DESCRIPTION

19/30402594 DC


This standard 19/30402594 DC BS ISO 20890-6.2. Guidelines for in-service inspections for primary coolant circuit components of light water reactors is classified in these ICS categories:
  • 27.120.10 Reactor engineering

This document specifies fundamental techniques for pre-service inspection (PSI) and in-service inspections (ISI) by radiographic testing conducted on components in the reactor coolant circuit of light water reactors. This document is also applicable to other components of nuclear installations. This document specifies the RT-inspection for wall thicknesses below or equal 25 mm. The RT-inspection of components with higher wall thicknesses is specified in ISO 17636-series (all parts).

Test systems for the validation of inhomogeneities (surface and volume) 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.

An in-service radiographic test in respect to corrosion and wall thickness abrasion of base material areas is the object of EN 16407-1 and EN 16407-2.

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.
