What is ISO 20890‑2 about?
ISO 20890‑2 is the second part of the multi-series European standard that specifies guidelines for pre-service inspections (PSI) and in-service inspections (ISI) of the surfaces using magnetic particle testing and penetrant testing on components of the reactor coolant circuit of light water reactors. Test systems for the localisation of surface inhomogeneities and requirements for test personnel, test devices, test media, accessories as well as optical auxiliaries, the preparation and implementation of the test, as well as the recording, are defined.
ISO 20890‑2 guidelines are also applicable to other components of nuclear installations.
NOTE: 1) Data concerning the test section, test extent, inspection period, inspection interval and evaluation of indications are defined in the applicable national nuclear safety standards.
2) In general, ISO 20890‑2 is by ISO 3452 and ISO 9934 series. ISO 12749-2 provides details to be considered in the standard test procedure (see Annex A).
Who is ISO 20890‑2 for?
ISO 20890‑2 on light water reactors applies to:
- Nuclear power plants
- Mechanical Engineers
- Chemical engineer
- Nuclear research organisations
- Nuclear research scientists and researchers
- Nuclear regulatory authorities
Why should you use ISO 20890‑2?
ISO 20890‑2 provides guidelines with pre-service inspections (PSI) and in-service inspections (ISI) pre-service inspections (PSI) of reactor coolant circuits of light water reactors which extends the service life and efficiency of the light water reactor.
ISO 20890‑2 assists you in performing inspection by magnetic particle testing and penetrant testing on light water reactor components by providing guidelines on test systems for the localization of surface inhomogeneities and requirements for test personnel, test devices, test media, accessories, as well as optical auxiliaries, test preparation and execution, and test recording. For the purpose to ensure the reliability and comparability of tests performed on components of the reactor coolant circuit of light water reactors.
Overall, ISO 20890-2 establishes guidelines for preservice and in-service inspection of reactor coolant circuits using automated ultrasonic testing devices which will benefit the users as they can inspect the components earlier than they will break down and therefore save from any accident conditions.
