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

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.

Russian Company InterPolaris Completes Testing of Heat Exchangers and Mechanical Filters for Nuclear-Powered Icebreakers

Russian company InterPolaris has achieved a significant milestone in the manufacturing project of equipment for nuclear-powered icebreakers, successfully completing tests on two shell-and-tube heat exchangers and two mechanical filters. These units are designed for the specific operating environment of nuclear-powered icebreakers, and passing the tests means the products meet design requirements in terms of strength, sealing, stability, and long-term service capability. The shell-and-tube heat exchangers that passed verification are primarily used to heat water containing decontamination solutions using heating steam. Although this is a common heat exchange process in principle, in the icebreaker application scenario, the equipment must meet requirements far exceeding ordinary industrial standards. This horizontally arranged equipment is designed with consideration for continuous operation under prolonged ship listing conditions, with fixed structures capable of withstanding loads from various directions, and is required to maintain stable parameters and reliable sealing under complex sea conditions and operating regimes.

Indian Parliamentary Committee Emphasizes Urgency of Accelerating Uranium Mining Projects

On August 7, 2026, the Indian Parliamentary Committee on Public Undertakings noted in its report on nuclear power expansion progress that India's uranium mining project expansion needs to be accelerated. DAE has committed UCIL to doubling production by 2036 through enhancing existing capacity and new projects in Jharkhand, Rajasthan, and Chhattisgarh, but the committee considers this timeline too late—NPCIL's installed capacity will surge significantly over the next decade, and delays in mining clusters would prolong the strategic vulnerability period of imported fuel. Currently, PHWR units of approximately 25 GWe require about 5,400 tonnes of U3O8 annually, with UCIL able to meet only about 30% of that demand; accelerated domestic production and diversified supply are needed to reduce import dependence. The committee supports UCIL forming a joint venture with NTPC to acquire equity stakes in overseas uranium assets...

Cancer Cryoablation Treatments at Southeast Region Nuclear Medicine Center in Korea Exceed 100 Cases

The Southeast Region Nuclear Medicine Center announced on August 8 that since introducing cancer cryoablation in 2024, the center has completed over 100 related procedures, providing treatment to a total of 104 cancer patients. Cryoablation is a minimally invasive tumor treatment method. During the procedure, doctors insert a thin treatment needle precisely into the tumor site under CT or ultrasound imaging guidance, freezing the lesion at ultra-low temperatures of minus 40 degrees Celsius or lower to cause cancer cell necrosis. As the low-temperature freezing itself has a certain anesthetic effect, this technique helps reduce patient pain, minimize damage to surrounding normal tissues, and promote faster postoperative recovery. According to the center, among the patients treated so far, there are 58 cases of liver cancer and liver metastases, 17 cases of primary lung cancer, recurrent lung cancer, and lung metastases, and 29 cases of renal cancer. Among them, 8 patients underwent treatment for two lesions simultaneously in a single procedure. Liver...
