Canadian laboratory validates molten salt separation process with real spent fuel, extracting nearly 90% of plutonium in 24 hours

Canadian laboratory validates molten salt separation process with real spent fuel, extracting nearly 90% of plutonium in 24 hours

A chemical experiment in Canada involving real commercial reactor spent fuel has achieved noteworthy progress. Canadian Nuclear Laboratories, in shielded hot cells at Chalk River, used irradiated spent fuel from CANDU reactors to validate the first phase of Moltex Energy's waste-to-stable-salt process. The experiment showed that within 24 hours, 89.4% of the plutonium was transferred into the molten salt; by 60 hours, this proportion rose to 94.3%. Meanwhile, the vast majority of uranium remained outside the salt phase, indicating that the process exhibits strong selectivity in separating target elements. This process, named WATSS, is not a plutonium purification route but rather a group separation technology. In addition to large quantities of uranium, spent fuel contains fission products as well as transuranic elements such as plutonium and americium, the latter being a significant source of long-term radiological risk. WATSS uses high-temperature chloride molten salt and specific reducing metals to convert transuranic oxides into salt-soluble forms, while most uranium oxides remain solid. In this experiment, researchers used niobium as the reducing metal; after 24 hours, only 0.05% of uranium entered the salt, dropping to 0.02% after 60 hours, demonstrating that it does not carry large amounts of uranium into the molten salt system.

DXA Screening Among U.S. Medicare Population Declines 35% Over Nearly Two Decades

DXA Screening Among U.S. Medicare Population Declines 35% Over Nearly Two Decades

A new study shows that between 2005 and 2023, the rate of dual-energy X-ray absorptiometry (DXA) examinations among U.S. Medicare beneficiaries declined significantly, by 35%. DXA is commonly used for bone density testing and osteoporosis-related screening, and the findings suggest that disparities in screening access across different populations are widening. Researchers analyzed claims data from more than 5 million Medicare beneficiaries. The results showed that DXA utilization fell from 7,255 exams per 100,000 beneficiaries in 2005 to 4,690 per 100,000 beneficiaries in 2023. The study was published in Osteoporosis International. The decline was not uniform across populations...
