Designation:C175011Standard Guide forDevelopment,Verification,Validation,and Documentation ofSimulated High-Level Tank Waste1This standard is issued under the fixed designation C1750;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 Intent:1.1.1 The intent of this guideline is to provide generalconsiderations for the development,verification,validation,and documentation of high-level waste(HLW)tank simulants.Due to the expense and hazards associated with obtaining andworking with actual wastes,especially radioactive wastes,simulants are used in a wide variety of applications includingprocess and equipment development and testing,equipmentacceptance testing,and plant commissioning.This standardguide facilitates a consistent methodology for development,preparation,verification,validation,and documentation ofwaste simulants.1.2 This guideline provides direction on(1)defining simu-lant use,(2)defining simulant-design requirements,(3)devel-oping a simulant preparation procedure,(4)verifying andvalidating that the simulant meets design requirements,and(5)documenting simulant-development activities and simulantpreparation procedures.1.3 Applicability:1.3.1 This guide is intended for persons and organizationstasked with developing HLW simulants to mimic certaincharacteristics and properties of actual wastes.The process forsimulant development,verification,validation,and documen-tation is shown schematically in Fig.1.Specific approvalrequirements for the simulants developed under this guidelineare not provided.This topic is left to the performing organi-zation.1.3.2 While this guide is directed at HLW simulants,muchof the guidance may also be applicable to other aqueous basedsolutions and slurries.1.3.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 User Caveats:1.4.1 This guideline is not a substitute for sound chemistryand chemical engineering skills,proven practices and experi-ence.It is not intended to be prescriptive but rather to provideconsiderations for the development and use of waste simulants.1.4.2 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C1109 Practice for Analysis of Aqueous Leachates fromNuclear Waste Materials Using Inductively CoupledPlasma-Atomic Emission SpectroscopyC1111 Test Method for Determining Elements in WasteStreams by Inductively Coupled Plasma-Atomic EmissionSpectroscopyC1752 Guide for Measuring Physical and Rheological Prop-erties of Radioactive Solutions,Slurries,and SludgesD4129 Test Method for Total and Organic Carbon in Waterby High Temperature Oxidation and by CoulometricDetection2.2 Environmental Protection Agency SW-846 Methods:Method 3010A Acid digestion of Aqueous Samples andExtracts for total metals for Analysis by FLAA or ICPSpectroscopyMethod 3050B Acid Digestion of Sediments,Sludges andSoilsMethod 3051A Microwave Assisted Acid Digestion ofSediments,Sludges and SoilsMethod 3052 Microwave Assisted Acid Digestion of Sili-ceous and Organically Based MatriciesMethod 6010C Inductively Coupled Plasma-Atomic Emis-sion SpectrometryMethod 6020A Inductively Coupled Plasma-Mass Spec-trometry1This specification is under the jurisdiction of ASTM Committee C26 onNuclear Fuel Cycle and is the direct responsibility of Subcommittee C26.13 onSpent Fuel and High Level Waste.Current edition approved June 1,2011.Published September 2011.DOI:10.1520/C1750-11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Method 9056A Determination of Inorganic Anions by IonChromatography3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 cognizant engineer,nlead engineer responsible foroverall supervision and direction of simulant development.3.1.2 simulant,na solution or slurry that mimics orreplicates selected chemical,physical or rheological properties,or both,of an actual process or waste stream.3.1.3 simulant development test plan,na document thatdescribes the simulant development process that results in asimulant that meets the usage and design requirements identi-fied in the simulant requirements specification.3.1.4 simulant preparation procedure,na document thatspecifies the step by step process of
