NUVIA UK – ModuCon

The problems associated with temporary containment such as integrity and secondary waste arisings are largely overcome with the ModuCon system. The modular concept offers a versatile robust containment with very few technical or safety limitations.

Originally developed at the Winfrith Technology Centre, ModuCon has been employed for over 20 years in maintenance and nuclear decommissioning operations involving plutonium and other radioactive/toxic materials. During this time, ModuCon has established an enviable track record.

Erection of the designed containment can be carried out by the NUVIA ModuCon installation team or by customer staff; a combined team is often the best approach. First the floor is prepared, and the requirements for this vary. Existing substrates may be utilised or covered with a heavy duty strippable coating. However, a suitable decontaminable sheet material is often laid to provide a firm platform and working base.

The false floor is overlaid with tough PVC and protective coatings. When wet operations are to be carried out, an integrated steel bunded base can be provided.

On completion of the work a final tie down coating is applied to the inside of the containment. This sandwiches contamination between layers. This is then removed by physically stripping the coating for safe disposal and producing minimal secondary waste. The panels are left clean and can be handled and transported without any special precautions. ModuCon® panels have been re-used many times in different configurations and on different sites or facilities.

Our experience of users’ problems has shown that the system often provides the only solution that offers an acceptable combination of safety and economy.

The ModuCon® system is tailored to suit the requirements of each user, and the enclosure can be as large or small, simple or complex as the job demands. The standard panels (900 mm wide) are easily handled and assembled. Non-standard panels are readily available and the enclosure may incorporate any of the
following options:

• Entry/exit area with (optional) shower or wet swabbing area
• Ports for material “posting” and services
• Windows for viewing and lighting
• Mobile ventilation and filtration plant
• Lifting equipment
