Dr. Clarno is a tenured Associate Professor in the Nuclear and Radiation Engineering program at the University of Texas at Austin with a research focus on computational nuclear energy, including algorithm development for radiation transport and reactor multiphysics. Dr. Clarno worked 15 years at Oak Ridge National Laboratory (ORNL), and was also assistant professor at the University of Tennessee-Knoxville as joint faculty member in nuclear engineering. He has led national, multi-institutional high-performance computing (HPC) research programs, including the Consortium for Advanced Simulation of Light Water Reactors (CASL) as Interim Director; the CASL Physics Integration (PHI) Focus Area; modernization of the SCALE nuclear analysis software; development of the Advanced Multi-Physics (AMP) fuel performance code; and a portfolio of ORNL laboratory-directed strategic research projects. As a technical contributor at ORNL, Dr. Clarno has developed high-performance computing software, researched new algorithms for SCALE, and performed analyses of nuclear reactors for a diverse set of US Nuclear Regulatory Commission (NRC) and DOE projects.
Dr. Clarno’s primary research areas include: Multiphysics coupling methods for advanced simulation of nuclear reactors to integrate analyses and improve accuracy; Multiscale neutronics, fuel performance, and thermal-hydraulics to enable high resolution analyses in coupled physics applications; Design, optimization, and analysis of advanced commercial and test reactor concepts; Integration of software to optimize advanced manufacturing of nuclear technologies; and Propagation of uncertainties through multiphysics applications to optimize experiments.
