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 neutron capture cross section of 99Tc has been measured relative to the 10B(n,) standard cross section by the neutron time-of-flight (TOF) method in the energy range of 0.005 eV to 47 keV using a detection assembly of Bi4Ge3O12 scintillators and a 46-MeV electron linear accelerator at the Kyoto University, Research Reactor Institute. The relative measurement has been normalized at 0.0253 eV to the reference value (22.9 ± 1.3 b) measured by Harada et al. The energy-dependent experimental data and the evaluated data in ENDF/B-VI, JENDL-3.2, JENDL-3.3, and JEF-2.2 are in general agreement with the current measurement. In particular, the JENDL-3.3 data, which have been released recently, show better agreement with the measurement in the lower-energy region.The resonance parameters at 5.6 and 20.3 eV have been analyzed by the KALMAN system using the current TOF data. The resonance integral calculated with the parameters obtained is derived to be 330 ± 19 b, which is close to the data obtained from JENDL-3.3 and evaluated by Mughabghab, although the resonance integrals from JENDL-3.2, ENDF/B-VI, and JEF-2.2 are smaller by ~6 to 8% than the current value. The resonance integral data measured by Harada et al. is larger by ~20%.
