Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.
2020 ANS Virtual Winter Meeting Plenary Session Speaker
Douglas B. Kothe (Doug) has thirty-five years of experience in conducting and leading applied R&D in computational science applications designed to simulate complex physical phenomena in the energy, defense, and manufacturing sectors. Doug is currently the Director of the U.S. Department of Energy (DOE) Exascale Computing Project. Prior to that, he was Deputy Associate Laboratory Director of the Computing and Computational Sciences Directorate at Oak Ridge National Laboratory (ORNL). Other positions for Doug at ORNL, where he has been since 2006, include Director of Science at the National Center for Computational Sciences (2006-2010) and Director of the Consortium for Advanced Simulation of Light Water Reactors (CASL), DOE’s first Energy Innovation Hub (2010-2015). In leading the CASL Hub, Doug drove the creation, application, and deployment of an innovative Virtual Environment for Reactor Applications (2016 R&D winner), which offered a technology step change for the US nuclear energy industry.
Before coming to ORNL, Doug spent 20 years at Los Alamos National Laboratory, where he held a number of technical and line and program management positions, with a common theme being the development and application of modeling and simulation technologies targeting multi-physics phenomena characterized by the presence of compressible or incompressible interfacial fluid flow, where his field-changing accomplishments are known internationally. Doug also spent one year at Lawrence Livermore National Laboratory in the late 1980s as a physicist in defense sciences.
Doug holds a Bachelor in Science in Chemical Engineering from the University of Missouri – Columbia (1983) and a Masters in Science (1986) and Doctor of Philosophy (1987) in Nuclear Engineering from Purdue University.
