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.

Bill would eliminate public hearing requirement in nuclear licensing
A bill being considered in the U.S. Senate seeks to remove the requirement for the Nuclear Regulatory Commission to hold a public hearing for every nuclear reactor application.
Current law requires public hearings to be held by the NRC toward the end the all reactor license application process, in addition to the statutorily required environmental and safety reviews that provide public engagement opportunities for stakeholders and citizens.
