  1. Fusion Materials/Nuclear Science: The Future Presented by: G. R. Nardella Program Manager Office of Fusion Energy Sciences Office of Science U.S. Department of Energy August 3, 2010

  2. Thank you for your attention- Now Chuck Kessel, our starting quarterback and number one draft pick, will speak and answer all of your questions

  3. Background: Setting the Stage • Build on Greenwald, ReNeW and other previous work • Seek partnerships and utilize the community’s technical expertise • Establish the credibility/case for fusion both inside and outside DOE • Burning Plasmas/ITER is the top priority • Recognize the realities of the situation • Synergy between MFE and IFE is potentially high • Community input will be sought and FESAC charges will be developed at the appropriate time

  4. This activity focuses on Materials in a fusion environment • Plasma/surface interactions: establishing boundary of a fusion plasma. Plasma facing surface survival, renewal: cracking, annealing. Fuel retention. Important for industrial, non-energy applications as well • Nuclear effects on materials and structures, including the effects of > 100 dpa on structure integrity, helium creation in situ, and time evolving properties • Harnessing fusion power depends on the nuclear material science above and is extended to tritium breeding and extracting fusion power This requires the launching of a vigorous materials and nuclear science program that will be part of defining and constructing a fusion nuclear science facility, and will fill gaps en route to a DEMO. Such a program will benefit from and give to other research needs. Synergies will be identified and levered between MFE, IFE, advanced nuclear energy, and defense.

  5. The Plan • The July 23 meeting was an opportunity to present our thoughts and to get feedback • Various approaches with their accompany risks must be understood • Identify research requirements to the point of enabling FES to craft calls for proposals and design programs • Adjust the program to meet the materials/nuclear science challenge

  6. Conclusions • Aim to cap this line of research with a major facility, operating in parallel with ITER, but our near term priority is the requisite research program prior to such a facility • Clarify requirements for a nuclear and non-nuclear materials science program that must be deployed prior to the final definition and launching of a major facility
