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.

Hinkley Point C gets over $6 billion in financing from Apollo
U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

The accuracy of unfolding neutron spectra with threshold activation foils was investigated by comparing the unfolded spectra with “known” spectra obtained from calculations verified with more accurate spectrometry techniques. Because of the lack of spectral data below 1 MeV (only one useful activation threshold exists between 0.01 and 1 MeV), reliable results are generally obtained only with the a priori constraint of a physically complete trial spectrum. A family of trial spectra useful for reactor spectra [and any nuclear “evaporation” spectra, such as from high-energy (γ, n) reactions] has been formulated. The sensitivity of the solution to the specific unfolding code used, to the threshold-foil cross sections and related nuclear data, and to foil-activation measurement accuracy was also investigated.
