Activities for National FNS/TBM Effort (FY08)

  • Perform R&D: Theory, Modeling, and Laboratory Experiments for Top Level, Fundamental FNST issues needed for all scenarios

    • Principal target areas include LM-MHD, Thermofluid, Tritium, Nuclear, Materials (broaden the participation of other US FNS programs)

  • Fulfill all US obligations and milestones related to TBM for IO and TBWG, e.g. Safety, ITER-Interface, etc

  • Support DOE with technical and programmatic information necessary to develop US position (e.g. high level Ad-Hoc Group negotiations)

  • Carry out design, analysis, and other technical activities that potentially have the highest relevance to developing realizable US and international TBM testing strategies

    Options: (Option A will be the primary focus)

    • Continue US ITER TBM reference scenario - DCLL as the prominent US TBM concept, and HCCB with submodule-scale supporting role

      • Define critical DEMO-relevant science and feasibility FNS issues that can be addressed by TBM

      • Improve TBM design and testing plans

      • Foster and implement international TBM collaborations

    • Develop details of effective supporting research role

      • evaluate possible collaborating parties and concepts

      • determine if aspects of US DCLL and HCCB can be tested as part of another parties TBM

    • Develop international TBM common strategy

      • compare concepts proposed for ITER testing by other parties

      • evaluate and select the 2 or 3 with greatest potential, develop better scientific testing plan

  • Evolution and Innovation of FW/Blanket (if extra funding)


Continue us iter tbm reference scenario

Continue US ITER TBM reference scenario

  • Skeleton design for half-port DCLL in DT phase

    • Becomes focus of tool development, R&D definition, and analysis effort

    • Design in flexibility for later modifications and possibly multiple submodules

  • Research on Key Issues

    • Disruption analysis

    • Tritium permeator to low partial pressure – impact of PbLi (impurities, diffusivities…), vacuum side

    • PbLi Gap impact on local tritium partial pressure

    • FCI stress, deformation, and dT limits

    • MHD/FCI conditions and design impacts
