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.

Small proportional counters containing hydrogen and without collimation have measured reactor neutron spectra with resolution adequate for comparison with existing energy-group methods of calculation over the energy range from 1 keV to 1 MeV. The counters are efficient and operate satisfactorily at low (105/cm2 sec) flux levels. Experimental methods currently in use for in-core measurements using proportional counters vary; the one described here makes use of an electronic pulse-shape discrimination to eliminate the background of gamma radiation. The nature of the numerical procedure required to extract neutron spectra from measured energy distributions of recoil protons bears upon the resolution and statistical precision of the result. Examples of measured neutron spectra are given where they illustrate the various points of experimental technique.
