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.

Report touts lessons from era of nuclear waste negotiator
As the Department of Energy embarks on its consent-based process for siting a geologic repository for spent nuclear fuel and high-level radioactive waste, a new report from the Center on Global Energy Policy at Columbia University SIPA highlights relevant lessons from the federal government’s now defunct Office of the Nuclear Waste Negotiator.
Established under Title IV of the Nuclear Waste Policy Act, the office, an independent agency within the executive branch, was primarily active from 1990 to 1995. Its role was to engage with state and tribal governments to find an acceptable and suitable host site for a repository.
The full report, Lessons from the Nuclear Waste Negotiator Era of the 1990s for Today’s Consent-Based Siting Efforts, is now available online. Its executive summary is available here.
