    摘要： An instrumented capsule for nuclear fuel irradiation tests in research reactors. The capsule includes an outer shell; a rod tip assembly assembled to a lower end plate of the shell, thus absorbing impact; fuel rod assemblies supported in the shell by means of support tubes and housing therein sintered fuel bodies and in-capsule instruments, such as thermocouples and self-powered neutron detectors (SPND); a protective tube connected to the upper end plate and protecting instrument control cables; and a guide pipe connected to the inclined extension part of a junction tree and guiding the instrument control cables to a control unit provided outside the reactor. The capsule further includes upper and lower end caps provided around the upper and lower ends of the shell; and a lower stopper and an upper stopper fitted over the protective tube to be supported in the upper portion of the irradiation hole of the reactor and to be locked to the locking clamp provided at the upper portion of the chimney of the reactor, respectively. The capsule is used to measure in real time the properties of nuclear fuels irradiated in the reactor during a nuclear fuel irradiation test, thus providing nuclear fuel irradiation test data required for the design of nuclear fuels and the determination of in-pile performance and structural integrity of the nuclear fuels.

    摘要： An instrumented capsule for material irradiation tests in research reactors. The instrumented capsule performs an optimum material irradiation test under a testing environment similar to the operational environment of a real reactor. The capsule minimizes the influence of flow-induced vibration caused by forced-circulation-type coolant flow in a research reactor, and overcomes the problems experienced in the conventional breakable parts of instrumented capsules which may be broken during the process of loading/unloading the capsules in vertical irradiation holes of reactor pools. The instrumented capsule includes a capsule main body installed in the vertical irradiation hole. The capsule main body consists of a shell and several instruments, such as thermocouples, dosimeters, a vacuum control pipe, and heaters housed in the shell. The capsule main body also includes heat media, specimens set in the heat media, insulators interposed between adjacent heat media, upper and lower end plugs to seal the ends of the shell, an upper guide spring unit to vertically place the capsule main body in the irradiation hole, and a reinforced lower fixing unit assembled with the lower end plug. The instrumented capsule also includes a connecting means for connecting the capsule main body to a capsule control system installed outside the reactor pool.
