Tanju Sofu

Program Manager, Modeling, Simulation and Licensing

Tanju Sofu is the deputy national technical director of DOE’s Nuclear Energy Advanced Modeling & Simulation (NEAMS) program.


Tanju Sofu is a senior leadership team member of DOE’s Nuclear Energy Advanced Modeling & Simulation (NEAMS) program. His responsibilities include technical leadership and programmatic guidance for multi-laboratory efforts on development of advanced modeling and simulation methods/tools for engineering design, safety analyses, and risk assessments to support deployment of innovative nuclear reactor concepts. He also coordinates the multi-laboratory contributions to the methods, modeling and validation activities under the Fast Reactor Campaign of DOE’s Advanced Reactor Technologies (ART) program, and manages advanced reactor licensing activities at Argonne’s Nuclear Science and Engineering Division with the Nuclear Regulatory Commission.

Tanju Sofu joined Argonne in 1992 as a postdoctoral appointee after receiving his Ph.D. in nuclear engineering from University of Tennessee in Knoxville. During his tenure at Argonne, he contributed to numerous projects involving large-scale computational physics and fluid dynamics simulations on high-performance computing platforms for design optimizations, model validations, and safety analyses. His more recent technical work focused on development of codes and models for engineering system analyses involving multidimensional, multi-physics phenomena. He serves as the co-chair of OECD-Nuclear Energy Agency’s Generation-IV International Forum (GIF) Risk and Safety Working Group and the Safety Design Criteria Task Force.
