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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

In the course of the recent rehabilitation of CP-5, a study was made of the safety problems associated with in-leakage of light water into the primary coolant (heavy water) stream from a tube rupture in the main heat exchanger. The reactivity effects of the light water can be represented by a prompt positive coefficient and a delayed negative coefficient during normal operation. When the rods are pulled out (as during recovery from xenon poisoning), the effects of light water are to decrease the reactivity. The plant is designed to render water in-leakage highly unlikely. Even in the case such in-leakage occurs, the plant protection system is capable of protecting the system against rupture of many tubes in rapid succession.
