This project reflects NUVIA’s EXPERTISE in the overall management of decommissioning projects involving innovative solutions.

Scope

  • Cutting, characterisation, packaging and removal of 120 supports and 94 canisters
  • Dismantling of the associated equipment
  • Radioactive clean-up of the building’s civil engineering work

Project challenges

  • Complex deck crane handling operations
  • Obsolete ventilation process
  • Canisters with different geometries
  • Waste at the bottom of the canisters
  • Layout modifications in irradiating facilities
  • Remote operations: cutting and removal

Technical solutions implemented

  • Definition of the operating methodology to minimise costs and operators’dosimetry
  • Installation of a heavy remote manipulator
  • Automatic plasma cutting of the canisters
  • Facilities modified to carry out remote filling and handling of packages, immobilization of the content using hydraulic binder
