Forsberg, C. W.

Exploratory experiments were conducted to find methods of removing /sup 14/C-contaminated CO/sub 2/ with a Ca(OH)/sub 2/ slurry from off-gas streams without removal of /sup 85/Kr. Purging the product CaCO/sub 3/ slurry, created by reacting CO/sub 2/ and Ca(OH)/sub 2/, with a small amount of gas appears effective in the removal of any residual krypton from the CaCO/sub 3/. It therefore appears feasible to remove /sup 14/C-contaminated CO/sub 2/ before removal of /sup 85/Kr from HTGR off-gas streams and hence reduce the volume flow rate to the /sup 85/Kr removal equipment with significant cost savings.
