Document Type and Number:

WIPO Patent Application WO/2011/030497

Kind Code:

A1

Abstract:

A nuclear reactor containment vessel (8) comprises a nuclear reactor's primary containment vessel (3) which contains a nuclear reactor pressure vessel (2), a nuclear reactor's secondary containment vessel (4) which is disposed outside the nuclear reactor's primary containment vessel (3) and which has the pressure resistant properties and the air-tightness which are equivalent to those of the nuclear reactor's primary containment vessel (3), an airbag (5) which is disposed within the nuclear reactor's secondary containment vessel (4) and which, when a failure occurs in the nuclear reactor's primary containment vessel (3), expands while receiving and encapsulating a high-pressure gas discharged from the inside of the nuclear reactor's primary containment vessel (3), and a gas phase vent pipe (6) which connects the nuclear reactor's primary containment vessel (3) and the airbag (5).
