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.

How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

A method for studying systems of differential equations employing an interactive computer system with a display screen is presented and applied to three nonlinear problems in reactor kinetics. Interactively it is possible to construct phase space solutions of second- and third-order systems of equations. It is also possible to project from the three-dimensional space and to consider the solutions of the equations as explicit functions of the independent variable. The method is demonstrated on three different nonlinear problems of interest to nuclear reactor kinetics. A second-order problem with temperature-dependent reactivity is considered. Two third-order problems with reactivity a function of two effective temperatures and 135Xe concentration, respectively, are also considered. The method of analysis makes it possible to efficiently study the effect of various parameter values on the solutions of the equations. Limit cycle behavior is investigated and the effect of the parameters of the model on the limit cycles is studied with greater effectiveness than can be achieved by an analytical study.
