Energy that originates from the splitting of uranium atoms in a process called fission. This is distinct from a process called fusion where energy is released when atomic nuclei combine or fuse.

Campanell wins Lawrence Fellowship to pursue plasma physics research

Princeton University graduate student Michael Campanell has won a highly competitive Lawrence Fellowship, resulting in a postdoctoral position at Lawrence Livermore National Laboratory. Campanell was one of just two candidates selected from a field of 163 applicants for the coming academic year for the fellowship, which is open to all technical disciplines.

“I was thrilled to receive this fellowship,” Campanell said. "I think it is the best possible fit for me."

COLLOQUIUM: Nuclear Famine: The Threat to Humanity from Nuclear Weapons

A nuclear war between India and Pakistan, with each country using 50 Hiroshima-sized atom bombs as airbursts on urban areas, would inject smoke from the resulting fires into the stratosphere. This could produce climate change unprecedented in recorded human history and global-scale ozone depletion, with enhanced ultraviolet (UV) radiation reaching the surface.

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.

Plasma Turbulence Simulations Reveal Promising Insight for Fusion Energy

With the potential to provide clean, safe, and abundant energy, nuclear fusion has been called the “holy grail” of energy production. But harnessing energy from fusion, the process that powers the sun, has proven to be an extremely difficult challenge.

Scientists have been working to accomplish efficient, self-sustaining fusion reactions for decades, and significant research and development efforts continue in several countries today.

The Bleeding ‘Edge’ of Fusion Research

Few problems have vexed physicists like fusion, the process by which stars fuel themselves and by which researchers on Earth hope to create the energy source of the future.

By heating the hydrogen isotopes tritium and deuterium to more than five times the temperature of the Sun’s surface, scientists create a reaction that could eventually produce electricity. Turns out, however, that confining the engine of a star to a manmade vessel and using it to produce energy is tricky business.

PPPL extends system for suppressing instabilities to long-pulse experiments on KSTAR

PPPL collaborations have been instrumental in developing a system to suppress instabilities that could degrade the performance of a fusion plasma. PPPL has built and installed such a system on the DIII-D tokamak that General Atomics operates for the U.S. Department of Energy in San Diego and on the Korea Superconducting Tokamak Advanced Research (KSTAR) facility in South Korea —  and now is revising the KSTAR design to operate during extended plasma experiments.

Two PPPL-led teams win increased supercomputing time to study conditions inside fusion plasmas

Researchers led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won highly competitive allocations of time on two of the world’s fastest supercomputers. The increased awards are designed to advance the development of nuclear fusion as a clean and abundant source of energy for generating electricity.
