U.S. to Resume Shipping Transuranic Waste Drums from Savannah River Site to WIPP for Permanent Disposal

The U.S. Department of Energy Office of Environmental Management (EM) will resume shipping remote-handled transuranic waste drums from the Savannah River Site (SRS) in South Carolina to the Waste Isolation Pilot Plant (WIPP) in New Mexico for permanent disposal on July 28, 2026. Prior to resuming shipments, relevant teams have completed flammable gas analysis, confirming that these waste containers meet safety requirements for transport to the underground disposal facility. Flammable gas sampling is a critical safety step before transuranic waste transportation. Workers assess potential combustion risks inside containers by detecting gases such as hydrogen, methane, and volatile organic compounds, and confirm their safety during transport and disposal...

U.S. Nuclear Regulatory Commission Signs Memorandums of Understanding with Coast Guard and Marine Minerals Administration to Strengthen Offshore Nuclear Energy Cooperation

Recently, the U.S. Nuclear Regulatory Commission (NRC) signed Memorandums of Understanding (MOUs) with the U.S. Coast Guard (USCG) and the newly established Marine Minerals Administration (MMA), respectively, aimed at strengthening coordination and cooperation on civilian offshore nuclear projects. These initiatives come at a time of growing interest in nuclear technology within the commercial shipping sector, including projects such as nuclear-powered vessels and floating nuclear power plants. The agreement with the Coast Guard updates a previous agreement signed with the Atomic Energy Commission in 1973, aiming to modernize regulatory processes and ensure effective management of the design, construction, operation, and oversight of civilian nuclear reactors at sea. Meanwhile, the NRC's cooperation with the MMA focuses on clarifying jurisdictional issues for any potential nuclear projects on the U.S. Outer Continental Shelf (OCS).

U.S. Team Traces Source of Anomalous Gamma Rays from Zinc-70, Nuclear Magnetic Transitions May Improve Models of Heavy Element Formation

An international research team led by scientists from the Facility for Rare Isotope Beams (FRIB) at Michigan State University has recently identified the source of the large number of low-energy gamma rays emitted by zinc-70 nuclei. The study suggests that magnetic transitions occurring within the nucleus are the key reason for this anomalous signal enhancement. The findings were published in the journal Nature under the title "Magnetic character of the low-energy enhancement in 70Zn." Gamma rays are electromagnetic radiation released when excited atomic nuclei transition to lower, more stable energy levels. For a long time, scientists have observed an anomalous increase in the number of low-energy gamma rays in some atomic nuclei, known as the low-energy enhancement (LEE), but its physical mechanism had remained unclear...

LHAASO "Sees" for the First Time How Black Holes Produce the Highest-Energy Particles in the Universe

How do black holes accelerate particles to the highest energies in the universe? The latest research provides the answer. On July 31, it was learned from the Institute of High Energy Physics of the Chinese Academy of Sciences that the Large High Altitude Air Shower Observatory (LHAASO, "Lasso"), a major national scientific and technological infrastructure, has for the first time clearly observed the process by which a black hole, while devouring material from its companion star, regularly produces the highest-energy particles in the universe like a metronome, and has identified the first PeV gamma-ray variable source. The related research results were published in the *National Science Review*. Cygnus X-3 is a binary system located in the constellation Cygnus, consisting of a black hole and a massive companion star. The gravitational pull there is extremely strong, and the black hole frantically accretes the stellar wind blown off by its companion. LHAASO detected...
