Abstract

One aspect of the invention provides a system for treating wastestream, particularly a liquid or aqueous radwaste, for safe disposal and, in final processing, converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. Another aspect provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I) to inactivate or destroy existing chelants, Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing. Still further aspects of the invention address the recovery and safe handling of substances such as C-14.
