Objectifs<\/h2>\n

D\u00e9veloppement d’un ROV destin\u00e9 \u00e0 r\u00e9cup\u00e9rer des s\u00e9diments radioactifs (surmont\u00e9s par une hauteur d’eau de 1.50 m) stock\u00e9s dans des silos de l’usine AREVA de La Hague. Le v\u00e9hicule est \u00e9quip\u00e9 d’une pompe haute puissance et d’un syst\u00e8me de d\u00e9compactage des boues, ainsi que d’un syst\u00e8me de ballasts permettant un contr\u00f4le pr\u00e9cis de l’altitude du ROV dans la tranche d’eau, ainsi que de la force d’appui sur les s\u00e9diments en phase de r\u00e9cup\u00e9ration.<\/p>\n

Il se caract\u00e9rise de plus par :<\/p>\n

    \n
  • L’emploi de mat\u00e9riaux adapt\u00e9s aux contraintes radiologiques et physico-chimiques extr\u00eames<\/li>\n
  • Le d\u00e9port de toute l’\u00e9lectronique sensible au niveau du poste de contr\u00f4le surface, et notamment les variateurs des propulseurs<\/li>\n
  • Une compacit\u00e9 compatible avec les contraintes de confinement et d’insertion du ROV dans les silos<\/li>\n
  • Une fiabilit\u00e9 tr\u00e8s \u00e9lev\u00e9e et une optimisation du design par rapport aux contraintes de maintenabilit\u00e9 et de d\u00e9contamination<\/li>\n<\/ul>\n

    Le concept d\u00e9velopp\u00e9 peut facilement \u00eatre adapt\u00e9 \u00e0 d’autres probl\u00e9matiques, comme par exemple :<\/p>\n

      \n
    • D\u00e9pollution de sites sous-marins (zones portuaires, aquaculture, …)<\/li>\n
    • D\u00e9senvasage de retenues d’eau hydro-\u00e9lectriques ou agricoles<\/li>\n
    • R\u00e9cup\u00e9ration de r\u00e9sidus industriels (usines chimiques, mines, \u2026)<\/li>\n<\/ul>\n
        <\/ul>\n

        Particularit\u00e9s du d\u00e9veloppement<\/strong><\/h2>\n

        Outre les sp\u00e9cificit\u00e9s dues \u00e0 l’environnement nucl\u00e9aire, le d\u00e9veloppement a donn\u00e9 lieu \u00e0 un travail important de fiabilisation des propulseurs, qui ont subi un programme de qualification particuli\u00e8rement s\u00e9v\u00e8re : 1500 h de fonctionnement continu \u00e0 pleine charge dans une eau satur\u00e9e en argile, avec des inversions brutales de r\u00e9gime.<\/p>\n

        Ceci a permis le d\u00e9veloppement de solutions d’\u00e9tanch\u00e9it\u00e9 dynamiques particuli\u00e8res dont b\u00e9n\u00e9ficient l’ensemble des propulseurs sous-marins d\u00e9velopp\u00e9s par\u00a0Subsea Tech pour ses diff\u00e9rentes gammes de ROVs.<\/p>\n
