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.

NEA panel on AI hosted at World Governments Summit
A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.

The analysis of two-dimensional fluid flow and heat transfer problems in a finite rod bundle system can be effectively handled by superpositioning the effects of all cylindrical rods present. This method is not limited to symmetrical rod arrangements but can be applied to rods with arbitrary dimensions and orientations. The solution method is illustrated by solving the Poisson and the Helmholtz equations. Numerical results are presented for the solution of the Helmholtz equation in a circular flow channel containing a center rod and a ring with six peripheral rods and with Dirichlet boundary conditions specified on the wall surfaces.
