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.

Resonance parameters for 74 resonances of 165Ho below 500 eV, selected from the literature and from values compiled and recommended in BNL-325, are used as the starting point in fitting the total neutron cross-section data to a sum of the Breit-Wigner multilevel scattering and single-level capture formulas. The addition of two bound levels, one for each s-wave spin state, yields a calculated ratio of thermal neutron capture cross sections for the two s-wave spin states which agrees with experiment (≈60% of thermal capture into J = 3 states), as does the calculated value of the thermal capture cross section, 67 b. In addition, the two bound levels enable the fit of the total cross-section data to be extended to very low energies (0.2 mV). The coherent scattering cross section has been calculated and is in good agreement with the experimental value of 9.1 b. The free atom nuclear scattering cross section has been calculated to be 10.6 b. The calculated value of the potential scattering is 7.8 b and the effective scattering radius is 7.9 f. The energy-dependent paramagnetic scattering cross section (23.5 b at 0.0253 eV) and the capture and scattering resonance integrals have also been calculated (≈703 and 125 b, respectively).
