specially designed :o optimize solidificacion of all types of radioactive wastes - evapora:or boctoms, ion-exchange resin slurries, sludges, and decontamination solvents. The Dow solidification process can successfully treat liquids ranging in pH from 2.5 to 11.0 and wastes containing high concentra-tiens of dissolved and undissolved solids.

Though it will usually not be necessary to pretreat the waste or to add an addi:ional chemical (en: ender),

the sample verification procedure will indica:e if pretreatment or extender 2ddition will be required for optimus solidification.

The volu=es of process agents added will also .be determined according to sa=ple verification procedure.

a. Preparations for mobile unit use.

(1) Installation of flanges to join mobile unit to external station connections.

(2) Receipt of binder.

b. Sampling requirements prior to solidification.

(1) Recirculation of resin and concentrates to obtain representative sample.

(2) Sample collection using installed samplers.

(3) Analysis of sample for radionuclides present and radioactive content, and perform calculations for solidification.

c. Transfer of waste to vendor unit.

(1) Operation of cranes to move liners into place for solidification.

(2) Operation of pumps and radwaste panels in the station to move waste and binder.*

d. Verification of acceptable product.

(1) Review of process control analysis.

(2) Inspection of final product.

e. Preparations for shipment.

(1) Installation of cask lids.

(2) Inspection of trucks.

(3) Performance of surveys to determine radiatien and contamination levels.

(4) Performance of calculations for shipment based on analytical data; determine shipping requirements.

(5) Coordination of shipments with shipper, appropriate state agencies, and burial facility.

7.2 Vendor Responsibilities The vendor shall be responsible for:

a. Determining the chemical ratios needed to achieve l

solidification based on station analytical data. If station samples are not available, obtain sample using vendor equipment.

b. Running the process control analysis.

c. Submitting the prccess control analysis to station Radwaste Chemistry Supervisor prior to commencement of solidification operations

d. Operating the solidification process equipment.*

e. Specifying and ordering replacement chemicals.

• NOTE: Either station or vendor personnel can terminate the transfer of waste and binder using remete-operation of appropriate station pumps.
