Tank 29 salt removal method using slurry pump agitation
This report outlines a plan for removing salt from Tank 29. The plan is based, in part, upon the experience gained in the removal of salt from Tank 19 and sludge from Tank 16. Tank 19 was the first tank in which slurry pumps were used during salt dissolution. Salt in Tank 29 will be dissolved to form a nearly saturated salt solution. The goal of Waste Removal is to remove the salt from the tank and deliver it to In-Tank Precipitation (ITP) at a concentration greater than 6.7 molar Na{sup +} (including dilution from transfer steam) to meet ITP requirements. (The amount of wash water used in ITP will be enough to dilute 6.7 molar Na{sup +} salt solution to 5 molar Na{sup +} required for the precipitation step). The solution will be sent to (ITP) for precipitation of soluble cesium and strontium (radioactive elements). The precipitate will be transferred to the Defense Waste Processing Facility (DWPF) for final disposal. A USQD (Unreviewed Safety Question Determination) for criticality safety issue resolution will be completed prior to salt removal.
