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.

This paper describes the design modifications to the plasma feedback control system, including power supply, for the Upgrade of JT-60. One of the major design issues was to be able to change the kind of control command for the thyristor converter from voltage to current and vice versa at any time during the discharge. Another one was to adopt a faster control system with 250µs response for stabilization of plasma vertical position, even in plasmas with high elongation of 1.8. These modifications improved the plasma controllability especially at initiation and made protecting the poloidal field coil system easier when the plasma disrupts. The high flexibility of the control system led to the achievement of a 4MA plasma after only 2 weeks of JT-60U operation.
