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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

The present status of various deuterium-tritium (D-T) neutron sources is given, including the prospects for improvements. By upgrading a Rotating Target Neutron Source II-type neutron generator, a yield of 1014 n/s can be achieved in a small volume. A yield of 1015 n/s is expected with construction of a gas-jet target. According to a proposal from Kernforschungszentrum Karlsruhe, a similar yield could be reached even with a volume of 500 cm3. Realistic fusion reactor conditions can only be satisfied by high-intensity D-T neutron sources. Other more economical or higher intensity accelerator-based neutron sources cannot replace them in this research field. The lack of sufficient financial support delays technically realistic projects. This difficulty might be overcome by a more intense joint international collaboration.
