Abstract
A relatively simple comparative method for measuring fission product escape from solid fuel elements has been devised. Although the method has limitations, it serves to "screen" various materials as to their relative ability to retain volatile or gaseous fission products. The Xe, I and Te which were collected from the ceramic specimens employed in this study are probably representative of the fission products which are most likely to escape. On this premise it is shown that between 900 and 1000 deg C about 0.001% to 6.01% of the gaseous or volatile fission products are likely to escape from nonporous ceramics. In addition to the above fission products, others collected from tests made on loose UO/sub 2/ powder "standards" included Mo, Ba, Zr, Sr, and rare earths. (auth)
