description PROBLEM TO BE SOLVED: To efficiently remove hydrogen generated in a reactor containment vessel and a vent device, and to prevent high temperature and overpressure of the vent device.SOLUTION: A vent device 20 for a reactor containment vessel, provided at a reactor containment vessel vent line 58 for connecting a reactor containment vessel 52 to a stack 59 for exhaust, includes: a vent filter container 1; a vent filter inlet 10 provided at one end part of the vent filter container 1; and a vent filter outlet 13 provided at the other end part. Inside the vent filter container 1, there are arranged, in order from a side of the vent filter inlet 10, an oxidation part 2, a radionuclide capturing part 3, and a hydrogen rebinding part 4.
