Summar

25、y of Guide4.1 This guide provides general considerations on the development, preparation, validation, verification, and documentation ofHLW simulants.FIG. 1 Simulant Development, Verification, Validation, and Documentation FlowsheetC1750 1724.2 The first step in the process is to define the purpose

26、for which the simulant will be used. used and to identify the key processperformance metrics or properties, or both, relevant to the phenomenon being assessed. The performance metrics/parametersprovide a means of comparing simulant performance against that for actual waste (based on available perfor

27、mance orcharacterization data, or both, for the waste) for the process or phenomenon being evaluated.This first step also includes specifyingthe target values or range of values for the chemical composition and physical and rheological propertiesproperties (includingrheology) of the simulant. The qu

28、ality assurance requirements are also defined in the first step in accordance with the projectrequirements for which the simulant is being developed.4.3 The next step is to define the simulant design requirements. This involves determining the necessary and sufficient simulantproperties to be measur

29、ed for each affected unit operation. Key simulant properties and acceptance criteria are developed withregard to the project requirements for which the simulant is being developed. Standardized chemical, physical chemical andrheologicalphysical property measurements are referenced. Topics to be cons

30、idered during the development and scale-up of thesimulant preparation procedure are provided.Amethodology for validation and verification of the simulant is discussed along withsuggested documentation.4.4 The following step is to define an approach for developing the simulant to meet the needs for s

31、imulant use while satisfyingthe design requirements. This approach is often documented in a test plan that includes the methods for validating the use of thefinal developed simulant and verifying the simulant is acceptable.4.5 Upon developing an approach and simulant, a procedure for preparing the s

32、imulant must be generated and documented. Theprocedure is focused on providing a means for consistently generating the correct simulant regardless of persons conductingprocess. The procedure takes into account sequence constituents are added, degree of mixing, and temperature at which processestake

33、place. The development of the preparation procedures must address scale-up associated with fabricating larger batches ofsimulant, and simulant contamination, degradation, or attrition during testing.4.6 Once the fabrication of simulant is initiated, the simulant being produced needs to be verified.

34、Verification assures thesimulant meets design requirements and address the question: was the simulant made properly?4.7 At the end of the simulant process, documentation for the simulant development process needs to be compiled and finalized.The documentation must meet project requirements for produ

35、cing records materials and focus on assuring the repeatability of theprocess.5. Significance and Use5.1 The development and use of simulants is generally dictated by the difficulty of working with actual radioactive or hazardouswastes, or both, and process streams. These difficulties include large c

36、osts associated with obtaining samples of significant size aswell as significant environmental, safety and health issues.5.2 Simulant-Development Scope Statement:5.2.1 Simulant Use Definition:5.2.1.1 The first step should be to determine what the simulant is to be used for. Simulants may be used in

37、a wide variety ofapplications including evaluation of process performance, providing design input to equipment, facilities and operations,acceptance testing of procured equipment or systems, commissioning of equipment or facilities, or troubleshooting operations inexisting equipment or facilities.As

38、imulant may be used for single or multiple unit operations. Through the simulant-use definition,the characteristics of the simulant required for development are determined. The characteristics may include chemical, physical,rheological or a combination of these properties. The simulant-use definitio

39、n should identify the key process performance metricsor properties, or both. For example, if pipeline transport of non-buoyant solids in an aqueous liquid is the phenomena beingevaluated, solids properties significant to the process performance can be different than those characteristics for the sam

40、e simulantforming settled sediment that has a yield stress in a vessel, and the associated performance metrics are different. Similarly,significant difference in simulant solid particle performance properties may be required to evaluate waste impact on equipmentassociated with abrasive wear and fret

41、ting. The use of key process performance metrics allows changes in simulant compositionto be evaluated and compared with other compositions and the actual waste. The effect of process chemical additions and recyclestreams must also be assessed.5.2.1.2 The applicable quality assurance requirements sh

42、ould be specified in accordance with the projects quality assuranceprogram. For example in the DOE complex, these requirements often include a QA program that implements ASME NuclearQuality Assurance, NQA-1 (latest revision or as specified by project) and its applicable portions of Part II, Subpart

43、2.7 (latestrevision or as specified by project) or Office of Civilian Radioactive Waste Management Quality Assurance RequirementsDocument: QARD DOE/RW 0333P (latest revision or as specified by project) QA requirements. Simulant-development activitiesthat support regulatory and environmental complian

44、ce-related aspects of a waste-vitrification program may need to be performedin accordance with project quality-assurance requirements for generating environmental regulatory data. The use of simulants forproject testing that is exploratory or scoping in nature may not need to comply with specific QA

45、 requirements.5.2.2 Simulant Composition Definition:C1750 1735.2.2.1 Approaches to simulant-composition development will vary depending on the type of simulant required for testing.Simulant compositions may be based on actual sample characterization data, formulated for specific unit operations, or

46、used forbounding or testing the limits of a process or specific piece of equipment. Key properties that are to be simulated should beidentified as it may be difficult and unnecessary to develop simulants that exactly mimic all actual process stream properties atonce. These key properties may be iden

47、tifiefd based on the key process performance metrics (refer to 5.2.1.1) used to evaluatesimulant performance relative to the phenomenon being investigated.5.2.2.2 Compositions for simulants based on actual waste samples should be defined using the available characterization dataas the starting point

48、 (see Fig. 2). The best available source-term analytical data, including uncertainties, along with a comparisonagainst comparable inventory data, historical process information, or feed vectors must be assessed. This comparison shouldhighlight analytical outlier values that will need to be addressed

49、 for an analyte.5.2.2.3 For simulant compositions that mimic flow sheet streams later in the process (after the best available waste source-termanalytical information on the incoming waste stream is defined), process flow sheet model runs may be required to provideestimates of the additional stream compositions that incorporate recycle streams from other flow sheet unit operations. Flow sheetruns should consider transient behavior of the process in order to provide a range of compositions such that bounding conditionscan be determined. The compositional waste-st
