Princeton and PPPL share in $25 million nuclear arms-control project

The National Nuclear Security Administration (NNSA) has named Princeton University and the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) participants in a new $25 million, five-year project to address technology and policy issues related to nuclear arms control. The project will include a unique process that Princeton and PPPL are developing to verify that nuclear weapons to be dismantled or removed from deployment contain true warheads.

COLLOQUIUM: Uncovering the Hidden Skeleton of Flow Transport

Recent years have seen several major environmental disasters throughout the Earth’s oceans, such as the the Deepwater Horizon oil spill and the Tohoku Tsunami that caused the release of substantial amounts of debris and radioactive contamination. In each of these disasters, material was released from what was essentially a point source into the environmental flow, and understanding how this material would be transported was of paramount importance.

COLLOQUIUM: Risks of Nuclear Weapons Use in an Era of Proliferation, Cyber Warfare and Terrorism

The United States and eight other countries that possess nuclear weapons run myriad risks every day -- risks of accidental detonations, of unauthorized launches caused by false warning, of provoking escalation between nuclear forces, and of nuclear weapons falling into the hands of terrorists.

Fusion through the eyes of a veteran science journalist

Author Daniel Clery recently published “A Piece of the Sun,” a 320-page narrative of the history of fusion research and the personalities who have devoted their careers to it. Clery is a United Kingdom-based reporter for Science magazine who holds a bachelor’s degree in theoretical physics from York University and has covered fusion for more than a decade. While hardly an uncritical flag-waver for fusion, he recognizes its vast potential. He discussed his new book and the future of fusion with PPPL Science Writer John Greenwald.

PPPL honors physicists Steven Sabbagh and Gregory Hammett

PPPL presented its 2013 outstanding research awards to physicists Steven Sabbagh and Gregory Hammett following Director Stewart Prager’s May 28 State-of-the-Laboratory Address. Sabbagh received the Kaul Foundation Prize for Excellence in Plasma Physics Research and Technology Development for his work on advancing the understanding, and enhancing the stability, of high-performance plasmas in fusion facilities called tokamaks. Hammett was named winner of the Distinguished Research Fellow Award for his work on deepening the theoretical understanding of turbulence in fusion plasmas.
