Embodiment Construction

[0027] Identical or identically acting components have the same reference symbols in all figures.

[0028] Figure 1-3 The shown protective cover (shroud for short) 2 serves as a passive protection device for ventilation openings 4 in the installation space 6 of a nuclear engineering installation, in particular a nuclear power plant. It comprises a frame 10 made up of 4 steel profiles 8 each having a U-shaped cross-section. Such as image 3 As shown, the side walls 12 of the profiled part 8 all point outwards. The profile parts 8 that abut one another are welded to one another at corners 14 cut into wedges. The frame 10 has a rectangular shape with longitudinal sides 16 and transverse sides 18 . The terms "longitudinal side" and "transverse side" are used herein only to clearly denote directions, and in no way are they intended to imply length ratios. That is, lateral sides 18 can be different from figure 1 In some cases, it can also be longer than the longitudinal side ...

Abstract

The invention relates to a protective covering (2) used for ventilation opening(6) in a construction space (6) of the nuclear engineering construction. The covering (2)has advantages of simple structure, and simple installation as well as production, on one side, the covering (2) is provided with the air flowing cross section, which is big enough, on the other side, the covering (2) can be used to prevent the destructive emission objects from entering the building. Therefore The covering (2) has multiple elongate profiled elements (32) arranged in an attachment plane in a rectangular frame (10) with a longitudinal direction (20) and with a transverse direction (22). The profiled elements are aligned parallel to each other in the longitudinal direction. Each profiled element includes an L-shape or V-shape cross-section with two legs, which collide in a tip. The tip points in the transverse direction. A distance between the successive profiled elements is selected such that a rectilinear passage is not formed between the successive profiled elements.

Description

technical field [0001] The present invention relates to a protective cover (shroud for short) used for a facility space of a nuclear facility or a ventilation opening of a facility building. Background technique [0002] For example, the so-called diesel engine room belongs to the facility space of nuclear engineering facilities located outside the reactor safety cover, and there are safety-related refrigerators and / or corresponding diesel generators in the diesel engine room. The walls of such installation spaces are equipped with air intake / exhaust openings (vents for short), which are generally formed in the form of large prism-shaped reinforced concrete channels. The shape and passage of such passages generally require high design costs and expenses. On the one hand, the ventilation openings must ensure an air flow cross-section sufficient for the perfect operation of the cooling unit. On the other hand, there should be sufficiently high intrusion protection against so...
