AN EXTRAPOLATED EQUATION OF STATE FOR XENON FOR USE IN FUEL SWELLING CALCULATIONS

An extrapolation is made of the existing argon equation of state to higher pressures and temperatures. Because there is good experimental evidence that the theorem of corresponding states is obeyed for argon and xenon over the range of existing experimental measurements the extrapolated argon equation may be used for xenon with suitable scaling. Examples are given of the use of the new xenon equation of state in the calculation of gas contents of bubbles and uranium carbide swelling and compared with similar calculations using the modified van der Waals' law showing how the latter underestimates the gas content of bubbles and overestimates gas swelling. © 1969.
