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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

Effects of beam convergence on fusion reaction rate in the cylindrical IECF device are investigated using 2-D simulation code by changing electrode shape. Simple simulation well reproduces experimentally obtained dependences of neutron production rate vs. discharge voltage and current, and it is found that almost all reactions occur by beam-background gases collisions, not beam-beam collisions. Results show that fusion reaction rate increases significantly with increase of beam convergence, therefore, increase of ion densities in the center, even in the devices where beam-background gas collision is dominate.
