    摘要: Provided is an apparatus for measuring outer diameters of fuel rods of a nuclear fuel assembly, in which the fuel rods are standing upright and are used in a light water reactor. The apparatus includes a support unit fixed to a floor at a lower portion thereof so as to be kept insulated from vibrations caused by external forces, a measuring unit mounted on the support unit and moving up and down to measure the outer diameters of the fuel rods, and a transducer cooperating with the measuring unit, converting the measured outer diameters of the fuel rods into electrical signals, and sending the converted signals to the outside. Thus, the apparatus moves up and down to measure the outer diameters of the fuel rods, so that it can accurately check abnormalities in the outer diameters of the fuel rods.

    摘要: Provided is a nuclear fuel assembly positioning system having a built-in solenoid valve box in an apparatus for testing nuclear fuel used in an atomic power plant. A work table is installed at a predetermined position within an underwater fuel storage pool, and a solenoid valve box connected to two pneumatic hoses extending from the outside is integrally installed on an test table so as to drive the test table, so that only the two pneumatic hoses simplified as a gas supply hose and a gas discharge hose are connected with the test table, and thus the nuclear fuel assembly is accurately and rapidly positioned as to be able to conveniently perform testing without the structures around the hoses being interfered with when pneumatic motors are operated.
