A Future with Machine Learning: Review of Condition Assessment of Structures and Mechanical Systems in Nuclear Facilities

[Review of ]. ENERGIES, 16(6).

By: H. Sandhu n, S. Bodda n & A. Gupta n

author keywords: condition assessment; artificial intelligence; deep learning; damage detection; signal processing; data management; nuclear piping; concrete; advanced reactors; digital twin
TL;DR: AI can play a greater role in the condition assessment and can be extended to recognize concrete degradation before cracks develop, and data assimilation and storage is another challenging aspect of autonomous control. (via Semantic Scholar)

Limitations of traditional tools for beyond design basis external hazard PRA


By: P. Vaishanav n, A. Gupta n & S. Bodda n

author keywords: Probabilistic risk assessment; Beyond design basis accidents; Common cause failure; Bayesian network; Event tree; Fault tree; Logic tree; PRA
TL;DR: Two simple and a relatively more complex illustrative examples are used to show the limitation of these assumptions in the numerical quantification of risk for the case of BDB conditions and a Bayesian network based top-down algorithm is proposed as an alternative tool for accurate numerical quantifying of total risk in systems analysis.
