    1. Build and compare 3-4 different machine learning (ML) algorithms and chose the best model to predict the Critical Heat Flux (CHF) in the reactor core assembly tube for thermal-hydraulic design. 2. Validate the model by using KTH lab experiment data. Compare the predicted ML results with the results from verified correlations and the 2005 Look-Up Table (LUT). Achievements: Successfully prove the traditional LUT CHF prediction is overtrusted and ML outperforms it. Help update the reactor's critical heat flux calculation method for the Royal Institute of Technology and the Westinghouse Electric Corporation.
