ABSTRACT:
The present invention relates to an installation for replacing a member in a contaminated fluid circuit. It also relates to a process for replacing this member.
Installations for treating contaminated fluids, particularly radioactive fluids, comprise pipe systems in which the contaminated fluid flows. These systems or circuits have transfer, distribution, purification and cleaning members and the like, such as pumps, valves, filters, etc. These members are subject to wear, particularly when they have moving parts, and/or dirt or pollutants. It is therefore necessary to replace them by new members or overhaul them at intervals of varying length. Besides such replacements due to wear or pollution, it may be necessary to replace one member by another having different characteristics, e.g. one pump by another pump having different operating principles and/or flow rates.
