    • Provided is a reactor vessel having multiple alignment keys for measurement and evaluation of vibration of the internal structure thereof, wherein the multiple alignment keys connect and support an upper guiding structure and a core supporting barrel and are formed radially. Under the alignment keys are formed multiple through holes through which measurement cables for measuring vibration of the reactor vessel internal structure, which is generated as a reactor coolant flows. According to the present invention, the through holes are formed in the alignment keys formed in the reactor vessel, and a measurement cable connecting path is configured. And, measurement cables connecting the core supporting barrel and the lower supporting structure pass through the through holes along the cable connecting path and combine with the measurement cables positioned in the upper guiding structure in order to measure and evaluate vibration generated in the core supporting barrel and lower supporting structure due to the flow of the reactor vessel coolant. Therefore, the overall vibration measurement and evaluation of the reactor vessel internal structure formed in the reactor vessel can be more easily performed.
