标准摘要
[中文适用范围]： 本文件提供了对轻水堆非铁磁蒸汽发生器加热管进行涡流试验的服役前检查（PSI）和在役检查（ISI）的指南，其中试验是使用机械化测试设备从外部进行的。 管内侧。 作为主回路组件的蒸汽发生器加热管塞的在役涡流测试不是本文件的主题。 由于蒸汽发生器加热管塞的实施方式不同，需要使用专门适配的测试系统来进行鉴定。 定义了用于定位不均匀性（表面）的测试系统以及对测试人员、测试设备、测试和设备系统的准备、测试的实施以及记录的要求。 注：有关试验段、试验范围、检查周期、检查间隔和指标评价的数据在核安全标准中规定。 建议技术规格基于均匀弯曲半径的 U 型管弯管的经验（类似于 S/KWU 设计）。 为了测试其他类型的弯管（例如带有两个 90° 弯头的 U 型弯管），将提供进一步的资格认证。 [外文原描述]： This document gives guidelines for pre-service inspection (PSI) and in-service inspections (ISI) by eddy current tests on non-ferromagnetic steam generator heating tubes of light water reactors, whereby the test is carried out using mechanised test equipment outwards from the tube inner side. An in-service eddy current test of steam generator heating tube plugs as a component of the primary circuit is not an object of this document. Owing to the different embodiments of steam generator heating tube plugs, the use of specially adapted test systems to be qualified is necessary. Test systems for the localisation of inhomogeneities (surface) and requirements for test personnel, test devices, the preparation of test and device systems, the implementation of the testing as well as the recording are defined. NOTE Data concerning the test section, test extent, inspection period, inspection interval and evaluation of indications is defined in the nuclear safety standards. It is recommended that the technical specifications are based on experience on U-tube bends with even bend radius (similar to the S/KWU design). To test other kind of tube bends (e.g. U-tube bends with two 90° bends) further qualifications will be provided.
