ModuCon® - Modular Containment System

A good example of our track record and the flexibility and safety of the system in adapting to various situations relates to the decommissioning of over 60 glove boxes used for mixed oxide fuel fabrication for over 20 years.

Glovebox dismantling operations within a ModuCon MCSThis work was carried out ‘in situ’ at Winfrith Technology Centre; the proving ground for the system and associated procedures. The work involved progressively dismantling, decontaminating and packing a variety of small glove boxes and larger fixed installations including ball mills, a heavy press and several furnaces. The furnace, standing over 2m high, was enclosed in an MCS fitted with a waste port and shower tunnel and sealed with a strippable coating in preparation for decommissioning. The furnace was dismantled and size reduced by operators in full airfed suits and the waste drummed for disposal. On completion the containment was cleared and sprayed with a final tie-down coating in readiness to accept a number of smaller glove boxes for size reduction and disposal.

The two year programme was completed to time and cost. The containments were dismantled and cleaned ready for the final phase of work.

A containment was constructed adjacent to the laboratory pressurised suit area to fulfil two important functions:

  1. Create a safe, sound working environment for decommissioning operations including:
    • decontamination using water jetting
    • size reduction using hand tools
    • packing wastes for disposal
  2. Replace the building services during operations prior to demolition, this included the removal of:
    • active drains
    • HEPA ventilation system
    • water, air and electricity

The work was completed safely with ModuCon® playing a key role in decontamination and decommissioning operations: providing a safe and productive environment for workers and machines alike. The area occupied by this lab is now a green field site.
