轻水堆一次冷却剂回路部件在役检验指南第4部分:目视检验

[中文适用范围]： 本文件给出了轻水反应堆反应堆冷却剂回路部件及其装置的服役前检查（PSI）和在役检查（ISI）指南，以直接或远程目视测试的形式进行——一般目视测试（概述） ，或 — 选择性视觉测试（特定属性）。 本文件也适用于核设施的其他部件。 本文件中的要求侧重于远程（机械化）视觉测试，但也指定了直接视觉测试的全局要求。 有关焊缝直接目视测试的具体要求，请参阅 ISO 17637。 本文件不适用于与压力和泄漏测试以及定期工厂检查结合进行的一般状态测试。 本文件规定了允许识别与预期状态偏差的测试方法、对设备技术和测试人员的要求、测试的准备和实施以及记录。 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适用的国家核安全标准中规定。 [外文原描述]： This document gives guidelines for pre-service inspection (PSI) and in-service inspections (ISI) for reactor coolant circuit components of light water reactors and their installations as direct or remote visual testing in the form of a — general visual testing (overview), or — selective visual testing (specific properties). This document is also applicable to other components of nuclear installations. The requirements in this document focuses on remote (mechanized) visual testing, but also specifies global requirements for direct visual testing. For specific requirements for direct visual testing of welds see ISO 17637. This document is not applicable to tests in respect to the general state that are carried out in conjunction with pressure and leak tests and regular plant inspections. This document specifies test methods that allow deviations from the expected state to be recognised, requirements for the equipment technology and test personnel, the preparation and performance of the testing as well as the recording. NOTE Data concerning the test section, test extent, inspection period, inspection interval and evaluation of indications is defined in the applicable national nuclear safety standards.
