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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

The continuous neutron spectrum from the t→d+n breakup reaction can best be extracted in the 3H(p,n)3He and 4He(t,n)6Li reactions because of minimum neutron background in both cases. Only for the latter reaction are neutron background spectra also available. These data were measured at 11.88-MeV triton energy at eight angles between 0 and 120 deg. As a test for the validity of the procedure, angle-dependent differential cross sections of 4He(t,n)6Li were extracted and converted to 6Li(n,t)4He at En = 2.32 MeV by detailed balance calculation thus contributing to the R-matrix analysis of the 7Li system. The double-differential and neutron energy integrated cross sections at that energy are given as well as those for the triton breakup of the time-reversed reaction.
