ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Nuclear fuel cycle reimagined: Powering the next frontiers from nuclear waste
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
Educational Session|Panel|Sponsored by Plant Reliability
Tuesday, August 6, 2024|1:30–3:00PM EDT|Banyan 2
Parts quality is foundational to a reliable plant. This was affirmed by INPO IER 21-4 (Improving Plant Reliability) in 2021, which included an action to “establish a sustainable parts quality process.” Despite the industry expectation and importance of establishing and maintaining a robust process, there is no single approach used by utilities to implement a parts quality process.
This session will discuss the many approaches the industry has taken to align with INPO’s IER as well as highlight best practices and lessons learned. Key elements covered in this session include:
• Critical part issues that are affecting safety and reliability today.
• Causes of critical part failures and the importance of accurate causal evaluations and failure analysis.
• Importance of supplier performance program engagement.
• Approaches for (and examples of) implementing the recently published INPO What Excellence Looks Like (WELL) sheet, which was provided to help reduce plant reliability events caused by faulty parts and components.
