<p>PROBLEM TO BE SOLVED: To provide a reactor containment vessel which prevents an air lock from being deformed due to the action of large external force such as an earthquake while suppressing a large increase in cost.SOLUTION: A reactor containment vessel includes: a main body 2 storing a reactor pressure vessel; and an air lock 3 provided to an outer wall 5 of the main body 2 in a manner to penetrate through the outer wall 5. The air lock 3 is supported by each of support members 8, 9 inside and outside the outer wall 5 of the main body 2. A buffer structure part 7 for relieving transmission of vibration between the outer wall 5 and the air lock 3 is provided at the periphery of a portion in which the air lock 3 penetrates through the outer wall 5 of the main body 2.</p> |
