Experimental results show that loaded bellows steel canisters, evacuated and sealed, can be cold-isostatically pressed before HIP from an initial density of 26 to 46% theoretical. Calcined powders are hygroscopic and may require degassing at 600 degrees C under vaccum, and residual gas, unless removed, is an impediment to HIP densification. Results also show that degassed synroc D powder in 50 kg quantities can be HIP densified to greater than 97% theoretical density at 1100 degrees C, 150 MPa, for 5h in a bellows canister without radial buckling. The authors believe that on the basis of this preliminary study, full-scale nuclear waste monoliths can be produced by HIP.
