1.1 意图: 1.1.1 本指南旨在为危险材料（例如放射性废物）和工艺流的储罐模拟物的开发、验证、验证和记录提供一般考虑因素。由于获取和使用实际危险材料（尤其是放射性废物）的相关费用和危害，模拟物被广泛用于各种应用，包括工艺和设备开发和测试、设备验收测试和工厂调试。本标准指南为模拟物的开发、准备、验证、验证和记录提供了一致的方法。 1.2 本指南提供了以下方面的指导:( 1. )定义模拟使用( 2. )定义模拟设计要求( 3. )开发模拟准备程序( 4. )验证模拟物是否满足设计要求，以及( 5. )记录模拟开发活动和模拟准备程序。 1.3 适用性: 1.3.1 本指南适用于负责开发模拟物的人员和组织，以模拟危险材料的某些特征和特性，或为正在评估的现象提供代表性性能。模拟开发、验证、确认和文档编制过程如所示 图1 . 未提供根据本指南开发的模拟物的具体批准要求。此主题留给执行组织。批准要求与模拟物的设计、补给程序和生产的最终模拟物有关。 图1 模拟开发、验证、确认和文件流程图 1.3.2 虽然本指南针对放射性材料（例如核废物）的模拟物，但本指南也适用于其他水基溶液和泥浆。 1.3.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本指南不能替代良好的化学和化学工程技能、经验证的实践和经验。其目的不是规范性的，而是为模拟物的开发和使用提供考虑因素。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 Intent: 1.1.1 The intent of this guide is to provide general considerations for the development, verification, validation, and documentation of tank simulants for hazardous materials (for example, radioactive wastes) and process streams. Due to the expense and hazards associated with obtaining and working with actual hazardous materials, especially radioactive wastes, simulants are used in a wide variety of applications including process and equipment development and testing, equipment acceptance testing, and plant commissioning. This standard guide facilitates a consistent methodology for development, preparation, verification, validation, and documentation of simulants. 1.2 This guide provides direction on ( 1 ) defining simulant use, ( 2 ) defining simulant-design requirements, ( 3 ) developing a simulant preparation procedure, ( 4 ) verifying and validating that the simulant meets design requirements, and ( 5 ) documenting simulant-development activities and simulant preparation procedures. 1.3 Applicability: 1.3.1 This guide is intended for persons and organizations tasked with developing simulants to either mimic certain characteristics and properties of hazardous materials or provide representative performance for the phenomenon being evaluated. The process for simulant development, verification, validation, and documentation is shown schematically in Fig. 1 . Specific approval requirements for the simulant developed under this guide are not provided. This topic is left to the performing organization. Approval requirements are associated with the design of the simulant, makeup procedures, and final simulant produced. FIG. 1 Simulant Development, Verification, Validation, and Documentation Flowsheet 1.3.2 While this guide is directed at simulants for radioactive materials (for example, nuclear waste), the guidance is also applicable to other aqueous based solutions and slurries. 1.3.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This guide is not a substitute for sound chemistry and chemical engineering skills, proven practices and experience. It is not intended to be prescriptive but rather to provide considerations for the development and use of simulants. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
