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.

The current pace of development of laser-driven fusion together with the urgency of providing sources of safe, clean, low-cost electrical energy have prompted consideration of the major materials problems that must be solved before practical laser fusion can be realized. Many of the materials problems associated with laser fusion are common also to magnetically confined fusion reactors. These include the degradation in physical and mechanical properties of structural materials from neutron irradiation and the formation of interstitial gas, problems related to the use of lithium as a reactor coolant, and the necessity to breed tritium for use in the fuel cycle. Some materials problems are unique to laser fusion. Laser-beam transport requires the use of windows and mirrors that may be damaged by intense laser light. Cyclic stresses imposed on reactor-cavity and blanket-region wall structures accentuate the importance of radiation-induced changes in elastic moduli of structural materials.
