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.

A model of the IBR-2 pulsed reactor of periodic operation is developed to facilitate modeling of transitional processes. The model is constructed as a module structure with the help of discrete transitional functions of the kinetics, power feedback, and automatic regulator blocks taking into account nonlinear relationships. Good agreement between the calculated and experimental dependence of changes in the power for different changes in the setting reactivity is achieved. Using the model, power transition processes have been evaluated at different values of the parameters of the automatic power regulator (APR). It has been shown that the best transition processes correspond to higher APR rates at the elimination of the APR smoothing unit. Recommendations are given for choosing the APR parameters.
