SGS holds free webinars on advanced ultrasonic testing in nuclear power plants and TOFD


With the tragic consequences of the recent tsunami that hit Japan still in the headlines, and the consequent devastating impact on the nuclear power plant at Fukushima still causing widespread concern and panic, the focus on thorough nuclear power plant testing has never been greater. It is from this perspective that the SGS Competence Centre for Non-Destructive Testing decided to host a free
60 minute webinar on providing ‘An Introduction to Ultrasonic Testing for the Pre-service and In-service Inspection of Nuclear Power Plants’. In addition, SGS provided another free 60 minute webinar on
‘Time-of-Flight Diffraction (TOFD): Theory and Practice’ due to the growing interest in this non-destructive testing technique.

In the webinar on ‘An Introduction to Ultrasonic Testing for the Pre-service and In-service Inspection of Nuclear Power Plants’, SGS informed participants about the application of advanced techniques for the pre-service inspection and in-service inspection of nuclear power plants. SGS also provided information regarding how a pre-service inspection can benefit the in-service inspection, and how thorough design aids the application of in-service inspections. With an inspection approach that combines various essential elements, SGS seeks to implement strategies that detect possible degradation mechanisms in their very earliest stages. SGS also seeks to monitor all damage and ensure reproducibility during multiple interventions.

The other free webinar SGS offered was about time-of-flight diffraction and through this webinar SGS informed participants about the characteristics of this testing method as well as its advantages and disadvantages. Furthermore, SGS provided attendees with thorough information on pre-service and in-service applications of TOFD. With its extensive experience and expertise in the field of non-destructive testing, SGS provides not only the theoretical background but also very useful practical information, backed by various examples of TOFD scans.

Hosted by Ton Kooren, Global Expert Advanced NDT, and Norbert Trimborn, Strategic Business Leader Advanced NDT, respectively, the free 60 minute webinars were available during April across the globe in Asia, Europe, the Americas and Africa. Each of the webinars was available in four sessions to meet the needs of attendees in every time zone.

In addition to being one of the largest TOFD providers in the world, SGS claims that it was the first company to use certified EN473 TOFD LII operators for TOFD inspections. With around 80 highly experienced TOFD LII operators worldwide, SGS provides comprehensive time-of-flight diffraction tests in all four corners of the world. Furthermore, having the same quality level of TOFD inspection in all countries, SGS has a wide range of superior training facilities for TOFD in locations around the world.

The SGS NDT Training and Examination Centre is a BINDT accredited training organisation (ATO) and an authorised qualifying body (AQB) for TOFD. SGS trains and certifies people to the highest inspection standards and is qualified to conduct both the required pre-examination training and the PCN examinations for Levels 1, 2 and 3.

The scope of NDT services offered by SGS covers both conventional and advanced NDT methods, which are provided by qualified inspectors in accordance with international standards.
