Mechanised inspections

DEKRA Industrial AB is accredited by the Swedish Board for Accreditation and Conformity Assessment (SWEDAC) to carry out independent, third-party non-destructive testing (NDT) in accordance with the requirements of the relevant authorities in Sweden. This accreditation also includes the supplementary requirements imposed by the Swedish Work Environment Authority and the Swedish Radiation Safety Authority.

DEKRA Industrial offers a full spectrum of advanced mechanised inspection services and is a specialist in the nuclear power industry.

Manufacturing inspection/Periodic inspection

We perform mechanised NDT employing all of the more commonly used methods:

  • Penetrant testing (PT)
  • Ultrasonic testing (UT)
  • Eddy current testing (ET)
  • Visual testing (VT)
  • Moulding VT (A-VT)

Examples of components

Most components in a nuclear plant need specific development of manipulators and testing methods. The examples below include both specific manipulators and specially developed testing methods, and in many cases our own probes and transducers to be able to meet the requirements from clients and authorities. We have experience from working in all commercial types of reactors, such as; BWR, PWR, VVER and RBMK.

For example

  • Vessel welds
  • Vessel head welds
  • Vessel head penetrations
  • Nozzles
  • Bottom-mounted nozzles
  • Piping

The process

When developing new applications for different testing methods and manipulators, we normally start by interpreting requirements from authorities and qualification body, often together with our client. This gives us the possibility to plan the technical development and design work. During technical development we use our own probe shop, tightly integrated with the rest of our lab, in order to find the optimum method for the specific application.
