PREPARATION OF UO$sub 2$ PELLETS CONTAINING FLUORIDE

Technical Report ·
OSTI ID:4036862
An irradiation experiment is being conducted to test whether the presence of fluoride in UO/sub 2/ causes catastrophic failure of UO/sub 2/ fuel elements sheather in Zircaloy-2. The experiments performed to determine a method of retaining fluoride in high concentrations (approximately 600 ppm F/sup -/, U basis) in sintered UO/sub 2/ pellets are described. The addition of the fluoride as calcium fluoride and the use of a modified sintering cycle was found to give satisfactory fluoride retention. (auth)
