Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have developed a new model of how heat flows within plasmas. According to PPPL, the model could improve insights into the behavior of plasmas and may help engineers avoid the conditions that could lead to heat loss in future fusion facilities.

The Department of Energy is providing $50 million in a cost-sharing project with Exelon Generation to digitalize the control room at the company’s Limerick nuclear power plant, the department announced yesterday. Once implemented, the facility will house the first fully digital safety system upgrade at a U.S. nuclear power plant.

The Department of Energy’s Office of Environmental Management (EM) has released an animated video of the Direct-Feed Low-Activity Waste (DFLAW) Program at the Hanford Site near Richland, Wash. The video shows the integrated procedure for treating Hanford’s radioactive tank waste, a process EM says is a key component of its strategic cleanup vision.

The Department of Energy’s National Nuclear Security Administration has issued a cooperative agreement worth $35 million to SHINE Technologies, based in Janesville, Wis., to support the commercial production of molybdenum-99, a critical isotope used in more than 40,000 medical procedures in the United States each day, including the diagnosis of heart disease and cancer.

International nuclear safeguards verification relies on a precise count of isotope particles collected on swipes during International Atomic Energy Agency inspections of nuclear facilities and isolated through a series of lengthy chemical separations that can take about 30 days to complete. On October 15, Oak Ridge National Laboratory—a member of the IAEA’s Network of Analytical Laboratories (NWAL)—announced that analytical chemists at the site have developed a faster way to measure isotopic ratios of uranium and plutonium collected on swipes, which could help IAEA analysts detect the presence of undeclared nuclear activities or material.

In an open letter published last week in Welt, 25 leading German and foreign academics, environmentalists, and journalists attempt to convince the German people that continuing with their nation’s phase-out of nuclear power is not a good idea, and certainly not a green one.

ARTMS, a Canadian producer of medical isotopes, announced that it has registered the cyclotron production of gallium-68 with the government of Canada, filing a Type 1 Master File with the Health Products & Food Branch of Health Canada. The Ga-68 radioisotope is used in nuclear medicine diagnostic procedures utilizing positron emission tomography (PET) imaging.

The International Energy Agency released its flagship report, World Energy Outlook 2021, on October 13, “at a time when policymakers are contending with the impacts of both climate change and volatile energy markets” and ahead of the COP26 Climate Change Conference in Glasgow, which begins October 31. With a net-zero emissions by 2050 (NZE) scenario that calls for nuclear power capacity to almost double by 2050, the report acknowledges that rapid development of advanced nuclear technologies could expand opportunities for nuclear energy to provide low-carbon electricity, heat, and hydrogen.

The nuclear industry has historically relied on intermittent ultrasonic test and visual inspections of pressurized water reactor components to identify and manage degradation. While this reactive approach has proven to be effective, imagine a scenario in which the degradation could propagate throughout the reactor internals, making a more proactive measure necessary to avoid a major enterprise risk to the plant. Could a utility identify the onset of degradation within the reactor internals during plant operation? If so, could a repair be developed prior to the next refueling outage to prevent additional, cascading degradation? That is exactly the situation that Public Service Enterprise Group (PSEG) and Westinghouse engineers were able to navigate over the course of the 2019–2020 operating cycle at Salem Unit 1, resulting in a tremendous success for the plant and a historic landmark in the nuclear industry, while earning the team a 2021 Nuclear Energy Institute Top Innovative Practice (TIP) award.
