Digital-twin-based improvements to diagnosis, prognosis, strategy assessment, and discrepancy checking in a nearly autonomous management and control system
ANNALS OF NUCLEAR ENERGY, 166.
Contributors: L. Lin n, P. Athe n , P. Rouxelin n, M. Avramova n, A. Gupta n, *, J. Lane*, N. Dinh n
author keywords: autonomous control; digital twin; diagnosis; prognosis
TL;DR:
This study refines a NAMAC system for making reasonable recommendations during complex loss-of-flow scenarios with a validated Experimental Breeder Reactor II simulator, digital twins improved by machine-learning algorithms, a multi-attribute decision-making scheme, and a discrepancy checker for identifying unexpected recommendation effects.

Machine-learning based error prediction approach for coarse-grid Computational Fluid Dynamics (CG-CFD)
PROGRESS IN NUCLEAR ENERGY, 118.
Contributors: B. Hanna n, N. Dinh n , * & I. Bolotnov n
author keywords: Coarse grid (mesh); CFD; Machine learning; Discretization error; Big data; Artificial neural network; Random forest; Data-driven
TL;DR:
The proposed CG-CFD method has proven capable of correcting the coarse-grid results and obtaining reasonable predictions for new cases and shows potential for a good predictive capability.

2019 journal article
A data-driven framework for error estimation and mesh-model optimization in system-level thermal-hydraulic simulation
NUCLEAR ENGINEERING AND DESIGN, 349, 27–45.
author keywords: Coarse mesh; Error estimation; System-level modeling and simulation; Machine learning; Physical feature
TL;DR:
A data-driven framework is formulated and demonstrated to estimate simulation error and suggest optimal selection of computational mesh size and constitutive correlations for low-f fidelity, coarse-mesh thermal-hydraulic simulation, in order to achieve accuracy comparable to that of high-fidelity simulation.
