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 neutron average total cross section of thorium has been measured near 24 keV in an accurate transmission experiment using the time-of-flight method and the iron-filtered-beam technique. The measured average total cross section is 14.933 ± 0.041 b. The computer codes BABEL and MCROSS were used to stochastically calculate average cross sections near 24 keV from several sets of resonance parameters. The average total cross section calculated from the Forman et al. data set is in good agreement with the experimental results, but the cross section calculated from the ENDF/B-IV data set is 16% lower than the measured value. The major part of this 16% discrepancy is attributed to too small a nuclear scattering radius in the ENDF/B-IV data set.
