What is ISO 20890-3 about?
ISO 12749-3 is the third part of the multi-series European standard that specifies guidelines for in-service system pressure tests of the reactor coolant circuit of light water reactors.
ISO 20890-3 specifies the test technique, the requirements for measuring equipment and additional devices, the preparation and performance of the test as well as the recording and documentation, for the purpose to ensure the reliability and comparability of tests.
Note: Data on (test) pressure, (test) temperature, the scope of testing, rates of change of pressure and temperature, test schedule and inspection intervals can be obtained from the applicable national nuclear codes.
Who is ISO 20890-3 for?
ISO 20890-3 on light water reactors is relevant to:
- Nuclear power plants
- Mechanical Engineers
- Chemical engineer
- Nuclear research organizations
- Nuclear research scientists and researchers
- Nuclear regulatory authorities
Why should you use ISO 20890-3?
ISO 20890-3 provide guidelines for in-service system pressure tests of the reactor coolant circuit of light water reactors, which extends the service life and efficiency of the light water reactor.
ISO 20890-3 assists you with a test method and provides the requirements for measuring equipment and additional devices, the preparation and performance of the test as well as the recording and documentation, for the purpose to ensure the reliability and comparability of tests performed on reactor coolant circuit of light water reactors.
ISO 20890-3 describes the performance of in-service system pressure tests of light water reactor coolant circuits. In-service system pressure tests are a critical procedure that should be performed by defined instructions and guidelines.
Overall, ISO 20890-3 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.
