Pebble-bed pebble motion: Simulation and Applications

Abstract

Thanks are due to many people who have provided information, comments and insight. I apologize in advance for anyone that I have left out. Thanks go to Javier Ortensi for the encouragement and discussion as he figured out how use the earthquake data and I figured out how to generate it and for the assistance with the graphite dust portion. At INL the following people assisted: Rob Bratton and Will Windes with the graphite literature review, Brian Boer with discussion and German translation, Hongbin Zhang with encouragement and Chinese translation, Hans Gougar for the encouragement and ideas, and Suzette J. Payne for providing me with the earthquake motion data. The following PBMR (South Africa) employees provided valuable help locating graphite literature and data: Frederik Reitsma, Pieter Goede, and Alastair Ramlakan. The Juelich (Germany) people-Peter Pohl, Johannes Fachinger, and Werner von Lensa-provided valuable assistance with understanding AVR. Thanks to Professor Mary Dunzik-Gougar for introducing me to many of these people, as well as encouragement and feedback on this PhD and participating as co-chair on the dissertation committee. Thanks to the other members of my committee, Dr. Michael Lineberry, Dr. Steve C. Chiu and Dr. Steve Shropshire, for providing valuable feedback on the dissertation. Thanks to Gannon Johnson for pointing out that length needed to be tallied separately from the length times force tally for the wear calculation (this allowed the vibration issue to be found). Thanks to Professor Jan Leen Kloosterman of the Delft University of Technology for providing me the PEBDAN program used for calculating Dancoff factors. Thanks also to Akira Tokuhiro, Donald Carlson, and Luo Xiaowei for various suggestions. Thanks to Elizabeth Cogliati for proofreading a previous version of this report.
