Kazakh scholars call for integrated radioecological monitoring system in border regions amid Central Asian nuclear power development

Kazakh scholars call for integrated radioecological monitoring system in border regions amid Central Asian nuclear power development

As energy demand continues to grow in Central Asian countries, nuclear power is becoming an important direction in regional energy policy. Kazakhstan has decided to build its own nuclear power plant, while neighboring countries such as Uzbekistan are also advancing or preparing similar projects. Nuclear energy is regarded as a key option for ensuring electricity supply and reducing greenhouse gas emissions, but its development cannot be limited to the construction of power plants alone. It must be accompanied by a comprehensive ecological and radiation safety assurance system, particularly in areas where cross-border impacts may exist. Although modern nuclear power plants are designed in accordance with strict international safety standards, environmental monitoring cannot be predicated on the probability of accidents. The impact of large industrial facilities on the surrounding environment requires...

South Korea to Resume Actinium-225 Production Next Year to Ease Shortage of Raw Materials for Anti-Cancer Radiopharmaceuticals

South Korea to Resume Actinium-225 Production Next Year to Ease Shortage of Raw Materials for Anti-Cancer Radiopharmaceuticals

South Korea's domestic production project for actinium-225 (Ac-225), a radioisotope used in next-generation cancer treatment, is expected to resume next year after being stalled for more than a year. Funding was secured in the first half of this year, and the Korea Institute of Radiological & Medical Sciences (KIRAMS) plans to complete facility construction and trial production before launching full-scale production in the second half of next year, aiming to alleviate the raw material shortage facing domestic clinical research and radiopharmaceutical development. KIRAMS is affiliated with the Ministry of Science and ICT. The institute received approval from the Nuclear Safety and Security Commission in May last year to produce Ac-225 using a cyclotron. The project first entered the review process in 2018 and took seven years to gain approval, with initial production originally planned by the end of last year. However, work on upgrading production facilities and procuring equipment was suspended after approximately 2 billion KRW in budget was not approved during parliamentary review.

CMS records highest-energy lepton pairs to date, testing the possibility of a composite Higgs boson

CMS records highest-energy lepton pairs to date, testing the possibility of a composite Higgs boson

The CMS experiment recently used the complete proton-proton collision dataset collected during Run 2 of the Large Hadron Collider and the first two years of Run 3, namely 2022 to 2023, to search for clues that the Higgs boson may be composed of smaller constituents. The analysis results show that the experimental data are consistent with Standard Model predictions, with no evidence pointing to new physics yet. Whether the Higgs boson is an elementary particle or a composite particle with deeper structure is a long-standing question in particle physics. To test this possibility, the CMS team adopted two complementary approaches: on one hand, directly searching for new heavy particles that could be produced at the Large Hadron Collider; on the other hand, indirectly probing the effects of new particles with higher masses that are difficult to produce directly through subtle deviations in high-energy electron pair and muon pair production processes.

LLNL Research in the U.S. Reveals New Mechanisms of Laser Polarization Effects in NIF Inertial Confinement Fusion Experiments

LLNL Research in the U.S. Reveals New Mechanisms of Laser Polarization Effects in NIF Inertial Confinement Fusion Experiments

Researchers at Lawrence Livermore National Laboratory (LLNL) have recently discovered in studies related to the National Ignition Facility (NIF) that the polarization state of lasers may influence the cross-beam energy transfer (CBET) process in inertial confinement fusion experiments and could help reduce backscatter and the risk of damage to optical components. The related paper, titled "Effects of Laser Polarization on Cross-Beam Energy Transfer in Inertial Confinement Fusion," was recently published as a featured article in the journal Physics of Plasmas. NIF experiments demand extremely high precision in laser control. The facility's 192 laser beams must be focused to a width of a few millimeters and enter the target area through holes approximately 3 millimeters in diameter located at the top or bottom of a gold hohlraum. The hohlraum is about 2 centimeters in diameter. After the lasers enter the plasma, different beams cross each other and undergo energy transfer, a process known as cross-beam energy transfer. When designing NIF inertial confinement fusion experiments, scientists carefully tune the laser wavelengths to use CBET to balance energy distribution and improve implosion symmetry.

After only 4 days of restart, Unit 2 of France's Golfech Nuclear Power Plant shut down again due to Garonne River water temperature approaching limit

After only 4 days of restart, Unit 2 of France's Golfech Nuclear Power Plant shut down again due to Garonne River water temperature approaching limit

On the evening of August 8, French utility EDF (Électricité de France) once again shut down Unit 2 of the Golfech Nuclear Power Plant, just four days after the unit had been restarted. The direct cause of this shutdown was that the water temperature of the Garonne River was expected to reach 28°C on August 9, hitting the local operational limit. Since Unit 1 had already been taken offline for maintenance and fuel replacement, the closure of Unit 2 left both reactors at the Golfech plant simultaneously out of service, with the station temporarily ceasing power generation. Located in the Tarn-et-Garonne department of France, the Golfech Nuclear Power Plant was commissioned between 1991 and 1994, and features two 1,300 MW pressurized water reactor units. It draws cooling water from the Garonne River and dissipates heat through natural-draft cooling towers. According to EDF dat...

CMS completes high-pileup collision test, validating particle reconstruction algorithms for High-Luminosity LHC operation

CMS completes high-pileup collision test, validating particle reconstruction algorithms for High-Luminosity LHC operation

In 2025, the Large Hadron Collider (LHC) conducted a dedicated test over several days to simulate high-intensity collision conditions closer to those expected during future operation of the High-Luminosity Large Hadron Collider (HL-LHC). The Compact Muon Solenoid (CMS) experiment team used this opportunity to test whether existing particle tracking, identification, and reconstruction software, along with a new class of machine learning methods, can adapt to the more complex collision conditions of the HL-LHC era. During LHC operation, each crossing of proton beams produces multiple proton–proton collisions simultaneously, a phenomenon known as pileup. The current Run 3 features approximately 65 simultaneous interactions, while the HL-LHC is expected to reach 140 to 200. To...
