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.
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.

Standard on fixed neutron absorbers in nuclear facilities outside reactors just issued (ANS-8.21)
ANSI/ANS-8.21-2023, Use of Fixed Neutron Absorbers in Nuclear Facilities Outside Reactors, has just been issued by the American Nuclear Society Standards Committee. The standard was approved by the American National Standards Institute (ANSI) on June 20, 2023, as a revision and consolidation of ANS-8.21-1995 (R2019) (withdrawn) (same title) and ANS-8.5-1996 (R2022) (withdrawn), Use of Borosilicate-Glass Raschig Rings as a Neutron Absorber in Solutions of Fissile Material. ANSI/ANS-8.21-2023 provides guidance for the use of neutron absorbers, including Raschig rings, as an integral part of nuclear facilities equipment, fissile material, or fuel components outside reactors, where such absorbers are credited to provide criticality safety control.
