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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Capsule fill tube assemblies (CFTAs) consist of an ablator capsule and fill tube via a laser-drilled funnel hole. This hole tapers from 17-μm diameter at the outer surface of the ablator capsule to less than 5-μm diameter on the inside of the capsule over approximately 200 μm of wall thickness. Demand for better understanding of the fill tube perturbation during the capsule implosion has driven advancements in the fill tube design. Engineering efforts have been made on hydrodynamic growth radiography assemblies (HGRs) using multiple tube-design variations, including alternative angles, depths, sizes, and location with engineered defects to showcase fill tube effects during an implosion. Testing has shown that these CFTAs and HGRs have survived all fabrication and transport to and from General Atomics (GA) to Lawrence Livermore National Laboratory. These assemblies have also passed cryogenic testing at GA. An overview of alternative CFTA designs, fabrication methods, and developments is presented.
