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.
Actions taken to prevent nuclear and radiation accidents or to limit their consequences.
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.
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.
Leading experts from around the world gathered at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) in July to focus on a key issue for the development of fusion energy: Improving ways to predict and mitigate disruptions that can destroy magnetically confined plasmas that are needed for fusion reactions.
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 is one of the 17 national laboratories sponsored by the U.S. Department of Energy, and one of 10 overseen by the Department's Office of Science, the single largest supporter of basic research in the physical sciences in the United States.
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.
