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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

We examined the difference of the heating characteristic by the injection condition of the ECRH from the measurement of the soft X-rays representing the electron temperature. The line integrated intensity of soft X-ray (IsxL) in X-mode ECRH (the best absorption) increased to 5.8 times of that without ECRH and 3.4 times in O-mode (the worst absorption). The MCP signal ratio of the different absorbers (Pe2/Pe1.5) increased from 0.43 before ECRH to 0.56 during ECRH of X-mode and from 0.47 to 0.52 in O-mode. It is confirmed the electron heating by ECRH qualitatively in both cases. However the ion stored energy decreased in O-mode ECRH. This results show that it is important to maximize the first pass RF absorption at the resonance layer on axis for the efficient electron heating and avoidance of the confinement degradation of plasma.
