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.

An absolute scale for the differential cross sections of the reactions 3H(p, n)3He, 2H(d, n)3He, and 3H(d, n)4He, measured for incident energies between 6 and 17 MeV, was established using a calibrated time-of-flight system. Accurate charged-particle reference cross sections were inter-compared so that a common scale with an uncertainty of ±1.5% was obtained. By interchanging the target and beam nuclei, data were obtained at 180 deg in the original system for several cases. The new data were analyzed together with the previous data, and Legendre coefficients were extracted to permit presentation of the data between ∼5 and 20 MeV, thus extending and partly revising previous evaluations. The typical shape error of the angular distributions, as given by the Legendre coefficients, is <3% over the entire angular range. In addition, data on the neutron production at zero degree by breakup are given for the p-T and d-D reactions. By correcting the previous counter telescope data for the 1H(n, n)1H cross sections (according to more recent phase-shift analyses), scale ambiguities of ∼3% were resolved, thus indirectly verifying these phase shifts up to neutron energies of ∼16 MeV. However, at higher energies (above ∼23 MeV) for 3H(d, n)4He data, the corrected neutron counter telescope data deviate from the present analysis by ∼5%. Whether or not this difference is caused by the 1H(n, n)1H reference cross section used is open to further investigations.
