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.
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.

When a nuclear plant closes
Theresa Knickerbocker, the mayor of the village of Buchanan, N.Y., where the Indian Point nuclear power plant is located, is not happy. What has gotten Ms. Knickerbocker’s ire up is the fact that Indian Point’s Unit 2 was closed on April 30, and Unit 3 is scheduled to close in 2021. The village, population 2,300, is about 1.3 square miles total, with the Indian Point site comprising 240 acres along the Hudson River, 30 miles upstream of Manhattan. Unit 2 was a 1,028-MWe pressurized water reactor; Unit 3 is a 1,041-MWe PWR.
The nuclear plant provides the revenue for half of Buchanan’s annual $6-million budget, Knickerbocker told Nuclear News. That’s $3 million in tax revenues each year that eventually will go away. How will that revenue be replaced? Where will the replacement power come from?

This work presents the effects that produce the change in entropy during separation processes; it takes into account the dilution of UF6 in a carrier gas (H2, He, N2, Ar, Xe, SF6, etc.). Comparisons were made between two technologies: one a mature process currently used, i.e., centrifugation (process A), and the other in development, i.e., processes based on a laser [Condensation Repression Isotope Separation by Laser (CRISLA), Molecular Laser Isotope Separation (MLIS), etc.] (process B). The calculations were made using the principles of mix thermodynamics. The results indicate that entropy expenditure is two orders of magnitude higher than that necessary to separate isotopes when the amount (of isotopes) is the same in both process A and process B.
