BESSY II reveals early-stage copper oxidation: providing evidence for catalyst development and corrosion research on nuclear waste final disposal containers

Germany's BESSY II synchrotron facility has recently provided new experimental insights into the early-stage oxidation process of copper surfaces. The study shows that before the formation of pure copper oxides, copper and oxygen atoms first form complex surface superstructures, such as "29"CuₓO. The chemical state of such structures has long been debated, and the findings are of reference value for catalyst research as well as for corrosion protection studies of copper containers used for radioactive waste final disposal. Before the formation of pure copper oxide, complex superstructures composed of copper and oxygen atoms emerge—such as "29"CuxO. HZB In everyday environments, copper surfaces gradually lose their red metallic luster and form a greenish oxide layer. This layer structure can slow further corrosion over an extended period. Regarding the initial stages of this process, the core question researchers focus on is: to what extent are copper atoms actually oxidized once oxygen enters the copper surface. Since conventional spectroscopic methods struggle to clearly distinguish between pure copper and partially oxidized surfaces, such oxidation states have previously been difficult to determine directly.

Paraguay's Nuclear Power Generation Debate Heats Up: Regulator Supports Private Sector Participation

Paraguay's Radiation and Nuclear Regulatory Authority (ARRN) has welcomed the open attitude shown by the National Electricity Administration (ANDE), stating that allowing or encouraging private sector participation in nuclear power generation projects would bring new discussion space to the country's energy mix. This stance indicates that nuclear energy is no longer just a long-term technical vision but has begun to enter the public agenda of policy, investment, and regulatory coordination. Paraguay has long relied on hydropower resources, with major projects such as Itaipu and Yacyretá giving it an advantage in clean electricity. However, with domestic industrialization, growing electricity consumption, and changes in the regional energy market, sole reliance on hydropower also faces pressures from seasonality, hydrological conditions, and long-term demand...

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.
