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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

A set of simple scaling relations is derived to assess the impact of plasma physics and technology assumptions on the design of a DEMO tokamak fusion reactor. At the same time, it is shown that by postulating that the plasma physics assumptions are consistent with those that can be reliably reached in present-day experiments and that the recirculating power is reasonably low, a tokamak DEMO operating with steady-state plasma operation is of large size, comparable to a reactor - suggesting that the study of pulsed options should receive more attention in the future. The scaling relations reproduce well the results from a number of previous studies, indicating that they are particularly well suited for future parametric scoping studies. From the relations derived, it also follows that the areas in which future progress will have a particularly large impact on the attractiveness of DEMO are the limit in plasma physics and in technology the magnetic field strength Bt and the wall-plug efficiency CD of the systems to drive noninductive current.
