We are pleased to share the success of our latest project aimed at changing the way radioactive waste stored in drums is handled and characterized. 

Our Czech NUVIATech Automation team has successfully designed, manufactured, and implemented the first part of a fully automated system that showcases the combination of our unique know-how in automation, radiation measurement, software development, and detector technology.

Start date: June 2022

End date: April 2024

This project is intended to automate the characterization of radioactive waste at Nuclear Plants, and make the characterization process more effective, safer for operators and more reliable due to process repeability. The aim of the project was design, software development, manufacturing, installation on site and commissioning of two different systems.

Key details

  • General Contracthor: NUVIA CZ

  • Country: Belgium

Scope

  • Two fully automatic systems to characterize solid waste stored in 200 l and 400 l drums.
  • Pseudo-contact gamma dose rate measurement on 100% of the surface performed by custom-designed detector fitted to industrial 6-axis robot.
  • Surface alpha + beta contamination monitoring performed on predefined areas – automatic manipulation with wipe by custom-designed exchangeable robot tool.
  • HPGe detector and software package for precise nuclide activity determination.
  • All levels of software (from system control to data analysis, archiving and reporting) integrated in a single software solution.
  • Fully automatic daily QA control performed by robot with test sources (alpha, beta, gamma).

Challenges

Integration of various approaches to fully automate the process. Interdisciplinary cooperation combining of automation, radiometric systems, software development, detectors technology. Tailor-made solution based on customer requirements.

Solution

Unconditioned waste

  • Transported in 220l yellow drums
  • Contact dose rate < 2mSv/h
  • Weight up to 400kg
  • Non-treated

The system consists of:

  • Automated U-shaped roller conveyor
  • 6-axis industrial robot (including 4 interchangeable tools)
  • Electrically cooled HPGe detector
  • Dose rate detectors
  • Fully automated surface contamination measurement
  • Integrated weighing system
  • Software

 

Conditioned waste

  • Transported in 400l black drums by AGV’s Automatic Guided Vehicles
  • Contact dose rate up to 1Sv/h
  • Weight up to 1500kg

System consists of:

  • Automatic frame for lifting and handling the barrel to the defined position for measurement
  • 6-axis industrial robot (including 4 interchangeable tools)
  • Electrically cooled HPGe detector
  • Dose rate detectors
  • Fully automated surface contamination measurement
  • Software
  • The design includes an independent emergency control system release and release of the drum from the structure
