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.

IAEA’s updated Milestones for nuclear-curious nations include a focus on SMRs
The IAEA’s Milestones in the Development of a National Infrastructure for Nuclear Power was last revised back in 2015. Now, about nine years later and amid a resurgence of interest in nuclear power, the latest guidance on the IAEA’s Milestones Approach offers updated advice to policymakers in nations looking to introduce a nuclear power program or expand an existing fleet, encouraging them to evaluate infrastructure readiness before seeking bids from reactor vendors. For the first time, the guide includes an “annex” specific to small modular reactor deployments.

The analytic hierarchy process (AHP) provides a decision-analysis framework to model unstructured problems in almost every kind of discipline, whether social science, aerospace engineering, or nuclear reactor safety analysis. As common-cause failure (CCF) has been a major element of incidents and accidents in terrestrial nuclear power reactors because of high redundancy built into the systems and susceptibility of these redundant systems to CCF mechanisms, ad hoc approaches used to be taken to address vulnerabilities to CCF by designers or operating staff of the plants. We show in this paper how the AHP in conjunction with goal-tree success-tree (GTST) methodology can be used to identify an optimal CCF-defense strategy under various constraints (e.g., the largest safety impact, the smallest cost, and the least operator burden). This work demonstrates applicability and effectiveness of the AHP decision-analysis technique in CCF-defense assessment with a novel introduction of the GTST methodology as a tool to construct a hierarchical decision tree for the AHP. The combined approach based on AHP and GTST methodologies can be used not only for CCF-defense assessment but also for any other multicriteria decision analysis requiring priority setting.
