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.

This paper presents a method for solving multiregion transport problems which is a generalization of integral transport theory as typified by the well-known Amouyal-Benoist-Horowitz method. The theorem of uniqueness of the solution of Boltzmann equation is used to reduce the problem to a series of associated problems, the Green's functions of which are supposed to be known, with appropriate sources at region boundaries. A system of integral equations is obtained for the sources. The present paper is restricted to one-speed, plane geometry, and infinite medium problems as associated ones. The numerical results presented appear to be very good compared with other methods. Our method provides the advantage of reducing the number of unknowns by an order of magnitude and can therefore provide a comparable reduction in computing time.
