2 phases are forseen for the 287-Power Lab.

  • Phase 1: Power Lab only.
    • Standard Lab for repairing heavy Power Modules.
    • Layout integrates a vestibule (sas), but door is let opened per default.
    • Layout integrates boxes for clothes, with the possibility to wear them (change clothes process with 2 personnal cases).
    • One "dust-remove" station.
    • All material inside is marked and traced, and must not leave the lab.

  • Phase 2: R2E/Rad Power Lab.
    • Tranformation of the power lab into a Radiation Lab.
    • vestibule (sas) integrates a PAD (personal ...), and door is locked per default; a card reader grants access only.
    • Ventilation upgraded, filter adapated to radiation environnement.
    • Entering the lab requires specific clothes.
    • All material inside is marked and traced, all intervention are reported in an informatic system.

Projective Planning


  • Ventilation system has to put lab under pressure to avoid any risk of contaminated air to exit the lab.
  • Ventilation system use specific high filtration filters for radiation purposes.
  • All surfaces must be non porous, and should be easily washable.
  • Evacuation scheme should be clear.
  • A vestibule (sas) is mandatory. It integrates
    • A safety lock access (card reader) to enter the lab.
    • Dedicated boxes to change clothes (private => radiation protection).
    • A radiaton pad (hand + feets) to ckeck contamination when exiting the lab.
