Steven A Williams

Nuclear Mechanical Engineer

As a Systems Engineer for the Research Reactors Division in the Neutron Sciences Directorate at ORNL, Mr. Williams is responsible for the safe, reliable, and efficient operation of the High Flux Isotope Reactor (HFIR).  This 85MW reactor is the highest flux reactor-based source of neutrons for research in the United States, and it provides one of the highest steady-state neutron fluxes of any research reactor in the world, enabling world-class capabilities for neutron scattering, isotope production, materials irradiation, neutron activation analysis, and nuclear physics.

Mr. Williams came to ORNL in May of 2020 to join the High Flux Isotope Reactor (HFIR) Systems Engineering group as a Mechanical Engineer. Currently, Mr. Williams is assigned to support the HFIR Secondary Coolant System, Special Building Hot Exhaust, Steam Distribution, and various other HFIR systems. Mr. Williams is also supporting procurement and fabrication of new Horizontal Beam Tubes for the upcoming HFIR Permanent Beryllium Reflector replacement.

Mr. Williams earned a B.S. in Mechanical Engineering from the University of Tennessee, Knoxville in 2009. After graduating he worked at the Watts Bar Unit 2 construction project as a mechanical planner and field engineer. From 2011-2014 he was a mechanical procurement engineer at Sequoyah Nuclear plant. Mr. Williams then worked as a systems engineer at Sequoyah Nuclear Plant where he was responsible for the Auxiliary Feedwater and Reactor Coolant Systems. He became a licensed Professional Engineer in control systems in the state of Tennessee in 2021.
