routinely generated and collected for a myriad of purposes—whether it be for core monitoring, exposure accounting, equipment monitoring, or other reasons. While that data may serve its primary function exceedingly well, the information contained within it and in the aggregate is profoundly richer than most could imagine.
