PROBLEM TO BE SOLVED: To provide a nuclear reactor that can prevent propagation of vibration to a structure in a vessel.SOLUTION: A nuclear reactor includes: a reactor core internal structure 20 that has a sound source part 100 which generates sound; a vessel 11 that houses the reactor core internal structure 20 therein, and has a measurement position for measuring the sound propagated from the inside to the outside; and reflection parts 15 and 16 that are provided in at least a part of the vessel 11 so as not to block a measurement path from the sound source part 100 to the measurement position, and reflect the sound generated from the sound source part 100.SELECTED DRAWING: Figure 2 |
