After a hiatus of two years due to COVID pandemic, it was finally possible to organize the traditional ITER International School again. A total of 175 Master's, graduate or postdoctoral students gathered at the end of July in San Diego, California, for the
The 2022 ITER International School on ITER Operation Scenarios and Control took place on the campus of UC San Diego, California. A total of 175 Master's, graduate or postdoctoral students participated.
To prepare optimally for ITER operation, accurate operation scenario simulation capabilities need to be developed, often in conjunction with experimental research that identifies and/or validates the necessary simulation models. This requires knowledge of complex operation limits, often determined by the onset of instabilities that may lead to a disruption of the tokamak discharge and termination of fusion power production in ITER. Robust control may prevent operation scenarios from approaching such limits, or avoid the further destabilization of the plasma. Thus, operation limits, control capability and the disruptivity of a tokamak operation scenario are integrally linked. This is especially true for ITER, which needs to share its set of actuators to perform multiple control tasks (with some actuators involved in multiple control tasks) and for which control performance requirements are very stringent given the large plasma magnetic and thermal energies required for fusion power production.
At the school, leading specialists in the field of tokamak control and scenario development and simulations provided many hours of lectures. In order to develop accurate operation scenario simulation capabilities for ITER, knowledge of operation limits, control capability and the disruptivity of a tokamak operation scenario are all essential.
