Systems, methods, and storage media for improving fusion energy output by simulating fusion generator components and processes are disclosed. Exemplary implementations may: obtain sets of fusion generator operation information; train a machine-learning model with the obtained sets of fusion generator operation information such that the machine-learning model predicts physical behavior of one or more components of the one or more fusion energy generators based on the one or more fusion process or component parameters; store the trained machine-learning model; and simulate, using the stored machine-learning model, interactions of the one or more components of the one or more fusion energy generators during operation of the one or more fusion energy generators.
