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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

The distribution in water of indium resonance neutrons from a 1.4 Mev D-D source has been measured in planes perpendicular to the deuteron beam up to 28 cm in the forward direction from the source. The values of the integrated activities over the planes (including the extrapolated region beyond the range of measurements in each plane) are presented. In addition, a method is described for inferring an age from a D-D source by finding an angle where the distribution is equivalent to that from an isotropic and monoenergetic source. The age of indium resonance neutrons obtained for an equivalent source at 4.3 Mev is 54.4 ± 1.4 cm2. Comparison is made with calculated values of the age.
