VENTILATION DEVICE, NUCLEAR REACTOR BUILDING WITH SAME, AND VENTILATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ventilation device for ventilating hydrogen-containing gas from a nuclear reactor building without delay even in a building zone which is surrounded by a structure and in which hydrogen is prone to be accumulated, the nuclear reactor building with the ventilation device, and a ventilation method.SOLUTION: A ventilation device comprises: heating section 11; a block member 12; and a transfer mechanism. The heating section 11 generates heat by treating gas including hydrogen gas and releases the treated gas. The block member 12 is provided at a position downstream of the heating section 11, and is configured to be able to interrupt and block a gas flow due to the gas released from the heating section 11. Furthermore, the transfer mechanism moves the block member 12 so that the gas flow transitions from a blocked state to a passing state as a result of the heat generation by the heating section 11. A nuclear reactor building comprises: at least one zone surrounded by a building frame structure; and the ventilation device provided in this zone.SELECTED DRAWING: Figure 1
