Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Achieving high-performance long-duration plasma discharges in tokamaks is one of the most important challenges to be addressed in the perspective of the development of a power plant. For this purpose, real-time handling of off-normal events has to be performed through a dedicated plasma discharge management system. In this paper, we describe the main requirements and features of such a system. A generic architecture, based on the principle of subsidiarity, is proposed. A full set of actions is covered, starting from the local subsystems up to the tokamak as a whole, with different levels of mitigation strategies. A simulation of a relevant test case, based on the Tore Supra tokamak, showing the basic principles of the study, is also presented.
