  1. Status of Disruption Simulations for FIRE C. Kessel, PPPL NSO/PAC Meeting, University of Wisconsin, July 10-11, 2001

  2. Disruption Simulations for FIRE • Disruption scenarios • VDE (drift and disrupt) • Radial disruption (on midplane) • Vertically offset disruption (Zp=2-5 cm off midplane • Plasma parameter examination • Halo temperature and width • Thermal quench time • Target dIp/dt and I(halo) from ITER database • Numerical convergence issues

  3. Disruption Simulations for FIRE • Structure variations • Examine copper additions to VV for cooling • Create toroidally continuous current path thru divertor modules to avoid large local currents • TSC provides plasma evolution and timing for structure analysis • Plasma wire currents throughout disruption for use in 3D structure codes • Currents, fields and forces are calculated in TSC for axisymmetric structure model

  4. Structure Modelling used in TSC

  5. VDE Simulation with 3 MA/ms Current Quench
