El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

The nuclear industry, as highlighted by both the U.S. Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE), has yet to fully harness the potential of recent advancements in AI/ML techniques. In this context, Digital Twin (DT) technology is poised to play a pivotal role in facilitating risk-informed decision-making. The NRC's "FY2021-23 Planned Research Activities" and "NRC Future Focused Research" identify "Methodology and Evaluation Tools for Digital Twin Applications" as a top-priority strategic area. However, the implementation of DT in nuclear systems poses significant challenges that need to be addressed. These challenges encompass various aspects, including: (a) Incorporating trustworthy data analytics algorithms, (b) Dealing with noisy or erroneous data and addressing data unavailability, (c) Quantifying uncertainties associated with DT, (d) Ensuring robust optimization techniques, and (e) Developing update modules in DT through the resolution of "On-the-fly Inverse Problems." In this panel session, we will explore the enabling technologies and components required to establish DT in the nuclear industry. Our discussion will delve into the solutions for tackling the aforementioned challenges and unlocking the potential benefits of DT for nuclear systems.
