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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Using a 1-D particle code, we have analyzed characteristics of an Inertial Electrostatic Confinement Fusion device with external ion source which is added to enable low pressure operation. When the pressure becomes low, though neutron yield decreases, the decreasing amount is less than estimated from the decrease in background (target) gas density and it is confirmed that ions are accelerated efficiently with little energy loss through charge-exchange collision with background gas at low pressure. And when the pressure is lower than 0.05Pa, almost all injected ions reach to the cathode and it is expected that applying high geometrical transparency enhances accumulation of ion and enlarges neutron yield.
