Title (EN) A DEVICE FOR REMOVING A RADIOACTIVE DEPOSITION
(FR) DISPOSITIF DESTINE A ENLEVER UN DEPOT RADIOACTIF
Abstract:
(EN) A device for removing a radioactive deposition from a fuel assembly (1) in a nuclear plant comprises a container (2), arranged to accommodate the fuel assembly, first means (3, 4, 5), arranged to feed a fluid into and through the container (2), said fluid being provided to release the deposition from the fuel assembly (1) by means of abrasion and transport radioactive deposition material out of the container (2) and second means (6, 7) being arranged to receive the radioactive material transported out of the container (2) by the fluid. In the device, at least second means (6, 7) are arranged in a $g(g)-radiation-dampening medium.
(FR) L'invention concerne un dispositif permettant d'enlever un dépôt radioactif d'un assemblage combustible (1) dans une centrale nucléaire. Ce dispositif comprend un conteneur (2) conçu pour loger l'assemblage combustible; des premiers moyens (3, 4, 5) conçus pour amener au conteneur (2) et faire passer par le conteneur (2) un fluide destiné à enlever le dépôt radioactif de l'assemblage combustible (1) par abrasion et évacuation hors du conteneur (2); et des seconds moyens (6, 7) conçus pour recevoir la matière radioactive évacuée du conteneur (2) par le fluide. Dans le dispositif, au moins les seconds moyens (6, 7) sont placés dans un milieu d'amortissement des rayons $g(g).
