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.
Fuel Cycle & Waste Management
Devoted to all aspects of the nuclear fuel cycle including waste management, worldwide. Division specific areas of interest and involvement include uranium conversion and enrichment; fuel fabrication, management (in-core and ex-core) and recycle; transportation; safeguards; high-level, low-level and mixed waste management and disposal; public policy and program management; decontamination and decommissioning environmental restoration; and excess weapons materials disposition.

ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

The development of fusion energy will require materials resilient to harsh bombardment by energetic neutrons and plasma. The Gas Dynamic Trap (GDT) concept in Novosibirsk is proposed as a neutron and plasma source to test and validate appropriate materials. Recent results showed plasma beta of 0.6, provide a solid basis for extrapolating to a fusion relevant neutron source. Relative to previous magnetic mirror neutron sources, the GDT concept operates with simpler axisymmetric magnets and at higher efficiency. Plasma in the GDT device operating at the present time in the Budker Institute includes two ion components: 250 eV maxwellian warm ions and anisotropic hot ion population produced by 25 keV 5 MW oblique neutral beam injection.
