| 20100296617 | INSPECTION, MAINTENANCE, REPAIR, AND OPERATING METHODS FOR NUCLEAR REACTORS - A method of inspecting, performing maintenance on, or repairing a nuclear reactor may include operatively connecting a fixing device, a first track, an arm including one or more second tracks, and an effector to form an apparatus; inserting the apparatus into the reactor; fixing the apparatus within the reactor; and operating the apparatus. At least one of the one or more second tracks may include at least three track sections. The arm may have a contracted length. The arm may have an expanded length. The expanded length may be greater than two times the contracted length. The first track may include one or more motors configured to move the arm relative to the first track. A method of operating a reactor may include shutting down; inspecting, performing maintenance on, or repairing the reactor; and starting up the reactor. | 11-25-2010 |
| 20110075784 | NUCLEAR FUEL CELL REPAIR TOOL - A method of repairing a nuclear fuel cell wall and tools useful for performing that repair are described. A repair tool may be used to align a jack near a region of a bent or distorted structural component of nuclear fuel cell and that jack may be used to apply a force to that structural component. Application of such a force may serve to bend the structural component of a nuclear fuel cell in a way to restore the structural component to its position before damage occurred. The repair tool includes a way of mounting that tool to a fuel cell, positioning elements to align the tool near a structural deformation or bent element and a jack that may be use to apply a force to at least one structural component in a fuel cell. | 03-31-2011 |
| 20110182393 | METHOD OF EVALUATING QUANTITIES RELATING TO THE DISTORTION OF A NUCLEAR FUEL ASSEMBLY - A method of evaluating at least one quantity relating to the distortion of a nuclear fuel assembly, the method including the following steps: the nuclear fuel assembly is placed in a volume of water bounded by an upper free surface; a camera is placed outside the volume of water, above the free surface; at least one image of at least one lateral face of the nuclear fuel assembly is taken; the at least one image is analyzed graphically and the at least one quantity relating to the distortion of the nuclear fuel assembly is deduced therefrom. | 07-28-2011 |
| 20120128112 | INSPECTION APPARATUS - The present invention relates to an inspection apparatus for detecting defects in a test object in a liquid filled space. The inspection apparatus comprises an inspection body, a camera and vertical positioning equipment adapted to adjust the position of the camera in a vertical direction. The vertical positioning equipment comprises an elongated element having a vertical portion, a fastening member adapted to attach the detection device to the vertical portion, a vertical drive mechanism adapted to provide a motion of the vertical portion of the elongated element such that it moves the detection device to a desired vertical position along a vertical axis. The vertical portion of the elongated element has the property of being torsion rigid about the vertical axis. | 05-24-2012 |
| 20120183114 | METHOD AND APPARATUS FOR TESTING AN ANNULAR WELD ON A MAIN COOLANT LINE CONNECTED TO A REACTOR PRESSURE VESSEL OF A NUCLEAR POWER PLANT - A method and an apparatus for test an annular weld at a main coolant line connected to a reactor pressure vessel in a nuclear power plant, include a self-propelled submersible vehicle which is introduced into an opened, flooded reactor pressure vessel. The submersible vehicle has at least one test device to be placed against an inner circumferential surface of the main coolant line and moved in circumferential direction of the main coolant line. The submersible vehicle is advanced into the main coolant line, which is also flooded, and is fixed in the region of the weld by radially deployable spreading or extension arms. The test device is then placed against the weld and is moved therealong in the circumferential direction. | 07-19-2012 |
| 20130142297 | STEAM GENERATOR UPPER BUNDLE INSPECTION TOOLS - In inspection system for inspecting the interior of a steam generator includes, in one aspect, a first boom and a second, telescoping boom having a proximal end pivotally attached to the first boom and a distal end bearing a delivery capsule, the delivery capsule defining a storage bay. The inspection system includes a first robotic inspection vehicle dimensioned to fit in the delivery capsule storage bay and itself defines a storage bay. The first robotic inspection vehicle includes at least one inspection camera and at least one lighting system. The first robotic inspection vehicle further includes cabling connecting the first robotic inspection vehicle to the delivery capsule. The inspection system also includes a second robotic inspection vehicle dimensioned to fit in the first robotic inspection vehicle storage bay. The second robotic inspection vehicle includes at least one inspection camera and at least one lighting system and further includes cabling connecting the second robotic inspection vehicle to the first robotic inspection vehicle. | 06-06-2013 |
| 20140211901 | NUCLEAR POWER PLANT CABLE AND MONITORING SYSTEM THEREFOR - The present invention relates to a nuclear power plant cable including: conductors; at least one or more insulation layers adapted to correspondingly surround the conductors; a sheath adapted to surround the insulation layers; and monitoring means adapted to monitor the states of the insulation layers or the state of the sheath in real time. | 07-31-2014 |
