The Consortium for Advanced Simulation of Light Water Reactors (CASL) brings together an exceptionally capable team that will apply existing modeling and simulation (M&S) capabilities and develop advanced capabilities to create a usable environment for predictive simulation of light water reactors (LWRs). This environment, designated the Virtual Reactor (VR), will:
In this seminar I will overview the CASL vision, mission, objectives, and technical plan and give some preliminary results achieved during our first year of execution.
Douglas B. Kothe (Doug) graduated Summa Cum Laude in 1983 with a Bachelor in Science in Chemical Engineering from the University of Missouri - Columbia, followed by his Masters in Science and Doctor of Philosophy (PhD) in Nuclear Engineering at Purdue University in 1986 and 1987, respectively. He conducted his PhD research at Los Alamos National Laboratory (LANL) from 1985-1987 as a Graduate Research Assistant, where he developed the models and algorithms for a particle-in-cell application designed to simulate the hydrodynamically unstable implosion of inertial confinement fusion targets. After a brief period as a nuclear weapons designer where he participated in the underground testing program at the Lawrence Livermore National Laboratory, he returned to LANL in 1988 as a Technical Staff Member in Fluid Dynamics Group T-3 for the next nine years, where he helped develop three computational fluid dynamics (CFD) applications know as Ripple, Pagosa, and CFDLIB. After a three-year stay in LANL Structure/Relations Group MST-8, Doug became in 2000 the Group Leader of the LANL Continuum Dynamics Group CCS-2 and Program Manager of the Computational Sciences Program Element within the DOE Advanced Simulation and Computing (ASC) Program through 2004. From 2004-2006, Doug took on the role of Deputy Division Leader of the Computer and Computational Sciences (CCS) Division, then Deputy Project Director of the $200M per year LANL ASC Program.
In January 2006, Doug joined Oak Ridge National Laboratory (ORNL) as Director of Science in the National Center of Computational Sciences, a role he served in for approximately four and a half years. In May 2010, Doug led a multi-institutional, multi-disciplinary team known as "CASL" (Consortium for Advanced Simulation of Light Water Reactors; www.casl.gov) in winning a $122M, five-year award from the U.S. Department of Energy for its first Energy Innovation Hub. As a result of this award, Doug is now Director of CASL and the CASL Division Director at ORNL. CASL was called out (indirectly) by the President in his Jan 2011 State of the Union Address: "At Oak Ridge National Laboratory, they're using supercomputers to get a lot more power out of our nuclear facilities".
Doug's research interests and expertise is focused on development of physical models and numerical algorithms for the simulation of a wide variety of physical processes in the presence of incompressible and compressible fluid flow. A notable contribution is his development of methods for flows possessing interfaces having surface tension, especially free surfaces. Another has been the development and application of an advanced casting/welding simulation tool (known as "Truchas") for the U.S. Department of Energy Complex. Doug has authored over 60 refereed and invited publications and written over one-half million lines of scientific source code.
Doug and his wife AdriAnne have three sons: Brett (26), a 1st-year medical resident in Pediatrics at Saint Louis University; Brock (24), a Defensive Assistant in the University of Tennessee (UT) Football Program; and Matthew (22), a recent Pre-Law graduate from the University of Tennessee. In addition to spending his time with his wife and family, Doug's hobbies include boating, water skiing, jogging, golf, music (trumpet and bell choir), history, and St. Louis Cardinals baseball.Workshop Program
