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.”

Tungsten (W) is a promising candidate as for the plasma-facing material in future nuclear fusion reactors. The interstitial helium (He) atoms in bulk tungsten will degrade seriously the mechanical properties of tungsten. In the present paper the effect of interstitial He atoms on the production and evolution of defects in irradiated tungsten has been investigated using molecular dynamics (MD) simulations. Under the conditions of different primary-knocked atom (PKA) energies and irradiation temperatures, it is found that the interstitial He atoms increase the generation of Frenkel pairs, and this tendency can be greatly promoted by increasing the PKA energy and irradiation temperature. The interstitial He atoms can also increase the displacement cascade efficiency and impact greatly on the structure of radiation-induced defects in tungsten.
