Biography

Since joining the Pacific Northwest National Laboratory in 1992, Dr. Senor has worked in a variety of nuclear-related materials science and technology areas. His work has focused on irradiation behavior evaluation, physical, mechanical and thermal property measurement, and manufacturing development of conventional and advanced nuclear materials, including SiC for fission and fusion reactor structural applications, tritium-producing burnable absorber rods for use in commercial PWRs, burnable-absorber-containing fuel channels for use in commercial BWRs, advanced spherical cermet fuel forms for use in LWRs, U-Mo fuels for use in LWRs and high-performance research reactors, and materials for high-power proton accelerator targets and windows. He has participated in various aspects of irradiation testing and post-irradiation examination of structural materials and fuels irradiation experiments in ATR, MITR, EBR-II, JOYO, FFTF, HFIR, and HFR Petten. Dr. Senor is presently the lead experimenter for a series of materials irradiation tests in ATR investigating irradiation effects on components used in tritium-producing burnable absorber rods. He has authored or co-authored over 130 journal articles, presentations, and technical reports in the open literature and holds two US patents.
