STABILITY OF UO$sub 2$-NaK SLURRIES. Final Report
The UOsub 2/-NaK system was studied with special reference to the wetting of UO/dub 2/ by NaK and the effect of temperature on the viscosity of the UO/dub 2/-NaK slurry. It was found that UO/sub 2/ powder of approximately 1 micron average particle diameter was wetted by NaK at approximately 400 un. Concent 85% C. No evidence of dewetting or flocculation was noted at temperatures up to 600 un. Concent 85% C, although it was not proved conclusively flocculation does not occur at the higher temperatures. Some evidence of reaction between UO/sub 2/ and NaK or impurities in the NaK was found. This was evidenced by a change in the color of the UO/sub 2/ after exposure to NaK at 600 un. Concent 85% C. The UO/sub 3/ -water system was studied with regard to application to a reactor core consisting of layers of granulated UO/sub 3/ cooled by water. Beds of UO/sub 3/, covered with water, were heated to 300 un. Concent 85% F. Resistance to the flow of water was measured. Heating of the beds in contact with water produced a slight change in particle size distribution but the change in flow resistance was negligible. (P.C.H.)
