2023 journal article

Prediction and uncertainty quantification of SAFARI-1 axial neutron flux profiles with neural networks

ANNALS OF NUCLEAR ENERGY, 188.

By: L. Moloko n, P. Bokov n, X. Wu n & K. Ivanov n

author keywords: Uncertainty quantification; Deep neural networks; Bayesian Neural Networks; Monte Carlo dropout
TL;DR: Deep Neural Networks are used to predict the assembly axial neutron flux profiles in the SAFARI-1 research reactor with quantified uncertainties in the ANN predictions and extrapolation to cycles not used in the training process, indicating good prediction and generalization capability.

Lattice physics calculations using the embedded self-shielding method in polaris, Part II: Benchmark assessment

ANNALS OF NUCLEAR ENERGY, 150.

By: U. Mertyurek, M. Jessee & B. Betzler

author keywords: Lattice physics; Benchmark; SCALE; Polaris; KENO; LWR
TL;DR: This paper solves a simplistic example of an infinite, homogeneous diffusion problem using parameters that correspond to a plate-type, Material Testing Reactor fuel assembly and demonstrates how AD can be employed in conjunction with some traditionally used sensitivity analysis and uncertainty propagation techniques.
