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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

We welcome ANS members who have careered in the community to submit their own Nuclear Legacy stories, so that the personal history of nuclear science and technology can be captured. For information on submitting your stories, contact nucnews@ans.org.
I graduated with a mechanical engineering degree from Osmania University in Hyderabad, India, and took up nuclear engineering when I was awarded a scholarship by an organization called His Exalted Highness The Nizam of Hyderabad’s Charitable Trust. That scholarship enabled me to do graduate work at Pennsylvania State University, and I enrolled there in 1966. One of the terms of the scholarship was that I return to India after graduation. Hence, I returned to India in 1972 after receiving my Ph.D. and began working at the Bhabha Atomic Research Centre in Mumbai.

The mathematical basis for a computer code PUNE (Plutonium-Uranium-Non-Equilibrium) is described. The code simulates the steady-state concentration profiles of solvent extraction contactors used in the Purex process under conditions where material transfer between phases deviates from the equilibrium limit. The deviation is accounted for by a mass transfer area characteristic of the operating conditions of a contactor, and a mass transfer coefficient for the chemical species of interest. In the limit of infinite mass transfer rate, PUNE gives the same results as other codes that calculate equilibrium profiles. For 1A and IE contactors, the computational times are reduced between two- and fivefold over times required by other codes that generate the steady-state profiles via transient state conditions. For 1B or partitioning contactors, the reduction in time can be more than 20-fold. Since there is no loss of accuracy in these calculations, PUNE represents an important advance in the determination of steady-state profiles, especially for 1B contactors because it is with these that the greatest computational difficulties are encountered.
