识别核动力堆燃料组件

[中文适用范围]： 本文件规定了核电厂使用的燃料组件的唯一标识的要求。 它主要是为商业轻水反应堆燃料而开发的，但也可用于离散燃料组件中包含的任何反应堆燃料，这些燃料组件可以用本文件规定的识别码进行识别。 本文件定义了用于为燃料组件分配标识的字符和建议的顺序。 该识别旨在由燃料组件在其整个使用寿命期间进行。 本文件旨在为燃料组件识别系统提供组织原则，以保证在世界任何时间、任何地点进行明确识别（另见原子能机构安全指南第 GS-G-3.5 号）。 考虑到现有的燃料组件标识标准（例如 ANSI/ANS-57.8-1995、DIN 25433、IAEA 安全指南第 GS-G-3.5）可确保在各自应用领域中进行明确标识，本文件允许不受限制地进一步这些标准的应用。 此外，本文件旨在用作识别系统新定义的指南。 [外文原描述]： This document specifies requirements for the unique identification of fuel assemblies utilized in nuclear power plants. It was developed primarily for commercial light-water reactor fuel, but can be used for any reactor fuel contained in discrete fuel assemblies that can be identified with an identification code as specified by this document. This document defines the characters and proposed sequence to be used in assigning identification to the fuel assemblies. The identification is intended to be borne by the fuel assembly throughout its lifetime. This document aims at providing an organizing principle for fuel assembly identification systems in order to guarantee unequivocal identification at any time and any place in the world (see also IAEA Safety Guide No. GS-G-3.5). Considering that existing standards for fuel assembly identification (such as ANSI/ANS-57.8-1995, DIN 25433, IAEA Safety Guide No. GS-G-3.5) ensure unequivocal identification in their respective fields of application, this document allows without restriction the further application of these standards. Moreover, it is intended that this document be used as a guideline for new definitions of identification systems.
