Danieli Henschel is installing scrap shear at the CERN

The European Organisation for Nuclear Research is one of the world’s largest and most prestigious scientific laboratories.

It focuses on fundamental physics, probing the components and the laws of the Universe, using extremely complex scientific instruments to study the basic constituents of matter: the fundamental particles. By studying what happens when these particles collide, physicists learn more about the laws of nature. Around 14 000 employees work on the CERN site close to Geneva.

The World Wide Web was invented at the CERN in 1989 by British physicist Tim Berners-Lee. The Large Hadron Collider (LHC) is also at the CERN. With its 27 kilometre circumference, the LHC is the world’s largest particle accelerator. In 2012, scientists were able to observe the Higgs boson using it and, just a few weeks ago, the pentaquark was identified.

Why do they need scrap shears at the CERN?

All the research and experiments carried out at the CERN generate considerable tonnage of metallic materials that may be slightly contaminated with a level of radioactivity that requires putting it in specific containers to be buried. In order to minimise the cost of burying the material, the CERN wanted to cut it to optimise its compaction prior to burying.

The CERN teams have always stored the metallic waste in one of their first particle accelerator storage rings that is no longer in use and the Danieli Henschel shears have been installed in one of the ring’s rooms.

A success for Danieli-Henschel

In 2012, the CERN launched a European tender to acquire scrap shears adapted to its needs. Danieli Henschel was selected as supplier in December 2012 because of the quality of its offer and its experience in processing contaminated materials.

The machine manufactured for the CERN was based specifically on the client’s specifications on the basis of a CIV type 600-8 electric scrap shear which respects particularly strict safety requirements.

It offers the following functionalities:

  • Complete protection cover above bed and shear discharge with de-dusting to remove all possible radioactive dust (6.000 m3 / h)
  • Cabin connected to separate air supply and equipped with air outlet
  • Monitor for video cameras
  • Remote control of all equipment: feeding, shearing, transport, packing
  • Mobile filtration system for emptying and filling
  • Barely inflammable hydraulic oil
  • Automatic barrel-filling device
  • Steel nets holding hydraulic hoses in position in case of breakage and preventing from dangerous oscillation
  • Visual & audible alarm for machine motion
  • Locking brakes holding shearing ram and clamp, with electrical sensor, to be manually inserted during maintenance operations in this area
  • Remote diagnosis per modem for supplier assistance.
  • Lateral pusher on the shear head (“cupola”) to increase compaction of the processed material.

On July 21st 2015, following a fruitful collaboration between the teams from the CERN and Danieli Henschel, and in compliance with the agreed schedule, the new shear and all its peripheral equipment was put into service.
