The actual testing activities were performed and reported separately in referenced documentation. Because of this, many of the required topics below do not apply and are so noted. Test ObjectivesThis section is not applicable. No testing was performed for this investigation. Test ExceptionsThis section is not applicable. No test specification as well as test exception applies to this investigation as there was no testing was performed. Results and Performance Against Success CriteriaThis section is not applicable. No success criteria were established as there was no testing performed for this investigation. Quality RequirementsSince This report is based on data from testing as referenced. The PNNL assumes that the data from these references has been fully reviewed and documented in accordance with the analysts' QA Programs. PNNL only analyzed data from the referenced documentation. At PNNL, the performed calculations, the documentation and reporting of results and conclusions were performed in accordance with the RPP-WTP Quality Assurance Manual (RPP-WTP-QA-003, QAM). Internal verification and validation activities were addressed by conducting an independent technical review of the final data report in accordance with PNNL procedure QA-RPP-WTP-604. This review verifies that the reported results are traceable, that inferences and conclusions are soundly based, and that the reported work satisfies the Test Specification Success Criteria. This review procedure is part of PNNL's RPP-WTP Quality Assurance Manual). Test ConditionsThe scope of the RWG effort is specified in the approved WTP issue response plan (24590-WTP-PL-ENG-06-0013) and defined in subcontractor change notice (SCN) 007 and Test Specification 24590-PTF-TSP-RT-06-007, Rev 0.Demonstrate the simulant properties used for testing bracket expected actual waste properties. For non-cohesive solids (Phase 1) this includes particle size, solids density, solids concentration, liquid density, and liquid viscosity. For cohesive solids (Phase 2) this includes bulk slurry density, particle size, particle density, slurry rheology (such as consistency and yield stress) and shear strength of settled, aged sediments, as well as settled layer (heel) thickness.Waste received at the WTP will be subject to a feed specification supporting plant design and as agreed to in an Interface Control Document. This report compiles the existing Hanford Tank Farm rheological data addressed in italicized text above and establishes expected ranges for these properties for as-retrieved Hanford Tank Farm wastes. Various processes will be performed on these retrieved wastes which are expected to alter these property ranges from the as-retrieved conditions. Simulant development activities should focus on the expected properties of the waste streams under such processing conditions. v Simulant UseThis section is not applicable. No testing was performed for this investigation.
