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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

A model for the potential reactor coolant pump seal loss-of-coolant accident in a Westinghouse Electric Corporation pressurized water reactor following a loss of component cooling water (CCW) is developed based on state-of-the-art knowledge. The potential operator recovery actions in coping with a loss-of-CCW event are investigated, and an event tree is constructed to describe the possible core melt sequences. The sequence frequencies are plant specific; however, evaluations (of the sequence frequencies) demonstrate that an emergency operating procedure that clearly identifies possible recovery actions can reduce the core melt probability by two orders of magnitude.
