Nicolas E. Stauff

Manager, Nuclear Applications and Economics Group

Nuclear Engineer in Reactor Physics and Nuclear Economics



Nicolas Stauff joined the Argonne National Laboratory in 2012 in the Nuclear Systems Analysis department within the Nuclear Science and Engineering Division. He has been contributing to a variety of projects in the fields of reactor physics, fuel cycle analyses, and economics assessment for advanced nuclear reactors. Dr. Nicolas Stauff leads the Nuclear Applications and Economics group that supports DOE-NE, ARPA-E and the nuclear industry in these fields. Dr. Nicolas Stauff leads research on the compatibility of nuclear technologies with variable grid demand for the US DOE System Analysis and Integration Campaign. He also leads the development of a user interface to Argonne’s advanced reactors analysis codes within the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program, and the user assessment of NEAMS codes capability to perform high-fidelity multiphysics simulations on micro-reactors. Finally, he is contributing to the development of advanced reactor designs in collaboration with industry (HolosGen, ARC LLC, Westinghouse, etc.).

Before joining Argonne, Dr. Nicolas Stauff performed research at the Massachusetts Institute of Technology (MIT), and at the French Atomic Energy Commission (CEA) on designing advanced fast neutron reactors with carbide fuel. He received his Ph.D. in nuclear engineering from the University of Paris XI and his M.S and B.S. in electrical engineering from the SUPELEC school in France.
