Aaron M Graham

R&D Staff Member

Dr. Aaron M. Graham is an R&D staff member in the Power Reactor Modeling group at Oak Ridge National Laboratory (ORNL).  He received his B.S.E. in Nuclear Engineering from the University of Michigan in 2013.  He received his Ph.D. in Nuclear Engineering, Radiological Sciences, and Scientific Computing in 2017.  His graduate research focused on advanced techniques for addressing material heterogeneities in direct whole-core neutron transport calculations, namely planar synthesis methods.

At ORNL, Aaron has focused on multiphysics modeling and simulation, first as part of the Consortium for Advanced Simulation of Light Water Reactors and more recently as part of the Nuclear Energy Advanced Modeling and Simulation Hub and related reactor analysis projects.  He serves as the Technical Lead and Software Integrator for the Virtual Environment for Reactor Applications (VERA) and as the Code Lead for the MPACT neutron transport code (which serves as a driver for the VERA multiphysics calculations).  This role includes overseeing all development of VERA for Light Water Reactor analysis, including Pressurized Water Reactors, Boiling Water Reactors, and Small Modular Reactors.

Additionally, Aaron currently acts as the Code Lead for the Mole code, a multi-phase, multi-species transport code for Molten Salt Reactor analysis.  This includes development and implementation of chemistry models important to modeling molten salts and coupling these molten salt specific phenomena to other reactor phenomena, including neutron transport, isotopic transmutation, thermal hydraulics, and system component corrosion.
