  • WELCOME! At U.C. Berkeley, nuclear engineers are leading in research that will enable long-term sustainable and economic production of nuclear energy from fission and fusion; provide for responsible recycling and disposal of nuclear wastes; develop advanced, radiation tolerant materials for high-temperature applications; assure security by detecting illicit transfers of nuclear materials; and advance applications of nuclear methods for medical imaging and therapy.


  • One of Prof. Per Peterson's research foci on nuclear thermal hydraulics is Mark 1 Pebble-Bed FHR (Mk1 PB-FHR). The pre-conceptual design is the latest in a series of studies to explore potential designs for fluoride salt cooled, high temperature reactors. 


  • Research Spotlight: Prof. Peter Hosemann's research on nuclear materials and chemistry focuses on applying experimental materials science techniques to understanding the effects of radiation degradation on structural nuclear components (fission, fusion, spallation, etc.).


  • NEWS HIGHLIGHT: The Radwatch Air Monitoring team has put together a unique system that serves high-resolution gamma-ray data hourly to monitor naturally occurring, airborne radioactivity. Weather data are also served to provide insight to correlations that exist in the transport of these radionuclides.
