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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

This manuscript reports the high density plasma production with a pair of phase controlled ion-cyclotron range of frequency antennas in GAMMA 10. For the plasma production, the Radio Frequency (RF) power (~10 MHz) is coupled to the fast Alfvén wave in the central cell. The antenna-plasma coupling depends strongly on the antenna structure. In this study, according to the numerical prediction, a pair of double half-turn and Nagoya Type-III antennas is adopted for the excitation of the fast wave. The antennas are driven at the same frequency with controlling their phase difference. It is observed that an optimum phase difference exists in the present density range. The density increases with the RF power and the gas-fuelling rate, when the phase difference is set to the optimum value. The considerable increase in the density was obtained up to twice as large as the conventional value.
