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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

Neutron capture by isotopically purified 232Th was measured at the Oak Ridge Electron Linear Accelerator. The pulse-height weighting method was used with small liquid scintillators to measure the prompt gamma-ray energy release following neutron capture. Resonance parameters were derived up to 10 keV. The average radiative width was (19.8 ± 0.2 statistical ± 0.4 systematic) meV for 50 resonances in the 2.6- to 4.0-keV interval. Strength functions 104S0 = 0.365 ± 0.024, 104 S1 = 1.078 ± 0.057, 104S2 > 0.842 ± 0.084, and y/D0 = 0.0198/(13.24 ± 0.71) were found to fit the average cross section well (to 105 keV) when allowance was made for p-wave inelastic competition above the ∼50-keV threshold. While the values stated gave the best fit (from 2.6 to 105 keV) when all four were allowed to vary, it is likely that “acceptable” fits could be forced for other values. Recent evaluations of the cross section range from 8 to 50% higher than results reported here.
