Massive Gas Injection scheme for ITER’s DMS


Problem Statement:

  • ITER needs a reliable fast acting tool to mitigate the possible sudden unplanned terminations of the plasma that could damage the plasma chamber from thermal loads, high magnetic forces, and runaway electrons. The Disruption  Mitigation System (DMS) consists  of injecting a large quantities of mass into the plasma. The massive gas injection (MGI) is investigated here.

Technical Approach:

  • High pressure gas flow simulations are performed with OpenFOAM to evaluate the different possible  nozzle designs.

Benefit:

  • The CFD simulations allow an exploration and comparison design alternative, minimizing reliance on costly physical prototypes.
