Abstract
A method for determining the pressure versus internal energy coordinates of the liquid-vapor saturation curve is applied to the study of UO/sub 2/. The experimental details and results of an initial series of tests are described. A comparison of the measurement results to models of the UO/sub 2/ equation of state illustrates the role of the heat capacity in describing the P--E characteristics of the state surface. A discussion of the available heat capacity information suggests that additional modeling and measurements of the heat capacity may be needed to give a complete temperature and energy dependent state surface description. Because of these modeling uncertainties, a method of thermodynamically describing the P(V, E) state surface entirely through the use of dynamic vapor measurements is given. Such a model satisfies transient thermomechanical analysis requirements. Next the effect of the state surface on one type of core disruptive reactor analysis is examined. And finally, the property determinations and models for UO/sub 2/ are reviewed with requirements for future work being outlined.Keywords
