COLLECTION AND MEASUREMENT OF STABLE FISSION XENON IN SHEATH PUNCTURE EXPERIMENTS-METHOD AND RESULTS TO DATE
A method is described for collecting and analyzing the stable isotopes of fission product Xe contained beneath the sheath of a UO/sub 2/ fuel element after irradiation in the reactor. The element is placed in a specially designed chamber in the hot-cell, the chamber evacuated, and a hole made in the sheath of the element by means of a drill operating through a vacuum-tight seal. Helium is then flowed through the chamber and the rare-gas fission products trapped out of the He flow on a charcoal trap cooled with dry-ice in acetone. The fission Xe is purified, measured volumetrically and examined in a mass spectrometer. The data obtained with fuel elements from three rod assemblies are tabulated and the results discussed. (auth)
