PROBLEM TO BE SOLVED: To provide a reactor where the vibration of a throat of a jet pump is suppressed. SOLUTION: In a first means, the provision of a bellow in a straight pipe section of the throat converts the section from a rigid body structure into a flexible one and allows the bellow to absorb vibration. In a second means, vibration is absorbed by converting a portion or the whole of a stationary plate connecting a nozzle to a bellmouth in the upper part of a throat into a flexible structure. In a third means, the vibration at the lower end of the throat is suppressed by connecting the lower end of the throat to the upper part of a diffuser with a vibration suppression plate which takes on a flexible structure.
