U.S. NRC Proposes Radiation Protection Rule Changes, Removal of ALARA Requirements Sparks Safety Controversy

The U.S. Nuclear Regulatory Commission (NRC) plans to hold an online public meeting on August 10 to discuss its proposed rule titled "Reforming and Modernizing the NRC's Radiation Protection Framework." The proposal, published on July 15, centers on reexamining the use of the linear no-threshold model in assessing radiation health effects, as well as the as low as reasonably achievable principle—the ALARA principle—derived from that model. Under the proposal, the NRC intends to remove ALARA-related requirements from its regulations and instead adopt a graded dose management framework. This framework would be based on explicit radiation protection thresholds, dose management methods, and acceptable dose measurement approaches. The regulator stated that this move is not about changing exposure standards for workers and...

Laser spectroscopy reveals for the first time the precise nuclear shape of fermium-255, offering new clues in the search for superheavy elements

An international research team has, for the first time, precisely determined the nuclear structure of the actinide fermium-255, confirming that its nucleus exhibits a pronounced prolate deformation, similar to a rugby ball. The study, published in *Physical Review Letters*, was conducted in collaboration with 18 institutions, including Johannes Gutenberg University Mainz in Germany, the Helmholtz Institute Mainz, and the University of Gothenburg in Sweden. The findings not only correct several unreasonable nuclear property values in previous standard data tables but also provide crucial experimental validation for modern nuclear theory models. Fermium is a synthetic heavy element that does not exist in nature. Fermium-255 contains 100 protons and 155 neutrons, making its experimental production extremely challenging. The research team...

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...

Russian nuclear power plants generate 129.6 billion kWh of electricity this year

Alexey Likhachev, CEO of Rosatom, recently stated that since the beginning of this year, Russian nuclear power plants have generated a cumulative total of 129.6 billion kWh of electricity, exceeding the target set by the Federal Antimonopoly Service of the Russian Federation by 7.8%. Likhachev noted that Russia is currently in its summer peak electricity consumption period, and nuclear power plants across the country are operating normally overall, with stable power generation and all safety requirements being met. He stated that hot weather does require operating entities to pay greater attention to cooling and heat reduction measures, but this is a seasonal factor that must be addressed in nuclear power plant operations. He pointed out that Russian nuclear power plants have fully considered different climatic conditions during their design and operation phases...

Construction of Proton Therapy Center in Ulsan, South Korea Faces Hurdles: Government Funding Allocation Adjustments Impact Project Progress

The proton therapy center construction project in Ulsan, South Korea, has recently encountered obstacles to progress. The project was once regarded as a key component in improving the regional cancer treatment system in southeastern South Korea, but due to shifts in government medical financial support priorities, the difficulty of securing large-scale national funding independently has increased significantly. According to information from Ulsan City on August 6, Ulsan City completed the feasibility study and basic planning services for the proton therapy center construction in March of last year and began seeking national funding. However, the Ministry of Health and Welfare responded that it would be difficult to provide large-scale project funding to Ulsan City alone. Previously, Ulsan City had planned to establish a proton therapy center to build a system enabling cancer patients to undergo surgery...

Mutsu City in Japan agrees to study receiving fuel from other companies at interim spent fuel storage facility

On August 7, Mutsu City in Aomori Prefecture, Japan, notified Tokyo Electric Power Company Holdings (TEPCO Holdings) and Japan Atomic Power Company (JAPC) that it agreed to allow the two companies to study a plan to receive spent nuclear fuel from other electric power companies at the local interim spent fuel storage facility. The facility, promoted and constructed by entities related to the two companies, is the only facility in Japan located outside nuclear power plant sites for interim storage of spent nuclear fuel. Under the current arrangement, the facility only accepts spent nuclear fuel from TEPCO Holdings and JAPC, and spent nuclear fuel from other companies is not permitted to be transported in. On the same day, Mutsu City Mayor Tomoya Yamamoto met with senior executives of the two companies at City Hall...

US Firm Standard Nuclear's Two New TRISO Fuel Plants to Enter Production by 2026, Expanding Independent US Capacity

US nuclear fuel manufacturer Standard Nuclear announced that "major construction is substantially complete" at its two TRISO fuel production facilities, SN-TN in Tennessee and SN-ID in Idaho, and that the US Department of Energy has approved the Preliminary Documented Safety Analysis (PDSA) for both plants. The two facilities share an identical design and are expected to sequentially commence commissioning and licensing before the end of 2026. Authorized under the DOE's "Fuel Line Pilot Program," each plant will initially produce up to 1 metric ton of uranium (MTU) per year of TRISO fuel, with a combined ramp-up target of 5 MTU/year in the long term, forming a tiered supply alongside the company's existing SN-0 facility (0.5 MTU/year) operating in Oak Ridge. Standard Nuclear describes itself as "the only independent TRISO fuel manufacturer in the US," having been restructured from the fuel business of Ultra Safe Nuclear following its bankruptcy in 2024 (with USNC's reactor business acquired by Nano Nuclear). Its operations cover power reactor fuel as well as space and defense radioisotope power sources. The company also participates in the DOE's Fuel Line Pilot and Surplus Plutonium Disposition programs, has been allocated HALEU by the DOE for fuel fabrication, and has established a joint-venture TRISO line at Framatome's NRC-licensed fuel facility in Richland, Washington.

South Korea advances plan to produce medical isotopes using nuclear power plants, with lutetium-177 targeted for commercial production in 2031

South Korea is advancing plans to industrialize the production of radioisotopes using nuclear power plants, with the medical isotope lutetium-177 (Lu-177) designated as the first commercial target product. Korea Hydro & Nuclear Power stated that it plans to prioritize the commercialization of Lu-177 production, with the potential to later expand the product range to include isotopes such as cobalt-60, tritium-3, and helium-3. Lu-177 is a therapeutic radioisotope widely used in the global radiopharmaceutical market, applicable in radiopharmaceuticals for diseases such as prostate cancer and neuroendocrine tumors. Previously, South Korea relied entirely on imports for its Lu-177 supply. Due to its half-life of approximately 6.6 days, the entire process from production and transportation to drug preparation and patient administration...
