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.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

Experimental studies of thermal interactions of cold liquid droplets impinging on metal surfaces have been performed and the result of these studies are summarized in this paper. In these experiments rapid, energetic (explosive) breakup of the liquid drops were observed using high-speed video camera recordings. These energetic interactions occurred over a range of high temperatures of the metal surfaces and varied with the type of metal employed. Three metals were used in the study, namely, copper, brass, and stainless steel. The test sections included curved-plate (sections machined from metal cylinders) and flat-plate geometries. The choice of metals was determined by the objective of establishing the influence of thermal diffusivity of the hot material on the thermal interaction between the cold liquid droplet and the hot metal surface, and the two metal surface geometries were used to study the influence of droplet spreading behavior after impact with the hot metal surface. Metal surface temperatures ranged from 30°C to 700°C and controlled single water droplets at a temperature of 25°C were released from a specially designed rig employing a small fast–opening/closing solenoid valve. Experimental results are presented in this paper that demonstrate the processes that occur during the interaction of the droplet with the hot metal surface during a time frame of 1 to 20 ms.
