Investigation of the Reactions Between Uranium Dioxide, Thorium Dioxide and Uranium Tetrafloride in the Liquid and Vapor Phase; A Project presented to the Department of Nuclear Engineering of the University of Florida in partial fulfillment of the Requirements for the Degree of Master of Engineering
Gainesville, FL: University of Florida, 1990. Presumed First Edition, First printing thus. Comb binding. vi, 75 pages. Clear plastic sheet in front of thesis cover. List of Figures. Abstract. Introduction. Experimental Description. Results. Conclusions, Appendices, and References. This work involved a literature survey, both theoretical and experimental methods and a review of current work. The experiment involved apparatus, procedure, sample description and post exposure analysis. The primary conclusion was that neither UO2 nor ThOs were suitable for use as structural or lining materials in exposure to pure UF4 in either the liquid or gas phase. However the results did prove the applicability of the phase diagram produced by Fonteneau and Lucas to the liquid phase reactions of these compounds, as well as proving the assumption that at the temperatures of interest in this study, corrosive reactions would proceed to equilibrium so rapidly as to make reaction kinetics relatively unimportant. Robert Hanrahan (1965-2022) Ph.D., JD, has worked on nuclear weapons science and engineering since 1991, first at Los Alamos National Laboratory and since 2007 as a federal employee of the National Nuclear Security Administration (NNSA.) He holds Ph.D. is in Materials Science from the University of Florida and a JD from George Mason School of Law. He is admitted to the Maryland Bar. Robert J. Hanrahan, Jr. earned bachelor’s and master’s degrees in nuclear engineering and a doctorate in materials science engineering with a focus on metallurgy. Upon graduating UF, he worked for many years as a researcher at the Los Alamos National Laboratory in New Mexico, and then moved to the Washington, DC, area to take a position at the Nuclear National Security Administration (NNSA) at the U.S. Department of Energy (USDOE). He completed his career with responsibilities as Chief Science Advisor at the NNSA USDOE, providing input on much of our nation’s most sensitive work on nuclear security. He had among the highest security clearances; acted as a liaison to The JASONs, a prestigious and elite group of scientists; and always took his responsibilities extremely seriously. Among his many professional accomplishments, he co-edited a six-volume text book on plutonium and published 75 peer-reviewed articles and numerous magazine stories. In 2010, he completed a law degree at George Mason University and was later admitted to the Maryland Bar. Condition: Good.
