Enhancement of Reflood Test Prediction by Integrating Machine Learning and Data Assimilation Technique

Figure 1

The MARS code model for reflood tests. The test section in the MARS code model was divided into 20 nodes. The heat structures included heated rods, failed rods, thimbles, fillers, and housing. The inlet of the test section was modeled using a time-dependent volume and a time-dependent junction, while the outlet used a single volume and junction, respectively.
