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.

The solubility of a nickel ferrite, NixFe3-xO4, as a model substance for deposits forming on the cladding of nuclear fuel elements of pressurized water reactors is determined in aqueous solutions of primary coolant composition at different pH and hydrogen concentrations, in the temperature region from 230 to 330°C. The temperature coefficient of solubility changes from negative to positive at about pH 7 with increasing pH. The data agree reasonably well with those of Sweeton and Baes for magnetite, considering the lower iron activity in the nickel ferrite. The solubility of nickel is generally lower than that which corresponds to a congruent solution and goes through a minimum near pH 7.4. The iron solubility appears to depend on the one-third power of the hydrogen concentration in solution in the region from 20 to 100 cm3 H2/kg H2O, as expected. Preliminary results, however, indicate that at lower hydrogen concentrations, the dependence on the hydrogen concentration can decrease, possibly due to the formation of cation vacancies.
