Dr. Won Sik Yangs has been named a fellow of the American Nuclear Society (ANS). He will receive the award in November at the ANS Winter Meeting during the President's Special Session.

He is recognized for the development of the premier high fidelity reactor physics software package in the world for fast reactor analysis.  Under his technical leadership, the software package systems were developed under the DOE NEAMS program which has had a dramatic impact on the design and analysis of advanced GEN-IV fast reactor cores and the viability of closed fuel cycles for Transuranic and Minor Actinide Burning.

The honor of fellow is given to those with distinguished contributions in the field of nuclear science and engineering, who then serve as advisors to the society.
