When the ITER experimental fusion reactor begins operation in the 2020s, over 40 diagnostic tools will provide essential data to researchers seeking to understand plasma behavior and optimize fusion performance. But before the ITER tokamak is built, researchers need to determine an efficient way of fitting all of these tools into a limited number of shielded ports that will protect the delicate diagnostic hardware and other parts of the machine from neutron flux and intense heat.
Fusion reactor design
The design of devices that use powerful magnetic fields to control plasma so fusion can take place. The most widely used magnetic confinement device is the tokamak, followed by the stellarator.
The Consortium for Advanced Simulation of Light Water Reactors (CASL) is the first U.S. Department of Energy (DOE) Energy Innovation Hub, established in July 2010 for the modeling and simulation (M&S) of nuclear reactors. CASL applies existing M&S capabilities and develops advanced capabilities to create a usable environment for predictive simulation of light water reactors (LWRs).
Scientists participating in the worldwide effort to develop magnetic fusion energy for generating electricity gave progress reports to the 2013 annual meeting of the American Association for the Advancement of Science in Boston. Speaking were physicists George "Hutch" Neilson of the U.S. Department of Energy's Princeton Plasma Physics Laboratory, and Richard Hawryluk, deputy director-general of the ITER Organization. Following are summaries of their presentations.
Previewing the next steps on the path to a magnetic fusion power plant

Physicist John Schmidt, whose profound and wide-ranging contributions to the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) made him a highly respected leader in the worldwide quest for fusion energy, died on February 13 following a brain hemorrhage. He was 72.
Three teams led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won major blocks of time on two of the world’s most powerful supercomputers. Two of the projects seek to advance the development of nuclear fusion as a clean and abundant source of energy by improving understanding of the superhot, electrically charged plasma gas that fuels fusion reactions.
The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has joined forces with researchers in South Korea to develop a pre-conceptual design for a pioneering fusion facility in that Asian nation. The proposed device, called K-DEMO, could be completed in the mid-to-late 2030s as the final step before construction of a commercial fusion power plant that would produce clean and abundant energy for generating electricity.
Research to develop fusion energy has shown “significant progress” in many areas, according to a new report from the Electric Power Research Institute (EPRI), a think tank whose members represent some 90 percent of the electricity produced in the United States. At the same time, the report said that a commercial fusion power plant is at least 30 years away, and called for more research on the engineering challenges.
Goldston is a Professor of Astrophysical Sciences at Princeton University and an international leader in the fields of plasma physics and magnetic fusion energy. He is the author of 220 papers in journals and conference proceedings, and in 1995 co-authored with Paul Rutherford the textbook "Introduction to Plasma Physics." He is a contributing author to five other books. In 1988 he was awarded the American Physical Society Prize for Excellence in Plasma Physics. Goldston is a Fellow of the American Physical Society. From 1997 to 2009, he served as Director of the U.S.
