Paolo Vinai

Docent at Chalmers, Physics, Subatomic and Plasma Physics

My research focus is modeling and simulations of nuclear reactors. I work with computational models for reactor physics, fluid dynamics, and heat transfer. I am also interested in nuclear reactor safety, validation of nuclear codes, and sensitivity and uncertainty methods for reactor calculations. The goal is to develop high-fidelity simulation tools and more accurate methodologies for the analysis of nuclear reactors under operational and accidental conditions.
