ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

Reduction of the loss regions existing in the velocity space plays an important role in improvement of the confinement in the tandem mirror. Particle flow into the loss region affects the axial confinement. The ions being trapped in the magnetic mirror field are scattered from the trapped region into the loss region through the loss boundaries. In order to investigate the fine structure appeared in the loss region, the end-loss energy component analyzer (ELECA) devices have been constructed and located on both sides of the tandem mirror. Three kinds of structures in the loss region were observed in the RF-driven tandem mirror plasma.
