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 research and development (R&D) activity on the negative ion sources at the National Institute for Fusion Science is described. During the R&D period from 1989 to 1998, intensive experimental investigations were carried out at a test stand with three sizes of ion source, 1/6, 1/3, and full size. Although comprehensive research had been carried out, there remained some problems on the Large Helical Device (LHD) beamlines. To resolve those problems, the ion sources and beamlines have been improved in several successive steps since the beam injection experiment of LHD started. Over the past decade, the injection energy, power, and reliability have been increased; the maximum energy now exceeds the 180-keV design value and the maximum injected powers reach 6.8 and 5.5 MW from beamlines 1 and 2, respectively.
