METHOD TO AUTOMATICALLY DECONTAMINATE NUCLEAR FUEL ROD AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC G21F9/00 

FIELD: power engineering.

SUBSTANCE: device of automatic cylinder cleaning by its wiping with a tape comprises facilities of automatic positioning of a cylindrical element, on which the specified section is located along its axis; the first master roller made as capable of tape winding and the second slave roller made as capable of tape reeling, besides, the rollers are made as capable to rotate around axes that are parallel to the axis of the cylinder section; the first facilities of the tape positioning arranged on the way of the tape passing between the first two rollers and around the section of the cylinder, besides, the positioning facilities are made with the possibility to transport the tape in radial direction relative to the axis of the cylinder section so that it could contact with the cylinder section along the first specified arc and could occupy a more remote position without contact with this section. There is also a method of automatic peripheral decontamination of the cylinder section.

EFFECT: group of inventions makes it possible to reduce contamination of rods after their enclosure into a shell to a lower level that it is required according to technical conditions.
