Results are presented for the fourth major campaign for quantifying krypton removal from simulated High-Temperature Gas-Cooled Reactor reprocessing off-gas by the Krypton Absorption in Liquid CO/sub 2/ (KALC) process. This process utilizes the high solubility of krypton in liquid CO/sub 2/. Mass transfer experiments for the absorption, fractionation, and stripping operations of the KALC process indicate that the addition of N/sub 2/ and CO do not alter the mass transfer characteristics exhibited by O/sub 2/ and krypton in the basic CO/sub 2/--O/sub 2/--Kr system. Decontamination factors for xenon in the absorber and stripper were several orders of magnitude less than those for krypton under similar conditions. Indications are that the fate of xenon is controlled by the heat input to the stripper reboiler. Experiments on the solubility of O/sub 2/ and CO indicate that CO is more soluble than O/sub 2/ at temperatures below -21/sup 0/C.
