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.

Geological work begins on Poland’s first nuclear plant
Project management firm Bechtel started site geological surveys for Poland’s first nuclear power plant project, the company announced on Wednesday.
Bechtel will conduct in-depth geological surveys at the Lubiatowo-Kopalino site in the Pomeranian municipality of Choczewo, in northern Poland. This is a key milestone for the country’s entry into nuclear power production, as the surveys will inform the suitability of the planned site.

Successful operation of the Versatile Test Reactor (VTR) relies on satisfying stakeholder requirements and guaranteeing customer timelines. Although the VTR leverages proven sodium fast reactor technology, its mission as a test reactor introduces unique design and operational requirements. This paper covers the preliminary analysis and methodology development for two areas of the VTR core design related to the operational flexibility necessary for the testing mission. The first of these introduces a framework for assessing the feasibility of storing used driver fuel in the VTR shield region, which offers potential benefits to operations but may affect core reactivity and increased cooling time. A methodology to assess these impacts using neutronics and depletion calculations is demonstrated on three in-shield storage configurations. The second focus area highlights operational considerations and maximum residence time of the VTR control assemblies, which are critical to maintaining the irradiation environment necessary to deliver on the VTR mission. A preliminary methodology that assesses B-10 depletion and absorber rod swelling is demonstrated with the goal of informing future development. Together, these research activities illustrate how the early-stage VTR design is guided by anticipation of operating objectives.
