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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.
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.
