Dr. Lin-wen Hu
Senior Research Scientist

Dr. Hu has over 20 years of experience in nuclear reactor design, safety analysis and applications. She currently directs NRL’s research and irradiation services division, which consists of reactor experiments, neutron activation and elemental analysis, neutron beam applications, and reactor physics groups. She is the Technical Lead at MITR as a partner facility of Idaho National Laboratory’s Nuclear Science User Facilities (NSUF) and engaged in the development of a wide range of nuclear applications including advanced nuclear fuel and materials irradiation tests, radioisotope production, licensing, and safety analysis of nuclear reactors. She is currently the Principal Investigator or co-Principal Investigator on several research projects including MITR LEU fuel conversion feasibility study; Fluoride salt-cooled High-temperature Reactor (FHR) design, modeling and safety analysis, fluoride salt and materials irradiation testing; and Transient Reactor Test Facility (TREAT) modeling and instrumentation design. Dr. Hu has authored or co-authored over 190 technical publications. She is an American Nuclear Society Fellow.
