Protective device for atomic power stations and method of reducing pressure in structure encompassing the atomic power plant

摘要

The safeguard of the invention is intended to nuclear power plant (4) and surrounds each nuclear power station with a formation dome (1). Dome (1) inner wall (2) includes heat proof material and is attached to frame structure, therefore the closeable hole inner wall of structure (2) offers and shut-off valve (8), especially for the spring of the power of those outward openings. It guides in rocky execution saddle hole (37) that inner wall (2) is formed by steel plate and is equipped between each room (6,7) in external cover (32) and inner wall (2). Chamber (6,7) be provided with filter device (9) with replaceable insertion piece be used for filter out most fine grained size for radionuclide that lead to annular space extend and inner wall (32) between external cover (2). Toric space formation blending space, which is connected to, leaks through external cover (32) and outer space.
