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.

DOE opens Milestone fusion pilot plant program to new companies and teams
Eight companies were chosen to develop fusion pilot plant designs through the Department of Energy’s Milestone-Based Fusion Development Program just over two years ago. It wasn’t until June 2024 that the DOE announced that protracted negotiations over program metrics had been concluded. Now, two years on, the original eight are “making great progress,” according to Colleen Nehl, program manager for public-private partnerships in the DOE’s Office of Fusion Energy Sciences (FES). Nehl spoke during a June 4 webinar convened on short notice to discuss the latest fusion Milestone news: a fast-tracked opportunity for additional teams to access remaining Fiscal Year 2025 funding for the Milestone program.
