The invention relates to a device (24) for removing foreign bodies (22) from the bottom (8) of a nuclear reactor pressure vessel (2) that is flooded with water (4) and comprises coupling connectors (10) projecting into the interior (20), which can be placed on one of the coupling connectors (10) and contains a suction device (30) which comprises a suction tube (32) having an intake opening (36) that can be moved relative to the remaining device (24), a filter (38), an outlet (42) and a suction pump (40) delivering water (4) from the intake opening (36) via the suction tube (32) and the filter (38) to the outlet (42). In a corresponding method, the device (24) is placed on one of the coupling connectors (10) and a suction device (30) is operated, wherein the suction pump (40) delivers water (4) from the intake opening (36) through the suction tube (32) via the filter (38) to the outlet (42), the intake opening (36) for taking in the foreign bodies (22) from the bottom (8) and/or the coupling connectors (10) is moved relative to the remaining device (24), and the foreign bodies (22) are collected in the filter (38). |
