چکیده مقاله
By placing the nuclear fuel assembly inside the reactor and start a nuclear fissionreaction, the nuclear fuel rod changes such as temperature changes, internal pressurechanges, structural changes or dimensional changes, which must be monitored to ensureits safe operation One of the important and investigated cases in this article is thedimensional changes of the fuel stack and the fuel rod clad The non destructive testduring irradiation or the test after irradiation can be done to measure these changes Thetest during irradiation can obtain more useful information about dimensional changes inthe real time ofthe reactor operation and is therefore of interest For this purpose, the fuelrod must be instrumented with the desired tool such as LVDT, ultrasonic transducer,fiber optic, or others This article studies the different tools for dimensional measurementand how to equip the fuel rod According to the study, among different equipment, theLVDTs are the most common type and are widely used in this field
