Signed: __________________________________________________________ Eunjung Lim, Ph.D. Member of dissertation committee ACKNOWLEDGMENTS In many respects, this dissertation is the culmination of several decades of the support, encouragement, and guidance of a plethora of individuals who (knowingly or unknowingly) invested their time and energy into me. It is impossible to give proper attribution to every single person, and in most cases a simple thank you is insufficient. However, the lessons I have learned in my education are culminated in this product, and I do wish to acknowledge those that have shaped my journey. I am extremely grateful for the tireless service and support of my committee members. The support my chair, Dr. Janet Johnson, has been unending—quite literally, as my project as extended into her retirement—and I have immense appreciation for her diligence to see this project through to completion. Without her unending support, passion for research, and dedication to helping her students, my years of graduate study would have been very different. Dr. Ben Bagozzi has also been instrumental to the success of this dissertation project, especially regarding the methods sections but also including many rounds of thorough comments on several drafts of this dissertation. I am also thankful for Dr. Daniel Kinderman’s thoughtful questions and advice on a “realistic” approach to graduate studies, surviving the dissertation, and post-completion job prospects. Finally, I am very grateful to Dr. Eunjung Lim for her willingness to serve as my external member, even from the far side of the world and extending across many time zones. I have been very privileged to have such an excellent committee for my dissertation. iv As the undertaking of a dissertation is not solely an intellectual project, but also an emotional one, there are many that have contributed to this endeavor. I have been very dearly supported by many other academic friends and colleagues, both at the University of Delaware and at other institutions who have given me an encouraging word, a much needed laugh, or a caring shoulder upon which to cry. Special acknowledgement goes to those who have especially fostered me through crucial moments of needed reassurance, including the Drs. Huntleigh, Paul Sulzer, Dr. Matthew Weinert, Lynn Corbett, and Dr. Sophie Le Blanc. More specific attribution goes to the following individuals: I have JDawg to thank for initially provoking my interest in nuclear energy and the aftermath of Fukushima through a joint humorously named project; My “best” roommate Zofia Maka has indefatigably shown me love and determination throughout my entire PhD experience, and I am so enormously grateful for all the times we together monitored the parking situation at Panera, searched for the best happy hour, survived the shower on Alexandria Drive, and danced our stress away at Zumba; I have been incredibly lucky to have a fierce friend and editor in Morgan Figa, who tirelessly (or if she did tire, she did not let me know) and painstakingly reviewed every single line of this dissertation. Those in my family have played a crucial role, both in my overall education and this direct product of it. My parents, who homeschooled me, enabled me to develop a love of learning at a young age. Their patience and prayers did not go unnoticed, even when they (and I at certain points) had no idea what this dissertation was about. My seven siblings have often provided a much needed refuge from the trials of the academy. I do not know what I have done to be placed on this earth with v such a dear sister, Dr. Amanda Sanchez, who knew what the doctoral process was and just how to encourage me through it. Finally, my partner in life and in love, Richard. Your intellectual and emotional investment in this product is second only to my own. I know with absolute certainty that I would not have accomplished this degree without your support, whether it was using your big brain to troubleshoot matters of quantitative modeling or using your big heart to hold me and my tears of frustration at 3am. Words cannot express how much you have enriched my life. Your unwavering support made even the hardest days brighter. vi TABLE OF CONTENTS LIST OF TABLES ........................................................................................................ xi LIST OF FIGURES ..................................................................................................... xiii ABSTRACT ................................................................................................................ xiv Chapter 1 INTRODUCTION .............................................................................................. 1 1.1 Background on the Fukushima Accident ............................................... 3 1.2 Global Reaction to Fukushima. .............................................................. 6 1.3 Why Care About Nuclear Accidents? .................................................. 10 1.4 The Argument in Brief. ........................................................................ 20 1.5 Overview of Dissertation Project. ........................................................ 23 2 THEORETICAL CONTRIBUTIONS AND LITERATURE REVIEW ........ 26 2.1 The Study of Nuclear Energy ............................................................... 27 2.1.1 Comparative Study and Fukushima ................................................ 27 2.1.2 Overview of Nuclear Literature ...................................................... 29 2.2 Understanding Disasters and Constructing a Disaster Event ............... 32 2.2.1 Uniqueness of Nuclear Disasters ................................................... 32 2.2.2 Studying Disasters. ......................................................................... 33 2.2.3 Disasters as Social and Political Catalysts. ................................... 34 2.2.4 Natural vs. Technological Disaster Studies ................................... 36 2.3 Socially Constructed Factors ................................................................ 39 2.3.1 Policy Making. ................................................................................ 41 2.3.2 Perception of Risk. .......................................................................... 43 2.4 Public Policy: Understanding Change After Critical Events ............... 49 2.4.1 Public Policy Literature ................................................................. 49 2.4.2 Agenda Setting ................................................................................ 52 2.4.3 Change After Crisis ........................................................................ 54 vii 2.5 Explanations for Change in Nuclear Policy ......................................... 55 2.5.1 Factors ............................................................................................ 56 2.5.2 Rationalist Decision Making in Nuclear Policy. ............................ 65 2.6 Theoretical Contribution ...................................................................... 66 2.6.1 Focusing Events. ............................................................................. 67 2.6.2 Social Construction. ....................................................................... 69 2.6.3 Expectations. .................................................................................

  • Dimensions of Disaster During Hurricane Katrina: Landscape
    Dimensions of Disaster During Hurricane Katrina: Landscape, Levees, and the Least Fortunate Sarah McKinnell Geography Department – Fall 2012 Professor William Travis – Head Advsior – Geography Department Professor Stefan Leyk – Geography Department Professor Mary Kraus – Geology Department Abstract: In 2005 Hurricane Katrina made landfall in Southeastern Louisiana as a powerful Category Three hurricane. The hurricane protection systems in place for the city of New Orleans and surrounding parishes were overwhelmed sending billions of gallons of water into local communities. This atypical flood volume inundated 80% of New Orleans, impeding rescue efforts and devastating infrastructure and emergency resources. Over 1,500 lives were lost and an estimated 125 billion US dollars were spent on emergency response, recovery, and reconstruction. Hurricane Katrina is the worst disaster in the United States in over a century. This paper analyzes why Hurricane Katrina was such a catastrophe. Three major reasons for disaster are identified: construction of piecemeal levee systems, wetland loss, and social vulnerabilities. Throughout the history of southeastern Louisiana’s settlement, the natural hydrography was manipulated in order to protect life and property from flooding; a fragmented levee system was constructed based on underestimated storm risk resulting in the hurricane protection system that failed during Hurricane Katrina. Similarly, increased residential development, canal building, and natural land subsidence processes have degraded natural wetlands which function as protective barriers from storm surges. The population of New Orleans exhibited high social vulnerabilities, as many Katrina victims lacked the tools, knowledge, and capabilities necessary to evacuate in a timely manner or to exercise other self-protective measures. These three elements—fragmented levee systems, wetland degradation, and high social vulnerabilities—exacerbate the level of vulnerability of property and people along the Gulf Coast.

  • Space Shuttle Case Studies: Challenger and Columbia
    Paper ID #8419 Space Shuttle Case Studies: Challenger and Columbia Dr. Scott L Post, Bradley University Scott Post received his Ph.D. in Mechanical Engineering from Purdue University. He is currently an Asso- ciate Professor at Bradley University in Peoria, IL. He has previously worked as an Assistant Professor at Michigan Technological University. He has also been a summer Faculty Fellow at NASA Dryden Flight Research Center, and a Visiting Erskine Fellow at the University of Canterbury in Christchurch, New Zealand. c American Society for Engineering Education, 2014 Space Shuttle Case Studies: Challenger and Columbia Abstract The two Space Shuttle tragedies, Challenger and Columbia, have led to many papers on case studies on engineering ethics. The Challenger disaster in particular is often discussed due to the infamous teleconference that took place the night before the launch in which some engineers tried to postpone the launch. However, the space shuttle program itself is worthy of study as it relates to the engineering design process, and the details of the Challenger and Columbia disasters are worthy of discussion as they relate to a variety of sub-disciplines, including material science, thermodynamics, fluid mechanics, and heat transfer. This paper summarizes the major technical findings of the Rogers Commission and the Columbia Accident Investigation Board (CAIB). An overview of the history of the space shuttle program, going back to the end of the Apollo program, is presented, including some of the design compromises that were made in order to get political support for the space shuttle program. A detailed bibliography is given that will aid instructors in finding additional material they can tailor to their particular class needs.

  • Introduction to Fracture Mechanics
    Introduction to Fracture Mechanics David Roylance Department of Materials Science and Engineering Massachusetts Institute of Technology Cambridge, MA 02139 June 14, 2001 Introduction In 1983, the National Bureau of Standards (now the National Institute for Science and Tech- nology) and Battelle Memorial Institute1 estimated the costs for failure due to fracture to be $119 billion per year in 1982 dollars. The dollars are important, but the cost of many failures in human life and injury is infinitely more so. Failures have occurred for many reasons, including uncertainties in the loading or envi- ronment, defects in the materials, inadequacies in design, and deficiencies in construction or maintenance. Design against fracture has a technology of its own, and this is a very active area of current research. This module will provide an introduction to an important aspect of this field, since without an understanding of fracture the methods in stress analysis discussed previously would be of little use. We will focus on fractures due to simple tensile overstress, but the designer is cautioned again about the need to consider absolutely as many factors as possible that might lead to failure, especially when life is at risk. The Module on the Dislocation Basis of Yield (Module 21) shows how the strength of struc- tural metals – particularly steel – can be increased to very high levels by manipulating the microstructure so as to inhibit dislocation motion. Unfortunately, this renders the material in- creasingly brittle, so that cracks can formand propagate catastrophically with very little warn- ing. An unfortunate number of engineering disasters are related directly to this phenomenon, and engineers involved in structural design must be aware of the procedures now available to safeguard against brittle fracture.
