MANUFACTURE OF THE ThO$sub 2$-UO$sub 2$ CERAMIC FUEL PELLETS FOR BORAX-IV
Preliminary investigation indicated that it was possible to prepare thoria-urania solid solutions by sintering in air a mixture of ThO/sub 2/ and U/ sub 3/O.sub 8/. The U/sub 3/O/sub 8/ on heatin g in air was found to disassociate, and when heated with ThO/sub 2/, the resultant body was essentially a ThO/sub 2/-UO/sub 2/ solid solution. The methods used in preparing and granulating the ThO/sub 2/ and U/sub 3/O/sub 8/ for the BORAX-IV loading are discussed in detail. This material was dry pressed using pressures from 13,000 to 15,000 psi. The pressed pellets were loaded into alumina crucibles and fired to a peak temperature of 1700 deg C to 1750 deg C. The fired ware was found to have an average ap parent density of 9.8 g/cc. The pellets were loaded into Al1 wt.% Ni tube plates and the annulus between the pellet and the tube was filled with lead. After closing the open end of the tube plates, the plates were spot welded into a subassembly. (auth)
