To understand the potential of intelligent confirmatory tools, the U.S. Nuclear Regulatory Committee (NRC) initiated a future-focused research project to assess the regulatory viability of machine learning (ML) and artificial intelligence (AI)-driven Digital Twins (DTs) for nuclear power applications. Advanced accident tolerant fuel (ATF) is one of...

... order to demonstrate the uncertainty quantification method and sensitivity analysis to the BISON code, a model with simple geometry composed of nuclear fuel and cladding material properties is used. Fig. 1 represents the geometry, and the geometric design parameters are listed in Table 1. In this demonstration, uncertain input variables were room temperature values of thermal conductivity and mass density of UO 2 fuel and cladding as listed in Table 2. All input variables are assumed to follow a normal distribution with a 5% coefficient ...

The design and operation of systems are conventionally viewed as a sequential decision-making process that is informed by data from physical experiments and simulations. However, the integration of these high-dimensional and heterogeneous data sources requires the consideration of the impact of a decision on a system’s remaining life cycle. Consequ...
