HOW CAN WE HELP YOU?

EDAS® inspects pressure vessels and piping in nuclear plants. Engineers have integrated EDAS into underwater inspection robots to replace older, bulkier equipment. The state-of-the-art EDAS-IV inspection system allows for rapid and effective examination of nuclear power plant reactor vessels. It is used to inspect reactor pressure vessels around the world.

The robot with EDAS reduces the difficulty of performing boiling water reactor (BWR) weld inspections inside the reactor. The technology is also being investigated for inspection of other BWR vessel internal components such as core shroud assembly welds.

Enhanced Data Acquisition System (EDAS®-IV)

EDAS-IV is a state-of-the-art ultrasonic inspection system for use in NDE of large structures. Designed to allow rapid and effective examinations of nuclear power plant reactor vessels, EDAS-IV includes:

  • Programmable ultrasonic instruments
  • Data acquisition and analysis workstations
  • Remote pulser preamp system
  • Parallel calibration stations

The EDAS-IV inspection system represents the newest generation of SwRI's enhanced data acquisition equipment used to inspect 15% of the world's reactor pressure vessels (RPV). This inspection system records full waveform data from up to 16 data channels simultaneously at scan speeds of as high as 6 inches (150 mm) per second.
