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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

The space-independent dynamics of a reactor controlled by xenon and temperature effects is investigated. The boundedness of the solutions for a reactor with a prompt, negative flux coefficient is shown. Criteria are developed for reactor stability. The effect of delayed neutrons and of the time lag between power and temperature on xenon stability is considered and shown to be generally negligible. Nonlinear effects are shown to be important for reactors with negative as well as positive temperature coefficients.
