Jordi Roglans-Ribas

Division Director


Jordi Roglans-Ribas is the Director of Argonne’s Nuclear Science and Engineering (NSE) Division. He is a senior nuclear engineer and has been with Argonne since 1987. He is responsible for overseeing the NSE division’s operations and providing programmatic leadership and strategic planning.

The NSE division is dedicated to nuclear technology development including advanced reactors and fuel cycles, materials research, nonproliferation and national security programs. The Division’s extensive capabilities in modeling and simulation are applied in the development of diverse engineering systems and the optimization of their performance.

Previously, Dr. Roglans-Ribas was the Argonne Program Director for the National Nuclear Security Administration’s Material Management and Minimization-Reactor Conversion program, a program intended to minimize, and to the extent possible eliminate, the use of highly-enriched uranium in civil applications by converting research and test reactors to the use of low-enriched uranium (LEU) fuel and targets for the production of medical isotopes.

Dr. Roglans-Ribas’ previous assignments include Associate Director of Argonne’s Advanced Fuel Cycle Initiative Program, Technical Director of the International Expert Group for the development of assessment methodologies for proliferation resistance and physical protection of Generation IV nuclear energy systems, co chair of the Evaluation Methodology Group during the Generation IV nuclear energy systems Technology Roadmap, and US system integration manager and co chair of the Generation IV International Forum Steering Committee for the Sodium-Cooled Fast Reactor (SFR).

Dr. Roglans-Ribas also worked as project manager in the Plant Safety Evaluation element of the US Department of Energy’s International Nuclear Safety Program, leading projects in safety analyses and computational tool validation for Russian-designed nuclear power plants, as well as analysis of SFRs and associated facilities. He earned his PhD from Iowa State University.
