John Galayda knows long-term commitment. Just ask his pet turtle, Opie, who's 20. Fortunately, for the Linac Coherent Light Source (LCLS) project at DOE's Stanford Linear Accelerator Center, Galayda also knows physics. “I was a Sputnik kid,” said Galayda, who became a Fellow of the American Physical Society in 1996. “When I was growing up I never considered any other career besides science.” Galayda's abiding fascination with science at the dawn of the space age has led him to the forefront of 21st Century physics, as director of the LCLS project, now under construction at SLAC. Galayda's qualifications as LCLS project director stem from an entire career building particle accelerators. While working as a physicist for Brookhaven National Laboratory's National Synchrotron Light Source, Galayda had a hand in all aspects of accelerator construction, from magnet and RF cavity design to electron beam control systems. In 1989, Galayda and his team received an R&D100 award for their innovative system for stabilizing the electron beam within Brookhaven's storage ring. After 13 years at Brookhaven, Galayda moved to the Advanced Photon Source at Argonne National Laboratory, where he directed the construction, commissioning and operation of the APS accelerators. In 1996, his organization transformed the APS injector into Argonne 's free electron laser, which operated in visible to ultraviolet wavelengths. Now, Galayda brings the lessons learned at Brookhaven and Argonne to the LCLS project. LCLS will be an even more powerful free electron laser, using the final 1/3 of SLAC's existing linear accelerator to produce ultra-fast pulses of X-rays a billion times brighter than any other source on earth. As a man who claims to have “found out the hard way” that turtles are not allowed aboard airplanes, Galayda understands creative problem solving. This, in fact, is what he rates as his favorite aspect of managing physics projects such as the LCLS. “It's one thing to think about designing accelerators," said Galayda, “but it's a whole other thing to make one happen. I have to be aware of all the different ingredients—I'm never bored. It's a fascinating challenge.” The LCLS project is a collaboration among DOE laboratories including SLAC, Argonne, Brookhaven, Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and the University of California Los Angeles.

Collaboration moves forward on Advanced Fuel Cycle FacilityA team of engineers from national laboratories, universities and industry is moving forward on conceptual design work for the Advanced Fuel Cycle Facility, a vital component to establishing an acceptable nuclear fuels recycling program under the Global Nuclear Energy Partnership (GNEP).
When completed around 2014, the AFCF will essentially be a versatile nuclear fuels research campus - the world's premier proving ground for tomorrow's advanced nuclear fuel cycle technology. “This project will provide a place to continue to advance technology in nuclear fuel for at least 50 years,” said engineer Wayne Ridgway of DOE's Idaho National Laboratory. Ridgway is managing a national project team of engineers from Idaho National Laboratory, Argonne National Laboratory, Brookhaven National Laboratory, Los Alamos National Laboratory, Oak Ridge National Laboratory, Pacific Northwest National Laboratory, Sandia National Laboratory, SRS Technologies, Washington Group International and various universities. The AFCF team is charged with designing a flexible, integrated testing and demonstration facility. Running at a fraction of the capacity of a full-scale commercial plant, it will help researchers prove that new nuclear fuel recycling processes, such as pyroprocessing, can work on a commercial scale. To support the anticipated demand of the commercial nuclear industry for demonstration of integrated fuel cycle processes, the facility will be equipped to carry out engineering scale demonstrations in a number of fuels-related areas, including separating the components of spent nuclear fuels, advanced aqueous separations, advanced pyrochemical separations, fabricating transmutation fuels, advanced waste forms and advanced safeguards. Advanced fuels for Global Nuclear Energy Partnership nuclear reactors will also be designed and tested there. The long-term goal of the DOE-owned facility will be to bring the U.S. back up to speed in nuclear fuel cycle technology. “We're revitalizing our expertise in this country,” Ridgway said. “We're basically reviving core competency in nuclear technologies and we need a place to do that. You can build up universities all you want but until the students have a place to demonstrate the science and technology, their progress is limited.” The actual site for the facility is pending on the results of an environmental impact statement being prepared for several potential locations.
