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.

An open letter to Chris Wright
Craig Piercycpiercy@ans.org
Dear Secretary Wright:
On behalf of the U.S. nuclear professional community, I offer our sincere congratulations to you on your becoming the secretary of energy.
By now, I’m sure you have figured out that “Department of Energy” is a misnomer. If the Department of Government Efficiency ever requires truth in advertising, the DOE should be renamed the “Department of Nuclear Weapons, Security, Cleanup, and Sundry Energy and Science Programs.” That’s because more than 60 percent of the DOE’s budget is dedicated to “atomic energy defense activities”—making sure our nuclear bombs work, our aircraft carriers and submarines sail, and our Cold War messes get cleaned up.
