Nuclear thermal propulsion (NTP) is one technology that could propel a spacecraft to Mars and back, using thermal energy from a reactor to heat an onboard hydrogen propellant. While NTP is not a new concept, fuels and reactor concepts that can withstand the extremely high temperatures and corrosive conditions experienced in the engine during spaceflight are being designed now.

BWX Technologies announced on December 13 that it has delivered coated reactor fuels to NASA for testing in support of the Space Technology Mission Directorate’s NTP project. BWXT is developing two fuel forms that could support a reactor ground demonstration by the late 2020s, as well as a third, more advanced and energy-dense fuel for potential future evaluation. BWXT has produced a videoof workers processing fuel kernels in a glovebox.

First-of-a-kind research reactors, demo reactors, and research facilities are being developed and sited on university campuses to support the broader deployment of advanced reactors. At the 2021 ANS Winter Meeting and Technology Expo, during a December 2 panel session titled “Research Reactors in Support of Advanced Reactor R&D,” several of these planned projects were discussed in detail—including a molten salt reactor in Texas and a high-temperature gas–cooled reactor in Illinois.

The session was sponsored by the Reactor Physics Division and organized and chaired by Pavel Tsvetkov, of Texas A&M University. A video of the session is available to registered Winter Meeting attendees.

Texas A&M to lead isotope R&D traineeship program

December 9, 2021, 9:31AMNuclear News

The Department of Energy is dedicating $2 million to the establishment of a first-of-its-kind program to train undergraduate and graduate students in isotope research and development, production, and processing. Texas A&M University will serve as the Isotope Traineeship Coordination (ITC) site, collaborating with a team of 14 colleges and universities and three national laboratories: Argonne National Laboratory, Lawrence Livermore National Laboratory, and Los Alamos National Laboratory.

Hydrogen: The best shot for nuclear sustainability?

December 3, 2021, 3:00PMNuclear NewsSusan Gallier

Nuclear power plants are not quick to change. So when four utilities announce they will make room for shiny new electrolyzers and consider tweaking their business model, that’s news.

Nuclear power plants can leverage the energy stored in some of the world’s heaviest elements to generate the lightest: hydrogen. That is not news, but it casts an aura of alchemy over straightforward engineering. Amid the hype, and the hope of significant federal funding, it’s worth acknowledging that hydrogen has an industrial history over 100 years old. In the potential matchup of hydrogen and nuclear power, it’s nuclear that would be the newcomer.

The newest generation of lithium-ion batteries now being developed uses thin-film, solid-state technology and could soon safely power cell phones, electric vehicles, laptops, and other devices. However, like all batteries, solid-state lithium-ion batteries have a drawback: Impedance—electrical resistance—can build up as batteries are discharged and recharged, limiting the flow of electric current.

During the EnRicH 2021 European Robotics Hackathon, Southwest Research Institute’s unmanned aircraft system (UAS or drone) explored and mapped the interior of a nuclear power plant, detecting radiation sources autonomously, without the aid of a human pilot.

SwRI’s UAS technology can potentially assist in life-saving search-and-rescue missions and hazardous inspections at industrial facilities and infrastructure following natural disasters and other incidents.

NASA and Idaho National Laboratory have just opened a competitive solicitation for U.S. nuclear and space industry leaders to develop innovative technologies for a fission surface power system that could be deployed on the surface of the moon by the end of the decade. Battelle Energy Alliance, the managing and operating contractor for INL, issued a request for proposals and announced the news on November 19. Proposals are due February 17.

Southern Company and the Department of Energy have announced an agreement to demonstrate the world’s first fast-spectrum salt reactor in collaboration with TerraPower and a host of other participants at Idaho National Laboratory. With this announcement, at least four of the DOE’s Advanced Reactor Demonstration Project awardees featuring four different coolants—helium (X-energy), sodium (TerraPower), fluoride salt (Kairos Power), and chloride salt (Southern, with TerraPower)—have announced a site and a commitment to build either a full-size demo reactor or a scaled-down experimental reactor.

Swapping conventional electromagnetic radiation for fast neutrons, a team of research engineers at Lancaster University in the United Kingdom, working with the Jozef Stefan Institute of Slovenia, report that they have successfully transmitted digital information wirelessly using nuclear radiation. The researchers’ attempts to transmit words and numbers using standard ASCII code “were 100 percent successful,” according to a November 10 press release from Lancaster University. Their research will be published in an upcoming issue of Nuclear Instruments and Methods in Physics Research and is now available online.

Diablo Canyon report takeaways: California has options, and it’s time for debate

November 10, 2021, 12:02PMNuclear News

A new study by researchers from Stanford University and the Massachusetts Institute of Technology—An Assessment of the Diablo Canyon Nuclear Plant for Zero-Carbon Electricity, Desalination, and Hydrogen Production—makes a compelling case that the 2018 decision to shut down California’s only operating nuclear power plants needs another look—and that revenue options could make reversing the decision not just feasible but economically attractive.

“Fast-forward three years and things have changed,” said Jacopo Buongiorno, a professor of nuclear science and engineering at MIT and one of the authors of the report, during a November 8 webinar. Since the decision was made to shut down Diablo Canyon’s twin pressurized water reactors in 2024 and 2025 when their current licenses expire, the state has passed bills calling for net zero carbon emissions by 2045 and for restrictions on land use that could effectively limit solar installation sprawl. Californian’s have also experienced repeated grid reliability issues and prolonged drought conditions.

Lackey

Two student interns at Pacific Northwest National Laboratory looking for an easier way to monitor the acidity and phosphate concentrations of a process fluid like dissolved nuclear fuel have published research on a monitoring method that provides real-time data without the need for physical sampling of the substance. Their story was published on October 27 on PNNL’s website.

Student leaders: Hope Lackey conducted pH measurement and chemical analysis research during her Science Undergraduate Laboratory Internships (SULI) experience at PNNL in 2018 while she was working toward her undergraduate degree in environmental studies at the College of Idaho. Andrew Clifford, also a SULI intern and a student at the College of Idaho, partnered with Lackey between his junior and senior year, while studying for a dual bachelor’s in chemistry and math/physics.

Germany could save 1 billion tons of CO2 by 2045, says study

October 26, 2021, 9:31AMNuclear News

“The price of anti-nuclear psychosis (for that is what it is) will be paid by vulnerable countries and future generations who suffer the escalating damages of climate breakdown,” writes environmentalist and author Mark Lynas in the foreword to a new study, One Billion Tons: CO2 Reductions and a Faster Coal Exit in Germany. “This report puts numbers on this price to be paid for the first time—a nice round number of a billion tons.”

According to Lynas, the billion tons is the “opportunity cost” of the German government’s plan to shutter its remaining nuclear power plants by 2022 while keeping its coal plants going until 2038. (Three of those plants, Brokdorf, Grohnde, and Gundremmingen, are scheduled to close later this year.)
