Problems solved by technology

In addition, if the glove box has a large size, it is necessary to cut the sealing envelope into different parts to manufacture and transport it under pollution-free conditions, and finally dispose of it once the inside of the envelope is irreversibly contaminated

Embodiment Construction

[0034] figure 1 A protective and disposable envelope-like intervention tent 1 according to the invention and covering a glove box 2 (shown in dashed lines) to be disassembled is shown. For the sake of clarity, the invention will be described by way of example with a protective tent for dismantling a glove box. It will however be clear that the invention is not limited to this embodiment and that the tent can be used for interventions with all types of polluted objects. This protective tent 1 comprises a sealing envelope 3 forming a sealed environment, which is necessary since it minimizes the risk of contamination during interventions inside the glove box. The airtightness of the protective tent is ensured by the use of an airtight closure which provides a seal between the different sheets 20 and 21 forming the envelope-like tent.

[0035] The envelope is supported by straps 5 applied on metal supports 6 forming the outer metal frame. Stands provide a structural and versati...

Abstract

A protective and disposable intervention envelope shaped tent (3), in particular for intervention on contaminated objects, said tent being leak tight and comprising at least a first (20) flexible flat sheet and a second (21) flexible flat sheet, said tent further comprises at least one first mechanically resistant and re-usable closure member (22) having a first and a second part (23), said first part being attached to said first sheet and said second part (24) being attached to said second sheet, said first closure member being provided to attach and detach said first (20) and second (21) flexible sheet to each other, said tent further comprising at least one second leak tight and re-usable closure member (25,26) comprising a first flap (25) connected in a leak tight manner to said first sheet (20) and a second flap (26) connected in a leak tight manner to said second sheet (21), said first and second flap being provided to be leak-tightly attached to each other by a leak tight seal and being applied in such a manner that said first and second closure members extend substantially parallel to each other and so as to overlap said first mechanical closure member when said first and second flaps and sheets are attached to each other.

Description

technical field [0001] The present invention relates to a protective and disposable envelope-like intervention tent, in particular for the intervention of contaminated objects, said tent being airtight and comprising at least one first and second flexible flat sheet. In particular, the invention relates to a protective tent for interventions on objects such as nuclear contamination or contamination by bacteria or viruses. The invention also relates to leak testing of nuclear enclosures and storage of protective tents beyond their useful life. Background technique [0002] When dismantling nuclear installations, such as mixed oxide fuel ('MOX') or other plutonium-containing fuel rod production lines, a major problem is dismantling the enclosure, which has been internally contaminated with radioactive material, in a manner that cannot allow leakage of radioactive contamination. Several methods have been proposed for dismantling nuclear-contaminated enclosures. This form of e...
