ABSTRACT:
A method for solidifying medium radioactive aqueous waste liquids, low radioactive aqueous waste liquids, and aqueous waste liquids containing tritium for final non-contaminating storage. The waste liquids are first mixed with absorbing agents, e.g., clay-like substances, hydraulic binders or mixtures thereof, to form granules or pellets of the same. The granules or pellets are then embedded with a binder which is initially present in a liquid state and later hardens. However, granules or pellets formed from medium radioactivity aqueous waste liquids or waste liquids containing tritium compounds are first clad in a first binder and thereafter embedded for final solidification with a second binder.
