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.

Pacific Fusion predicts “1,000-fold leap” in performance, net facility gain by 2030
Inertial fusion energy (IFE) developer Pacific Fusion, based in Fremont, Calif., announced this morning that it is on target to achieve net facility gain—more fusion energy out than all energy stored in the system—with a demonstration system by 2030, and backs the claim with a technical paper published yesterday on arXiv: “Affordable, manageable, practical, and scalable (AMPS) high-yield and high-gain inertial fusion.”

This paper summarizes the work done to update the PACTOLE code, developed for Pressurized Water Reactors (PWRs) to predict the level of activated corrosion products in their cooling loops. The aim is to use it in safety analysis for the International Thermonuclear Experimental Reactor (ITER) project.
In particular the adaptation has focused on the implementation of copper as a new element in the code by using the findings obtained from “ad hoc” experimental tests. The updated release of the code, named PACTITER, has been extensively used to predict in particular the source term inventory of the ITER divertor primary heat transfer system (PHTS) and the related collective dose to the staff in the supporting activities for the Non-Site Specific Safety Report n.2 (NSSR-2).
