Work on the fabrieation of ceramic fuel elements by isostatic pressing was directed at improving the density of the hot isostatically pressed, fused UO/ sub 2/ compacts, and determining the changes in the structure of the cladding due to hot isostatic pressing. Attempts to prepare dense samples for thermal conductivity tests, using 92 M% UO/sub 2/-8 M% Y/sub 2/O/sub 3/ rather than 96 M% UO/sub 2/-4 M% Y/sub 2/O/sub 3/ as in previou s period, were unsuccessful. Attempts to standardize the thermal conductivity furnaces with three UO/sub 2/ samples are still unsuccessful. Work was continued on the determination of the behavior of stainless steel-clad, isostatically pressed oxide samples relative to that of standard, pelletized UO/sub 2/, under prolonged neutron irradiation. Work has started on the determination of the dimensional stability of U--Y alloys under neutron irradiation at high temperatures. (For preceding period see SCNC- 303.). (W.L.H.)
