Matteo Bucci joined the NSE faculty as an assistant professor in the fall of 2016. He received his MSc (2005) and PhD (2009) in Nuclear Engineering from University of Pisa, Italy. His research is focused in three main areas: diagnostics for advanced heat transfer investigations, heat transfer nanoengineering innovations to improve the safety and economic competitiveness of nuclear reactors, and integration of advanced diagnostics, simulations and machine learning tools to monitor the health of nuclear systems. Bucci is also a member of the Center for Advanced Nuclear Energy Systems (CANES), one of the MIT’s eight Low-Carbon Energy Centers.

Development of advanced diagnostic tools and techniques

We develop advanced diagnostics to study the physics of two-phase flow and heat transfer phenomena. The research includes the development of advanced Infra-Red (IR) thermography techniques combined with High-Speed Video, the development of new materials and coatings, and the characterization of their physical properties. The modelling of multi-scale, multi-physics phenomena, i.e. combining heat transfer and optics, is key to developing and optimizing these diagnostics.

Boiling heat transfer

We design and perform experiments to shed light on the physics of boiling heat transfer and obtain detailed experimental data to inform and validate computational models used for the design and the safety analysis of nuclear reactors. To achieve a superior understanding of these phenomena, we develop advanced diagnostic tools and techniques. Measured quantities include but are not limited to: time dependent temperature, heat flux and phase distributions on the boiling surface, onset of nucleate boiling temperature and heat flux in both steady and transient conditions, bubble departure diameter and frequency, growth and wait times, nucleation site density, dry area fraction, contact line density, and heat flux partitioning. Leveraging the improved understanding achieved by these experiments, analytical models are developed to provide a faithful representation of boiling heat transfer phenomena and surface effects on the nuclear reactor fuel.

Nanotechnologies for advanced heat transfer performance

We use micro and nanotechnologies to engineer the surfaces of nuclear reactors at the micro and the nano scale. Micro and nano technologies can be used to create super-hydrophilic, super-hydrophobic, or even super-biphilic surfaces that can be optimized to improve the efficiency of the heat transfer mechanisms in every component of the nuclear power plant, leading to potentially very significant power uprates and also reduction of both direct and indirect capital costs.

Integration of sensors, simulations and machine learning tools for advanced health monitoring of complex systems

We are developing a new approach to monitor the health of nuclear systems and components. This approach integrates advanced diagnostics and simulations with machine learning tools, in order to improve situational awareness, e.g. reducing uncertainties on the actual operating conditions, to detect and diagnose faults, as well as to anticipate failures in nuclear power plants.
