Radioiodine control in incinerator offgas
Incineration of waste contaminated with radioiodine has been studied in the Mound laboratory-scale cycle incinerator. Iodine species were found to volatilize from the burn chamber almost completely, but were captured in the offgas system by the combination of a wet scrubber, silver zeolite bed, and dry filters. Various scrub liquor compositions were tested to obtain the best iodine absorption efficiency. A caustic scrubber showed reasonable efficiency which could be increased by the addition of 1.5 wt% KI. The effect of the chemical form of iodine in the feed was also studied briefly. The behavior of the iodine contamination, whether the chemical species was I/sub 2/ or NaI, was much the same. A study of silver zeolite employed in the incinerator offgas system showed that the silver zeolite must be protected against contamination by carbonaceous material for longterm efficiency.
