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 “infinitely dilute” resonance integral is considered in the unresolved region. The gamma-ray and fission widths are assumed constant so that the height of any resonance depends only on the resonance energy and the reduced neutron width. On the basis of this assumption, the γ'th moment of the area under the profile of an isolated resonance may be written as a combination of the integrals Any such integral may be expressed in terms of the integrals corresponding to j = 0 and j = 1, which are easily determined. Next, an expression for the γ'th moment of the resonance integral is derived for the case where resonances are scattered over an energy interval. In view of the lack of absolute unanimity among workers in this field, the derivation is performed without making any specific assumption about the level spacing distribution, allowance being made for energy dependence. From the results for an isolated resonance, this expression is capable of evaluation for any particular value of γ, once the form of the level spacing distribution has been chosen and the resonance density calculated.
