Brian Wirth, UT-ORNL Governor’s Chair Professor, was elected Fellow of the American Physical Society for his groundbreaking work on plasma-surface interactions. His research has led to high-fidelity simulation tools predicting fusion plasma surface interactions, resulting in significant advancements.
A novel observation of enhanced neutron-rich particle emission from out-of-fission-plane has been made in Fermi energy heavy ion reactions. This study uses advanced detection system CSHINE to measure charged particles and fission fragments, providing a vivid view of isospin migration dynamics.
Researchers developed a detector that senses and analyzes antineutrinos emitted by nuclear reactors, enabling detection of reactor use even from hundreds of miles away. The device exploits Cherenkov radiation to characterize energy profiles and can distinguish between operational cycles and specific isotopes in spent fuel.
A team from Tokyo Institute of Technology has developed a method to remotely monitor nuclear reactors using antineutrinos. The approach, published in the Journal of Nuclear Science and Technology, could help prevent the manufacturing of materials for nuclear weapons.
Researchers found a correlation between light precision metals like silver and rare earth nuclei like europium, indicating a consistent process operating during heavy element formation. The pattern provides a clear signature of fission creating these elements.
Researchers from Oak Ridge National Laboratory have validated the first technique to visualize and monitor molten salt penetration depth and distribution in graphite's pores. They identified graphite microstructure as the most important factor in determining molten salt penetration and density distribution for a given temperature and p...
Researchers developed a method to scale up nanocages to trap noble gases like krypton and xenon. The team used commercial materials and found the optimal temperature range for trapping gas atoms inside the cages.
Researchers use radiochronometry and forensic methods to determine the age and origins of Heisenberg and Diebner cubes. The findings will help train international border guards and nuclear forensics researchers to detect nuclear material.
A series of experiments at the ALTO particle accelerator facility revealed that fragments resulting from nuclear fission obtain intrinsic angular momentum after fission, not before. The study analyzed gamma rays emitted in the process and found a saw-tooth dependence of spin on fragment mass.
Nuclear fission reactors are being considered as top candidates to generate electricity in space due to their reliability and capacity. The technology has been tested and could provide a power source for several years, making it an attractive option for lunar and Martian settlements.
Simulations of nuclear fission using quantum-mechanics show that pear-shaped deformation is favored by strong Coulomb repulsion in fragments. This mechanism explains asymmetric fission in several systems and improves predictions for exotic nuclei.
Researchers at Tokyo Tech have developed a new Langevin model that predicts low-energy fission more accurately by accounting for the deformation of nuclear fragments. The four-dimensional model fits empirical data better than previous models and has potential applications in radioactive waste containment and nuclear power generation.
