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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Small modular reactors (SMRs) are currently framed as a clean energy innovation with a vital role to play in decarbonizing power production. We review two popular sustainability transitions frameworks—strategic niche management and technological innovation systems— for case studies of analogous clean technology innovations. We focus on those that include policy-relevant recommendations that could be applied to the challenges posed by successfully scaling up SMRs from prototypes to commercial production. Particular attention is paid to how each approach understands the linkages between technology and the broader social and economic context. Innovative features of this paper include a systematic review of the lessons from renewable energy case studies for engagement with policy practitioners; reflections on the challenges of applying Euro-centric approaches in the sustainability transitions literature to non-European environments, including remote, northern, and indigenous communities; and some preliminary lessons for policy development that reflect the current situation with SMRs and support evidence-informed decision making in communities currently considering SMRs as part of a future clean energy mix.
