Romania's Cernavoda Nuclear Power Plant to Remain Offline Until at Least September 18 Due to Low Danube River Levels

On September 8, Romania's Cernavoda Nuclear Power Plant was expected to remain offline until at least September 18 due to low water levels in the Danube River. Emil Macovei, Technical Director of Nuclearelectrica, the operator of the Cernavoda plant, stated that over the next 10 days, the Danube's water volume would still be insufficient to support the restart of either of the plant's two units. Romania's Antena 3 television channel quoted him as saying that current hydrological conditions do not yet meet the requirements for unit operation. Cristian Busoi, Secretary of State at Romania's Ministry of Energy, said that predictions regarding the plant's restart timeline were "rather optimistic," and the ministry is currently unable to provide a definitive date for resuming operations. He confirmed that...

CERN Large Hadron Collider Data Challenge Models of Oxygen and Neon Nucleus Structure

Physicists at the European Organization for Nuclear Research (CERN), analyzing a new batch of collision data from the CMS detector at the Large Hadron Collider, have found that oxygen and neon nuclei do not behave entirely as predicted by existing models in high-energy collisions. This result indicates that the scientific community's understanding of the shapes and internal structures of certain light nuclei still requires further refinement. In high-energy nuclear collisions, a quark-gluon plasma is briefly formed in the collision region. This state of matter decays rapidly, but the collective flow characteristics of its particles can be used to infer the collision geometry and indirectly provide information about nuclear structure. Researchers believe that symmetric collisions of light ions help better control the initial collision conditions, making them suitable for studying collective responses in small systems.

CERN measures niobium-94 neutron capture for the first time, shedding new light on the mystery of molybdenum abundance in ancient stardust

The n_TOF collaboration at CERN recently reported that researchers have for the first time measured the probability of neutron capture by niobium-94. The results, published in Physical Review Letters, provide new experimental evidence for explaining the anomalous abundance of molybdenum-94 in presolar grains. The EAR2 facility in the n_TOF experiment at CERN produces intense neutron beams, opening new possibilities for nuclear research. Credit: CERN Niobium-94 is a niobium isotope containing 41 protons and 53 neutrons, occupying a critical juncture in the nuclear reaction chain that produces heavy elements in dying stars. Researchers are interested in it because niobium-94 is very close to molybdenum-94, differing by just one fewer proton and one more neutron. Under the high-temperature, high-pressure conditions inside stars, niobium-94 may either transform into molybdenum-94 through beta decay or form niobium-95 through neutron capture. The competition between these two reaction pathways directly affects scientists' understanding of the origin of molybdenum-94.
