    摘要: Provided are a probe and an apparatus for measuring a thickness of an oxide layer of a fuel rod, capable of testing claddings of inner and outer fuel rods of a nuclear fuel assembly without disassembling the nuclear fuel assembly. The probe includes a fuel rod transfer region on which an eddy current sensor capable of continuously testing claddings of outer fuel rods of a fixed nuclear fuel assembly is mounted. Further, the apparatus includes a frame in which a cylinder driven in upward and downward directions is mounted, a first probe connected to one side of the cylinder in order to test claddings of outer fuel rods of a nuclear fuel assembly, and a second probe connected to the other side of the cylinder in order to test claddings of inner fuel rods of the nuclear fuel assembly.

    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.
