Lainsa has developed the Atomic Snail, an equipment for underwater decontamination of nuclear reactor vessel flanges, which represents an important advance for the nuclear sector because it allows process automization and, consequently, a dose reduction in and greater safety.

This pneumatic propulsion system is operated remotely and moves at a constant speed with the hability to move both forwards and backwards.

While moving, it sweeps the surface of the flange and it vaccums the working area of the brushes, in order to then filter the vaccumed fluid and retain the loosened particles.

By carrying out the cleaning remotely from the refuelling platform, an important reduction in the operational doses associated with this activity is achieved.
