Los Alamos National Laboratory
Advanced Reactor Fuel Cycles and Simulations
Dr. Holly Trellue, Los Alamos National Laboratory, is an expert in advanced reactor fuel cycles and simulations and is leading several nuclear energy and nonproliferation-related efforts. Dr. Trellue has performed neutronic and depletion simulations on numerous reactor systems over the past 28 years and is the Technical Area Lead for the DOE-NE Microreactor Program. She has significant experience working on reactor/critical experiment simulations, nuclear data, and nonproliferation topics related to reactors as well as nuclear fuel cycle analysis. She earned a PhD in nuclear engineering from the University of New Mexico in 2003 and is now also the leader of the Engineering Institute at LANL.
