ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The boost and damping of the level of potential fluctuations are reproduced in imitation experiments with an electron beam driven discharge in the linear open system. The most pronounced instability of the sheath potential drop is observed in hydrogen plasmas in the presence of small admixtures of oxygen for materials which form oxides with enhanced emissivity of secondary electrons. Measurements of the plasma fluctuations level are in a qualitative agreement with analytical analysis of temporal evolution of plasma -surface interaction as function of internal and external electric circuit parameters.
The surface currents which appear between zones with different emissivity and are closed by the bulk of the incident plasma flow have been studied with the use of the two-plate collector. It is shown that these currents can crucially influence the plasma turbulence.
